Dr. Michael Sherling (Dermatology): A 44-year-old woman was admitted to this hospital because of generalized, painful, ulcerated cutaneous lesions.
The patient had been well, except for eczema, until 4 years before admission, when erosions on the scalp developed, followed by a generalized papular skin eruption. Betamethasone dipropionate and cephalexin were prescribed, without improvement. Examination by a dermatologist 2.3 years before admission revealed scarring alopecia and multiple hyperkeratotic erythematous plaques on the trunk and arms. Pathological examination of biopsy specimens of two lesions on the left arm were reported to show hypertrophic lichenoid dermatitis with eosinophilia. The results of laboratory tests
