Know When to Cut, Know when to Punt

The patient is an 87 yo man with a mild dementia. He lives in an assisted care facility. Has an attentive and caring daughter. In October of 2007 he had a wide-local excision of s large SCC on the left forehead by a general surgeon. Path report showed "clear margins." When seen on May 30, 2008 a 4 x 3 cm recurrence was noted. The picture of the right TMJ area shows a scar from micrographic surgery from a similar lesion the patient had ~ 10 years ago. His daughter said it took 6 months to heal.





Questions:
1. What contributes to the aggressive behavior of this small subset of SCCs?
2. Would you refer to Mohs, XRT, or just watch?
3. Are you comfortable playing God with patients like these?

Comment: There is a subset of SCCs that metastasize and kill patients. MA Weinstock and his collaborators have written on this subject.

Weinstock MA, et. al.
Nonmelanoma skin cancer mortality. A population-based study.
Arch Dermatol. 1991 Aug;127(8):1194-7.

Department of Medicine, Veterans Affairs Medical Center
Providence, RI 02908.

To estimate the magnitude of nonmelanoma skin cancer mortality
and describe itsparameters, we reviewed the medical records of
all deaths certified as due to this cause among Rhode Island
residents from 1979 through 1987. After excluding acquired
immunodeficiency syndrome-associated Kaposi's sarcoma, we
confirmed that nonmelanoma skin cancer was the cause of death
for 51 individuals, a quarter of the number of melanoma deaths
reported. The age-adjusted nonmelanoma skin cancer mortality rate
was 0.44/10(5) per year. Fifty-nine percent were due to squamous
cell carcinoma, and 20% were due to basal cell carcinoma. Most
appeared actinically induced. Among deaths from SCCs, the mean age
was 73 years. At least 80% of the squamous cell carcinomas metas-
tasized, and 47% arose on the ear. None appeared due to refusal of
treatment. Among deaths frombasal cell carcinoma, the mean age was
85 years, and refusal of surgical intervention was documented in
40%. Study of nonmelanoma skin cancer mortality provides for estimation
of the magnitude of this problem, complements otherstudies of
prognosis, and helps guide prevention, early detection, and treatment.

Two Foot and One Hand Disease

These are the hands of a 35 year-old plumber I saw recently. He was not aware of a dermatitis of his feet, but inspection showed mild moccasin-type T. pedis on both feet and subtle onychomycosis. KOH prep from the right hand was positive for septate hyaline hyphae. We all see two foot and one hand disease regularly. Do you have any theories as to why only one hand is involved? This is a peculiar dermatologic vignette.

Penile Pain

The patient is 40 yo heterosexual male in a monogamous relationship for the last 6 years. Neither he nor his partner has a history of having had sex with anyone else ever before.

Three months ago he had the onset of pain at the tip of his glans during coitus and experienced pain also on pulling at the tip of his foreskin. A month later he noticed a few grouped "vesicles" at the ventral tip of his glans. These lesions have persisted unchanged. The pain in these lesions persists since being first noticed.
Clinical Photo:


The wife is asymptomatic although she had symptoms suggestive of vaginitis 3-4 months back which improved on clotrimazole pessaries (this was almost the same time when the patient developed pain during coitus which has never subsided).

What is the diagnosis?
What would you do at this point?

Note: Two respondents have suggested "Pearly Penile Papules." This does not look like a typical case of PPP. For comparison a picture is below. PPP is usually around the corona and is rarely this symptomatic.

21 yo man with warty plaque on foot

Presented by Henry Foong, Ipoh, Malaysia

A 21 yr old student presented with 5-year history of warty growth on the
right foot. It started as a small lesion which gradually got bigger.

Pertinent findings on examination were raised hyperkeratotic plaque 5 x 3 cm
on the medial border of the dorsum of the right foot. It has a verrucous
surface with blackish dots. Regional nodes were not palpable.




Clinically he has chromoblastomycosis of the right foot.

A biopsy was done and the epithelium shows marked acanthosis with elongation
of rete ridges and intraepithelial collections of neutrophils. The dermis is
densely infiltrated by lymphocytes, plasma cells and few neutrophils.
Culture of organism was not done.

