A 53-year-old male, who was otherwise healthy and had not been taking any medications, developed bullous and erosive lesions on the trunk. He had previously been treated with oral prednisolone (25 mg/day) and cyclosporine (200 mg/day) at another hospital under the clinical diagnosis of pemphigus; however, his skin lesions recurred and he was therefore referred to our hospital. Physical examination showed diffuse coalesced erythemas and scales on the face, trunk and extremities. A biopsy revealed subcorneal acantholytic cleavage, and acantholytic lesions were observed in the granular layer of the epidermis (Fig. 1a).
