Psoriasiform lesions on trunk and palms.

BUMC PROCEEDINGS 2003;16:236–238 A34-year-old man presented with a 2-week history of a relatively asymptomatic truncal rash with gradual spread to involve his face, limbs, palms, and soles. Approximately 10 days before onset of the rash, he experienced a flulike episode with mild arthralgias, sore throat, and mild headache that had reappeared intermittently prior to his evaluation. Physical examination revealed a healthy looking man with a diffuse papular eruption and minor associated scaling involving the trunk and limbs (Figures 1 and 2) with discrete erythematous lesions on the palms and soles (Figure 3). The patient had mild scalp scaling, mild photophobia, and a moderate degree of adenopathy, especially in the groin and posterior neck.