I may repeat the biopsy and perform fungal culture.

I plan to treat him with liquid nitrogen together with some combination
therapy with antifungals: itraconazole 100mg bd ( 200mg bd??) for several
months together with another antifungals. 5FU or IV amphotericin.

Would appreciate your comments on this patient.

No Man is an Island

Thallium poisoning with skin manifestations

Presented by Professor Khalifa Sharquie
Baghdad, Iraq

History: A few weeks ago, an outbreak of thallium poisoning occurred in Baghdad and all of the patients had positive tests for thallium. We had the opportunity to see cases with skin manifestations. All patients gave a history of eating cakes and presented to hospital with nausea, vomiting followed by mental and peripheral neurological complaints. The case I am presenting was that of a 30 yo adult male referred to me two weeks after poisoning. He had severe hair loss, both diffuse and patchy, affecting mainly scalp and body hair. Also he had a non-pruritic rash affecting the face, limbs and groins.

O/E: The striking findings were severe anagen hair loss, diffuse and in patches. The hairs were easily plucked and microscopically were typical anagen phase. The next important finding was dermatitis-like picture that covered the face especially around the mouth and the limbs mainly on the dorsae of both hands. The groins had intertrigo simulating tinea cruris. The rash was dusky red and ecchymotic in appearance.

Photographs:





This picture was strange enough to make one think about the following Differential Diagnosis:
Acquired zinc deficiency
Pellagra
Erythema multiforme
But only suspicion can lead you into right diagnosis. Accordingly, before the definite diagnosis was established, we gave oral zinc sulfate 100mg 3 times a day for some patients. Surprisingly they recovered and resolved.

Reason Presented: Thallium is nice rat poison since it is colorless, tasteless and odourless. It can be used as massive lethal chemical weapon and is practiced this way in Iraq as a way to kill people. It is my opinion that thallium should be prohibited and considered as a chemical weapon like nitrogen mustard. It is better to let rats run free than to kill human beings.

Reference:
A good article on this subject appeared in the Archives of Dermatology in January, 2007. Short-term thallium intoxication: dermatological findings correlated with thallium concentration.

Our Western civilization began in the Fertile Crescent. Iraq was at the epicenter. The strory told here diminishes all of us. Professor Sharquie bravely bears witness as he helps and serves his people.

Stumped...

Abstract: 60 yo man with unusual cutaneous ulcers and erosions
Presented by Dr. Hamish Dunwoodie, Moncton, New Brunswick
HPI: The patient is a disabled physician's assistant who injured his scalp on a low basement ceiling beam around a year ago. When he was first seen he had a thick escar over the area. This was debrided and cultured. It grew Staph aureus with the usual sensitivities and he was treated with wet compresses, dicloxacillin and bactroban ointment. Since his initial visit 4 months back it has not gotten smaller and now the central portion reaches the calvarium. Over the past six weeks, he has developed similar lesions on shoulders and upper back. By history these began at sites of ECG leads.

Pertinent medical history is positive for insulin-dependent diabetes, hypertension and coronary artery disease. His medications include insulin, warfarin, enalapril, furosemide, ASA, oxycodone.

O/E: 3 cm ulcer mid parietal area of scalp. Erosions on both shoulders, surface somewhat escharotic. Some with irregular borders.

Photos:


4 months later








Lab: Occasional skin cultures positive for S. aureus (not MRSA), CBC shows mild normochromic normocytic anemia. (Hct 32.6.Hgb 11.2).

Pathology: "Ulceration with scar. No evidence of malignancy." Repeat biopsy April 18, 2008 from new lesion on shoulder send to Canadian National Pathology Lab.

Diagnosis: Non-healing erosions etiology unclear. One always considers factitial disease in health care professionals with atypical skin lesions and this man also has free access to needles as a diabetic. In a year, the scalp lesion has shown no tendency to improve.

Further Treatment: He was treated with topical corticosteroids in case this was erosive pustular dermatitis of the scalp (no response) and imiquimod in case erosion might have been hypergranulation tissue. (no response) We ordered Duoderm dressings, but they were too expensive for the patient.

Questions: Where would you go from here? Diagnostic and therapeutic suggestions.

