A 36-year-old man presented with a 5-year-history of a recurrent, self-healing, asymptomatic, cutaneous eruption that initially had developed on his arms and later had involved his legs and trunk. He had not had any previous treatment. Physical examination revealed numerous erythematous papules scattered over the trunk and extremities, with sparing of the head and neck region (Figure 1 and Figure 2). Some of the papules had a lichenoid clinical appearance. There was no lymphadenopathy or hepatosplenomegaly. A complete blood cell count and the results of liver function tests and a chemistry profile were within normal limits.
