REPORT OF A CASE
A 71-year-old man was hospitalized because of a transient ischemic attack. The dermatology department was consulted to evaluate an eruption on the left side of the trunk that was thought to be herpes zoster. The rash had appeared abruptly 6 months earlier and had failed to respond to topical steroid treatment. There was no history of previous skin disease or other illness. The patient's only medication was aspirin.Physical examination revealed grouped 2- to 4-mm red-brown, scaly papules in a linear array overlying the left flank (Figure 1). There were no abnormalities of the nails or oral mucosa. A punch biopsy was performed (Figure 2).What is your diagnosis?
