Summary : An otherwise healthy 23 year-old woman was referred to our department for the onset, four months before, of a non itching, slowly enlarging papule localised on the dorsal aspect of the right forearm; her familial and personal history were negative for cutaneous diseases. Physical examination showed a round, scaly, lilac plaque, measuring 3 cm in diameter (Fig. 1); the patient had no other skin or mucosal involvement. The lesion was surgically removed, and histopathological examination revealed orthokeratotic hyperkeratosis, hypergranulosis and focal vacuolar degeneration of the basal layer. In the papillary dermis a band-like lymphocytic infiltrate hugging the epidermis, together with melanophages, were present (Fig. 2). What is your diagnosis?