A Leg to Stand On

Abstract: 85 yo man with cellulitis and lymphedema s/p bypass surgery

HPI: In 2000, this retired professor had CABG surgery with saphenous vein harvesting of the left leg, In 2002, while visiting Vienna, he was hospitalized for cellulitis of the left leg and treated with i.v. antibiotics. In the subsequent years, he has had progressive lymphedema of the left leg with the development of elephiantiasis nostra verrucosa. In the past 6 months he has had four documented episodes of cellulitis which have necessitated antibiotics. Recently, he has developed a generalized dermatitis. His medications include: atenolol, amiodarone, digoxin, diovan, thyrpid, Coumadin, Lovastatin, ASA. He has a possible allergy to penicillin (has not taken it in 40 years). He is otherwise quite healthy and intellectually alert.

O/E: Chronic lymphedema left leg with erythema, scale and some honey-colored crust. The leg in involved from just below the knee to the foot. The left leg is only minimally warmer than the right leg. In addition, he has a wide-spread dermatitis consisting of erythematous scaly patches on legs, arms and abdomen -- sparing the face.

Photos:






Lab: His internist did a skin culture and CBC b efore sending him here (results not back) . He was on Bactrim at the time of the culture.

Diagnosis: Recurrent Cellulitis s/p saphenous veif harvesting wit the development of chronic lymphedema and early elephiantiasis nostras. This was reported in 1982 (see Reference). The wide-spread dermatitis may be an "id" reaction.

Questions:
1) What has been learned about this entity since 1982?
2) Should he be rechallenged with penicillin and kept on long-term antibiotic prophylaxis.
3) What role does "hypersensitivity" to bacterial exotoxins play in the dermatitis.
4) Does anyone have magic for cases such as this?
5) Allergic contact dermatitis will be ruled out by patch testing.

Comment: My plan at the moment is to "clean up" any residual infection, consider prophylactic antibiotics and work on the dermatitis. I will refer him to a lymphedema center, if possible, for evaluation. Aggressive management of his leg swelling will help. He was told not to bathe the leg and I think this sets him up for infection. Your thoughts will be greatly appreciated. This man's life revolves around his leg. He is a keen student, a political scientist and in his later years he must focus exclusively on a leg. Let's give him "a leg to stand on!"

Follow-up: The patient was treated with compression stockings, cephalexin 250 mg qid for two weeks (based on sensitivities), desoximetasone 0.25% cream and lymphatic massage. There was no evidence of tinea pedis. He has improved markedly.

Reference:
Recurrent cellulitis after saphenous venectomy for coronary bypass surgery.
Baddour LM, Bisno AL.
Ann Intern Med. 1982 Oct;97(4):493-6.

We describe a previously unreported complication of coronary artery bypass
grafting, recurrent cellulitis. Five patients had 20 episodes of acute
cellulitis, each occurring in the lower extremity in which saphenous venectomy
had been done. The cases were striking because the patients presented with high
fever and considerable systemic toxicity. The appearance of the lesions, presence
in one case of obvious associated lymphangitis, and prompt response in three
instances to therapy with penicillin alone all suggest group A streptococcal
infection. In one case, a beta-hemolytic, bacitracin-susceptible Streptococcus
strain was isolated from the lesion. The pathogenesis of this syndrome remains
obscure but, based on our understanding of postsurgical erysipelas, this
cellulitis likely results from the interplay of several factors, including local
compromise of lymphatic drainage, direct bacterial invasion, and acquired
hypersensitivity to streptococcal exotoxins.

Recurrent Cheilitis in a 37 yo Woman

Abstract: 37 yo woman with 18 year recurrent cheilitis

HPI: This 37 yo woman has had recurrent cheilitis for 18 – 20 years. She works as a medical assistant. At one time, she was thought to be latex sensitive because blowing up balloons makes her feel sick, but a RAST test was negative. The episodes last five to six days. The day before the present episode she had eaten a “Mediterranean Dip” which included cucumber, garlic, feta, tomato, and horseradish. She noted nothing till the next morning when there was mild erythema of upper lip. She may have a history of mild atopic dermatitis. She can recall no meds she took before this or other episodes.

