How would you diagnose this woman's eczema?
A 46-year-old female with a history of eczema presents with a 2-month history over the summer of itching on her arms, mostly in a sun distributed pattern. She has some rash on her legs but it is mild and asymptomatic. She denies taking any new medications or exposures. She feels she actually flared a little on a methylprednisolone dose pack.
How would you diagnose her eczema?
A. Cutaneous lupus erythematosus
B. Atopic dermatitis
D. Leukocytoclastic vasculitis
E. Poymorphous light eruption
(Answer and discussion on next page)
Answer: Atopic dermatitis
This patient had a biopsy that confirmed the diagnosis of an eczema flare. It was concluded that the sun had produced an exacerbation without any evidence of a photodermatitis. She was given a new topical regimen and placed on dexamethasone in case she was developing a sensitivity to methylprednisolone and did much better.
