A man in his 60s presented with a 1-year history of a pruritic, dark red plaque on his right upper eyelid. No remarkable medical history was noted. Physical examination findings revealed a 4 × 2-cm erythematous, violaceous, indurated, scaly plaque with some papules on his right upper eyelid (Figure, A). Results of routine blood tests and biochemistry analysis were within normal limits. A biopsy sample was obtained for histopathologic examination (Figure, B).
