Unusual Facial Dermatosis

Abstract:  16 yo girl with 3 month history of annular dermatosis mid-forehead.

HPI:  This healthy 16 yo has had a 4 cm roughley circular plaque on the mid-forehead.  Takes no medications by mouth and is not aware of any OTC meds taken infrequently,  She has bued 1% hydrocortisone cream and also a topical imidazole without improvement.

O/E:  The lesion has fairly sharp borders.  The surface is somewhat gready.  KOH prep failed to demonstrate hyphae or spores.  The remainder of the cutaneous examination is unremarkable.

Clinical Photo:

Diagnosis:  The picture is suggestive of seborrheic dermatitis, but the circular nature is unusual. What are your thoughts?

Plan:  Betamethasone valerate 0.1% cream b.i.d. x 2 weeks sand then Elidel cream.  If it does not respond or if it recurs a biopsy will be done.

Arcuate and Circinate Facial Eruption

Presented by   Dr. Arnulfo Macadangdang

Cebu City, Philippines

Abstract:  18 year-old student with one week history of facial eruption

HPI:  The patient is an 18 yo man with a one-week history of an eruption on face and neck.  It is mostly asymptomatic.  He is an athlete, takes no medications and has no risky behaviors.  He had an upper respiratory infection around a month before onset. 

O/E:  There are arcuate and circinate lesions on cheeks, neck, and forehead.  Two similar lesions on u upper back. The scale is greasy.  No lymphadenopathy.

Clinical Photos:

Lab:  KOH negative

Diagnosis:  This has some features of seborrheic dermatitis, but it is not typical.  Sebosporiasis was another thought.  Evolving psoriasis?  Relationship to "URI" in October?

Questions:  Does this clinical picture suggest any specific diagnosis?

Follow-up:
5 Day F/U photos

 
The patient was seen 5 days after starting desonide 0.05% cream.  His skin lesions have esolved completely with mild post-inflammatory hypopigmentation.  The three lesions on back (not treated) have persisted. No new lesions.  Our tentative diagnosis is atypical seborrheic dermatitis.  Atypical Pityriasis rosea is also considered.  We do not feel serology for syphilis and HIV are indicated at this point, based on a discussion of risky behaviors.   Will taper desonide over the next two weeks and see patient back in a month as necessary.
