Itchy, violaceous papules and nodules on the thighs
A 39-year-old African-American man had a one-month history of numerous itchy “bumps.” Multiple firm, violaceous, 4- to 7-mm papules and scattered nodules were visible on his posterior neck, forearms, back, and posterior thighs. The rash was intensely pruritic, especially at night. He was not using topical or systemic treatments at the time of presentation. He denied any history of asthma, allergies, or eczema but acknowledged having a cat in the house. He had no history of comparable lesions.