O/E: Erythema and mild crusting of lips and adjacent glabrous skin. Remainder of exam normal. Occasionally she’ll have mild erythema around outer canthi.

Photos:




Lab/Path: N/A

Diagnosis: ? Allergic Cheilitis. Role of Foods? Doubt Fixed Drug Eruption. To me this looks like an allergic contact cheilitis.

Questions: What would be the best way to work this up? This woman has 3 - 4 episodes per year, so it is unlikely that her cheilitis is related to something whe uses daily, and she does not recall anything she applies only intermittently.

Allergic contact cheilitis in the United Kingdom: a retrospective study.

Am J Contact Dermat. 2003 Jun;14(2):75-7.
Abstract: Environmental and Contact Dermatitis Unit, Amersham Hospital, Whielden Street,
Amersham, Buckinghamshire, HP7 0JD, United Kingdom. strauss@strauss.karoo.co.uk

BACKGROUND: To date, only a few cohorts of patients with allergic cheilitis have
been described, most of them from Australia and Asia. OBJECTIVE: To establish the
prevalence of cheilitis in a UK specialist contact dermatitis clinic and to
identify the most common allergens. METHOD: We analyzed our patch-test database
in a tertiary referral center in the United Kingdom, retrospectively. All
patients presenting with cheilitis over a 19-year period (1982 to 2001) were
included. RESULTS: Data were available from a total of 146 patients. A positive
allergic patch-test reaction was thought to be relevant in 15% of the patients (n
= 22) and to be of possible relevance in 6.8% (n = 10). Of the 22 patients with
relevant allergic results, 95% (n = 21) were women. The most common allergens
included fragrance mix (mainly cinnamaldehyde, oak moss, and isoeugenol) in 41%
of patients, shellac in 18%, colophony in 18%, and Myroxylon pereirae in 14%. For
half of the patients, the allergen was believed to stem from lipsticks or lip
products. Eighteen percent of patients with allergic cheilitis reacted to only
their own products. CONCLUSIONS: Patients should be tested to extended
lipstick/cosmetic vehicle series in addition to standard series. As a significant
percentage of patients react to their own products only, a thorough clinical
history and testing to patients' own products are important.

Double Helix

We often see problems for which there may be no simple solution. Ear lobe keloids are encountered with regularity; but keloids of the helix and triangular fossae are unusual. Some of you may have a simple trick for patients like these:

Patient # 1.
Abstract: 25 yo woman with ear keloid.

HPI: This 25 yo Asian woman pierced the triangular fossa of her right ear 2 years ago and developed a keloid which is pruritic and whose appearance bothers her.

O/E:


Patient # 2
As I was getting case # 1 ready to publish on this site, a second patient presented for evaluation and treatment.
This is a 16 yo girl with a one year history of a keloid of the left triangular fossa. She had a professional piercing done two years ago. This lesion is painful.




This patient had an "Industrial Piercing" with a 14 guage stainless steel rod.

Comment: Earlobe keloids are commonly seen and reported. But I could find no helpful articles about helix and triangular fossa keloids. I suspect that these lesions are not rare, since I have seen two in a few weeks in a small New England town. Perhaps, these are harbingers of an epidemic! One of these young women pierced her own ear, and the other was a professional job.

Questions:
These can not be simply excised and then injected with TAC like the more common ear lobe keloid. Wound closure would be problematic.
How would you approach these women?
Any role for shave excision followed by imiquimod?
Do you think TAC alone will work? 20 mg per cc, 40 mg per cc?
Does anyone have experience with similar lesions?

Weird Erythema

Presented by Omid Zargari
Rasht, Iran

This patient referred to me with a weird erythema on his frontal area for the past two years.
He is a 45 y.o. kidney transplant patient whose medications include cellcept, cyclosporine, erythropoetin alpha and simvastatin. He believes that this began after he started simvastatin.



Your thoughts will be appreciated.

Acrolentiginous Melanoma from Malaysia

Here is a case from Jahor Baru, Malaysia. In North America, Europe and Australia the patient would have had more extensive studies; but one must keep in mind that there are disorders in Malaysia that are better handled there than here. Melanoma is far less common in SE Asia and their resources are allocated differently.

