A man in his 50s presented with a history of pruritic lesions of the lower legs over the past 15 years that were unresponsive to topical corticosteroid therapy. On examination, he had multiple lichenified and ulcerated papules and nodules, some of them grouped in plaques located on the medial aspect of both shins (Figure, A). Occasional tense blisters were also seen (Figure, B). The patient’s family history was significant for similar cutaneous lesions in his father, brother, and cousin. Mild toenail dystrophy was also observed. A punch biopsy from the shin for histopathologic examination was performed (Figure, C and D).
