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.

Black Papule in a Child

Abstract: 11 yo boy with long history of black lesion left arm
History: The lesion has been present for years, little change but patient and parent are worried bout it.
O/E: 5 mm diameter papule with a peculiar serrated border

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

Eyelid Tumors

Submitted by Arash Abtahian from Shiraz, Iran

Abstract: 24 yo man with three year hx of eyelid lesions
History: This 24 man has come with 3 years hx of multiple translucent papule and nodules on the left upper lid. They are asymptomatic but he'd like them removed.
O/E: revealed multiple translucent papules and nodules some of which showed bluish hue.
Clinical Photo(s):




Lab: N/A
Histopathology: Apocrine Hidrocystoma
Diagnosis or DDx: Apocrine Hidrocystoma
Questions: What is the best treatment?
Reason(s) Presented: Therapeutic suggestions?
References: Apocrine Hidrocystoma eMedicine: " Apocrine hidrocystomas can be incised and drained; however, electrosurgical destruction of the cyst wall often is recommended to prevent recurrence. Punch, scissors, or elliptical excision also can remove tumors. Multiple apocrine hidrocystomas can be treated with carbon dioxide laser vaporization. Multiple apocrine hidrocystomas can also be effectively treated with trichloroacetic acid."

Papular Unticaria

Abstract: 20 yo student with pruritic papules for three weeks

History: While on a ski trip in New Mexico, this young woman developed a few pruritic papules around the neck. Over the next few days, these spread to torso and extremities. Some of the lesions were grouped in a "breakfast, lunch and dinner" distribution. She is in excellent health: a ski racer.

Exam: 1/3/08: There were 40 - 60 6 - 8 mm in diameter erythematous papules on torso, upper and lower extremities and to a lesser extent face. No lesions on doubly covered areas. After treatment with topical steroids this improved, but then flared around a week later.
1/10/08: Many new papules, neck, torso, extremities. No longer "breakfast, lunch and dinner" distribution.





Lab: CBC pending

Pathology: Consistent with arthropod bites or drug reaction. Will add photos later. Specimen shows parakeratosis, epidermal hyperplasia with focal eosinophilic exocytosis and a moderately dense superficial and mid perivascular interstitial lymphocytic infiltrate with scatterred eosinophils.

Diagnosis: Papular Urticaria (PU)

Questions: This woman is a competitive athlete. She does not want to take prednisone while racing. The lesions are very widespread and potent corticosteroid creams do not give much relief. Hydroxizine, too, will blunt her competitive edge. What would you recommend.

Reference: There was a good review of PU by Hernandez and Cohen in Pediatrics in 2006. "Insect bite-induced hypersensitivity and the SCRATCH principles: a new approach to papular urticaria." It is available in full-text: Hernandez/Cohen

Zebibah

The zebibah, Arabic for raisin, is a dark circle of callused skin, or in some cases a protruding bump, between the hairline and the eyebrows. It emerges on the spot where worshipers press their foreheads into the ground during their daily prayers.

Here is a fine article in the NY Times on the ZEBIBAH.

One of our editors, Ben Barankin, published a letter on prayer marks in the International Journal of Dermatology. Barankin Letter

Dr. Barankin's letter was a comment on:

Iatrogenic or Not?

Your opinion is sought.
The patient is a 42 y.o. woman with a long history of cystic acne. Typically she gets a few lesions a year. She has many ice pick scars from previous lesions. She was offered isotretinoin years ago but declined and indeed the lesions are less frequent now. She presents for intralesional triamcinalone when whe wishes to have the cysts treated. She was seen on December 5, 2007 with a tender cyst on the medial aspect of the left eyebrow. It looked like a typical acne cyst and was injected with Kenalog 3 mg per cc. Two days later she started to develop eyelid edema. She went to the Emergency Room and was given parenteral Rocephin and Cipro 500 mg bid. The swelling persists.



On examination, one can see where the initial cyst was. It's ~ 90% resolved. Below it there's a firm linear band that feels like a lymphangitic vessel.

I assume this must be related to the initial inflammatory lesion or the intralesional injection. I searched MEDLINE but could come up with no similar cases. If this is secondary to intralesional steroids, it is not reported. Could the original lesion have been a pyogenic infection that looked like her past cysts and could eyelid edema be secondary to lymphatic obstruction? The ER doc recommended another dose of Rocephin.
Addendum: The patient has never had fever, headache or other findings suggestive of a pyogenic infection.

Has anyone seen a similar case? Diagnostic and therapeutic suggestions are welcome.

Palmar Lichen Planus?

This case was presented by Dr Khalil Alhamdi, Basrah Medical College, Iraq.

S.G, 62 yo woman, presented with bilateral itchy palms 2 years duration with poor response to treatment. Physical examination is normal apart from bilateral diffuse hyperkeratotic violaceous palms. All laboratory investigations were normal

Histopathology: histopathological examination showed typical features of lichen plaus.

Diagnosis: palmer lichen planus.

What is the experience of our colleagues in seeing such a presentation of palmer lichen planus? comment please.

Epidermal nevus affecting foot

A 22 year old man presented with a history of linear hyperkeratotic lesion on the right foot since age 7 yrs. It hurts his foot when he wear his shoes.