Abstract:
70 yo woman with ALM right sole

Presented by S.E. Choon, Consultant Dermatololgist

HPI: This 70 year-old Chinese lady presented in April 2006 with a 1-year history of a growth on right sole which was biopsied and diagnosed as melanoma. We do not have level and thickness. She refused below knee amputation and hence was referred to us in July 2006. She had radiotherapy in Sep/Oct 2006 in private centre.

P.M.H: Diabetes mellitus of 10 years, well-controlled with metformin 500 mg bd and glibenclamide 5mg daily.

O/E: see figure Fig. This shows her lesion in 2006 before XRT. There were no other positive findings. The current lesion very similar. Patient coming back next week.

















Work UP:
CXR and CT neck, thorax and abdomen were clear in 2006 - in February 2008 CT scan last week showed several small right obturator lymph nodes. I was not too happy without a repeat CT and get one done last week. Size of LN not mentioned.

Pathology:
2006: Superficial spreading type (apparently down to subcutis for initial biopsy. Pathologist in Singapore wrote: "nodular type with vertical growth and ?superficial spreading"
2008: Recent lesion biopsy report was short and sweet-recurrent melanoma

Diagnosis: Acrolentigious Melanoma

Questions:
1. How would you classify this patient?
2. What would you recommend for this patient?
3. The patient initially refused amputation. Is there a lesser procedure that might help her now?

Your answers and comments are welcome.

Painful Edematous Plaques

Abstract: 24 yo woman with 2 month history of transient plaques torso and extremities.
HPI: This 24 yo woman was diagnosed with hyperthyroidism in October of 2007. She was treated with radioactive iodine and carbamazole in November and December. Her dermatological manifestations began after both treatments. She reports ~ 20 episodes of painful plaques on torso and extremities. These last 1 - 3 days and clear completely. They are hot, tender, and painful in certain locations. She was first seen in my office on February 26, 2008 with an acute episode which was 24 hours old.
O/E: Healthy-appearing young woman. A solitary plaque was noted on the upper back. The borders were well-defined. The area was hot and painful and slightly erythematous. The patient had trouble taking her shirt off for the exam.
Photos:
Note: The border is outlined for clarity with a blue marking pen in photos 2 and 3.

Lab:
She has had various blood tests done by other physicians and I've called for results. I ordered a CBC and ESR yesterday. Thyroid antibodies will be obtained unless her other physicians have ordered these.
Pathology: A deep incisional wedge biopsy into the panniculus was obtained.
Diagnosis: I have not seen anything like this. The short duration of the lesions suggests angioedema or urticarial vasculitis. But, I have never seen a similar case with such large lesions. One wonders about the relationship of her thyroid disease and possible autoantibodies.
Reason Presented and Questions: It is instructive to present an undiagnosed case for discussion. Others may have seen a similar patient. Every day, we see something unique to us. In some cases, our colleagues may be of invaluable assistance. Your comments are most welcome.

Facial Pigmentation in a 31 yr old woman with Protein S deficiency

A 31 yr old woman presented with one year history of pigmentation on her face. It appeared as sun burn and confined to the facial areas with sparing of the areas underneath the eyes and nose. It was made worse after application of some skin care products. She was otherwise well.

She had a past history of hypercoagulation and mitral valve prolapse with Protein S deficiency and is on warfarin.

Examination of the skin showed diffuse hyperpigmentation on the face extending to the frontal hairline, preauricular hairline and mentum. The areas under the eyes and nose were spared.

Blood counts and biochemistry were normal ANA serology mildly positive. Titre 1:80 (RR<80)

Differentials: photodermatitis > LE > melasma > irritant dermatitis

Q Is the serology titre of 1:80 significant? Could this be LE or melasma? Would you biopsy her skin? If you biopsy, where would you biopsy her? Thanks for your comments.

Asymptomatic annular lesions on face and hands

Submitted by Khalil Alhamdi M.D.
Associate Professor of Dermatology
Basrah, Iraq

Abstract: A 25-year old woman with 3-year history of asymptomatic annular lesions on face and hands

History: A 25-year-old woman presented with 3-year history of multiple asymptomatic annular lesions involving the face and the dorsa of both hands that gradually increase in size. She had received different modalities of treatment without improvement.

