SCC of Scalp in a 94 yo woman

Presented by Dr. Antoine LeBlanc
Houlton, Maine 

The patient is a 94 year old woman in good health.  She has no significant underlying health conditions.  For the past couple of years she has had a painless, slowly enlarging erosive squamous cell carcinoma of the scalp. It is 2.2 cm in diameter. The calvarium is exposed.  Histopath shows focal perineural invasion.

What is the Goldilocks approach here? 

Although her general health is good, she does not drive and trips to hospital are difficult to arrange.  She is reluctant to pursue interventions, but the morbidity of her tumor is worrisome.

Follow-up 2.10.26
After three months of palliative treatment with a Calcium Alginate Wound Dressing and nothing else, clinically there is no residual cancer and the would looks better.  It has shrunk in diameter, in addition.  For the present, the patient has no pain or any specific complaints regarding this lesion.

 

 

 

Psoriasis in a 9 yo Girl

The patient is a 9 year old girl who presents to the office for evaluation of psoriasis of 4 months duration. Initially, this started on the bilateral knees with erythematous scaly plaques that have generalized since onset. She was prescribed topical mometasone by her pediatrician with little improvement. 

Physical exam: On exam, patient has erythematous, scaly plaques varying in size on the chest, back, upper extremities, abdomen and lower extremities. She has also started to develop a few smaller plaques on the face. 

This has been difficult on the patient who has been made to sit out of her swim classes due to the instructors fear of her spreading the rash to other students. Her parents are going through a contentious divorce and her mother feels her skin is causing the patient significant distress. Otherwise, the child is healthy and denies any recent illnesses. There is no family history of psoriasis.

We are presenting her case to seek advice from those who have treated widespread psoriasis in pediatric patients. She is currently using clobetasol ointment, however we wonder if systemic treatment is necessary at this time. 

 

Clinical Images

Note: While this is relatively mild at this time, the short history suggests that it may become more or a problem, and it is impacting on the patient's life at this time. We are reluctant to prescribe MTX for a 9 year old and NB UVB is not an option as she lives far from a unit.

Linear Forehead Dermatitis

 The patient is an otherwise healthy 30 yo man in good general health.  For two months he has had a slightly pruritic dermatitis on his forehead.

Clinically, we considered En Coup de Sabre (Linear scleroderma)

Punch biopsy showed:
Lichenoid interface and perifollicular dermatitis with postinflammatory pigment alteration.  No features of localized scleroderma.  These findings are suggestive of discoid L.E. or linear L.P.

Treatment was initiated with clobetasol ointment.  Will switch to tacrolimus ointment if response is good.