Examination of the right foot showed a localised hyperkeratotic plaque extending linearly to the medial malleolus. It was not tender or inflamed. My impression is that of an epidemal nevus. Appreciate your thoughts on diagnosis and treatment options.

Winter's Toes

Abstract: 18 yo boy with pruritic, erythematous toes.

History: The patient was referred by his pediatrician with complaints of red, itchy lesions on his toes for two to three weeks. The pediatrician was concerned because some of the lesions looked vasculitic. The patient is in good general health. A non-smoker. He recollected as the interview progressed that he'd had similar but less severe problems in the past.

Physical Exam: Erythematous macules, some hemorrhagic in appearance on toes. One lesion slightly necrotic.

Photos:

Lab: CBC, ANA and other tests ordered at pediatric office
Pathology: none

Diagnosis: Chilblains (Lupus Pernio)
Reasons Presented and Questions: Similar patients are seen two or three times a year in my office. The typical case is a child or young adult with pruritic erythematous macules or papules on the toes or fingers. The lesions can look necrotic and sometimes ulcerate. The person is otherwise healthy. Pernio is most commonly seen in fall or winter, but I've seen it in spring, too. The lesions are worrisome in appearance to physician, parent, patient. The index case here was worried that "my toes will rot off." His mother was worried about "lupus." I reassured them that this is a common, self-limited problem. While nifedipine may help, it's not necessary. Wear warm socks. Give it time. There's a good review on emedicine.com. It says: "The direct cause of pernio is cold exposure. Chronic pernio may be secondary to various systemic diseases as follows:
Chronic myelomonocytic leukemia
Anorexia nervosa
Dysproteinemias
Macroglobulinemia
Cryoglobulinemia, cryofibrinogenemia, cold agglutinins
Antiphospholipid antibody syndrome
Raynaud disease"

But it's usually easy to differentiate which ones are worrisome and the vast majority will be simple chilblains. One may need to use some clinical judgment. Not rush to unnecessary testing. In my experience, and from what I've read, this occurs more when it is cold and damp in thin individuals. Not bone chilling cold, but the cold of early winter. When it is really cold, good socks and footwear may be more the norm and can protect a susceptible individual from chilblains.

11/29/07 -- Patient just seen:
These are the toes of a 70 yo man who has had chilblains for the past 30 winters. His toes are uncomfortable, itchy and occasionally painful. He's had no chronic illnesses and enjoys good health.


Here is an excellent full text reference: "Pernio in Children" from the journal, Pediatrics.

Notched Nose

This 55 year-old woman had micrographic surgery for a basal cell of the left ala three years ago. The graft did not take and she has been left with a notched ala. The defect, in the center of her face, is more disfiguring than it appears in this photo.


Question: What kind of repair could be done at this time to give her a better functional and cosmetic repair.

Uncommon Warts

SRLAMAT DATANG!
Welcome, New Members from the Penang Conference
Early morning, view before we convened for our scientific sessions. Penang is an amazing place to meet new friends, relax and sample a singular culture.

Please look at two interesting cases.

This is the tale of two young patients with warts who were seen back to back on November 17, 2007. Verruca vulgaris (the common wart) is sometimes quite "uncommon."

1. This is a seven year old boy who has had acute lymphocytic leukemia fr three years. He has had recalcitrant warts for the past nine months. At present he has failed liquid nitrogen, TCA and imiquimod. His present medications include methotrexate, 6 mercaptopurine, vincristine and dexamethasone. Each therapy for his warts has resulted in more florid reappearance. This child has suffered a lot over the past few years. Clearing his warts would be a small but pleasant victory for him. Your comments will be appreciated.








2. This is a 12 year old girl who initially had a small wart on her knee. Her physician treated with TCA and then liquid nitrogen over a few months. Each time the wart recurred larger. One can see concentric rings from previous treatments. I'd like to find a treatment that won't cause permanent scarring. In theory, the wart will disappear in a year or two, so the therapy should be benign. I prefen not the use liquid nitrogen or cautery here. Have you had success with warts like these?

Eczema herpeticum

A 2-year-old boy presented with a 3-day history of vesicular eruptions on the mouth followed by extensive pruritic skin eruptions on the upper and lower limbs. This was preceded by fever. He was otherwise well.

Examination of the skin showed extensive eczematous lesions on the lower and upper limbs. Excoriations, erosions and vesicles were also noted on the affected areas. Vesicular lesions and erosions were noted around the mouth. He was afebrile.

Clinically he has eczema herpeticum.

This is disseminated herpes infection at sites of epidermal disruptions. He was treated with oral acyclovir 50mg 5x daily and oral cloxacillin 125mg qid. Wet compresses with diluted KMNO4 and topical mometasone cream was used for the weepy eczematous eruptions. The lesions gradually subsided with the treatment.

Buttock eruptions

This is an 11-month-old girl with a one day history of skin eruptions on the shoulders and gluteal areas. She was otherwise well. no fever. Feeding well. She was referred to me by a pediatrician.

Exam: symmetrical patches of erythematous vesiculopapules on the gluteal areas. Similar lesions were noted on the shoulders and chest. No lesions were noted on the upper limbs. Hep B was not checked.

Is this viral? Gianotti Crosti Syndrome?

Thanks.