O/E: Young aged women presnted with multiple asymptomatic annular atrophied hyperpigmented patches with hyperkeratotic border that affect the face in a mask-shaped destribution and the dorsa of both hands.

Clinical Photo:





















Lab: All relevant investigations were normal.

HPE: revealed features suggestive of porokeratosis















Diagnosis: Porokeratosis of Mibelli

Comments: This woman was misdiagnosed as fungal infection and lichen planus for which she received treatment without benefit. On clinical and histopathological bases we put her on topical 5Fu in addition to irregular courses of isotretnion because of poor compliance and inavailability of the latter drug in our country.

Questions:
1. What is the experience of our colleagues in seeing such unusual presentation?
2. What is your treatment suggestion to help this poor lady.

Umbilical Erosions

[ See end for final diagnosis]
Abstract:
71 yo woman with three week history of genital, anal and umbilical erosions.
HPI: This healthy 71 yo woman had vaginal prutitus for a few weeks. She saw her gynecologist who prescribed an estrogen cream. It got worse. She was then given clobetasol oint. It did not improve. She tried acyclovir ointment -- not much change. I saw her at this point. I recommended continuing clobetasol ointment, but after a few days getting worse. No new meds. Takes occasional acetoaminophen and diphenylhydramine.
O/E: Periumbilical erosive dermatitis. No frank vesicles. There was only faint erythema of the vulva and anal areas and very slight erosion left groin.



Lab: CBC normal, Chemistries normal. KOH from umbilicus negative. Bacterial culture taken.
Pathology: Biopsies for H&E and perilesional for DIF done Feb. 8, 2008
Diagnosis: I am considering the following:
A vesiculobullous disorder
Fixed drug eruption (but have no likely candidates)
Contact dermatitis unlikely.
HSV a long shot.
Periumbilical cellulitis? B-Strep perianal cellulitis can look similar
What have I missed?
Questions: What are your thoughts? Biopsy and culture should be ready in three days.

The bacterial skin culture grew out Group A Beta Strep. The pathology was consistent with cellulitis. No evidence of an acantholytic process. It is likely that this began with a perianal/vaginal streptococcal cellulitis and spread to the umbilicus. Periumbilical streptococcal cellulitis has not been reported in adults. The patient was started on Pen VK 250 mg qid and mupirocin ointment. Fout days later she was almost completely clear. Unfortunately, the fluorescent correction was not on when picture was taken.

Question from Iraq












Dear Colleagues,

Pityriasis alba, a disease of young children, is a superficial dermatitis which often presents in two stages: first the erythematous stage which over time developes into (the second) a whitish stage. In Iraq, we see, not infrequently, children with pityriasis alba-like patches that change over time into true vitiligo and then progress and spread to vitiligo in other parts. Many of these patients have a positive family history of vitiligo. At the initial visit it is sometimes is very difficult to tell parents whether their children have vitiligo or not and we fall into big dilemma.

I see many of these and treat them as vitiligo. They respond as well as as those we treat for pityriasis alba.

Question: I would like to ask our colleagues whether you have any similar observation? I intend to initiate a study about this problem shortly.

Khalifa Sharquie

Note: The current case on the classic VGRD site is also from Iraq. Please view it, too.

Pathology:

Diagnosis or DDx: Reed Nevus (aka Pigmented spindle cell nevus)
Questions: For inerest
Reason(s) Presented: When I first saw this patient, I thought it was a blue nevus. I sent the history and digital images to a few friends. Drs. Ian McColl and Stelios Minas thought it was a Reed nevus and recommended excision. Biopsy was done and confirmed their opinion.
References: The Reed Nevus is considered a variant of the Spitz nevus. It presents as a well-circumscribed deeply pigmented nodule on the extremities of young adults. Under the microscope, it resembles the Spitz nevus but is composed of spindled melanocytes with heavy melanin pigmentation. As in a Spitz nevus, this nevus is symmetrical with maturation and lack of deep dermal mitotic figures. Excision of suspected Reed nevi is recommended. For more information see: The Doctor's Doctor
