Actinic granuloma.
A 45-year-old man presented with a 3-year history of asymptomatic, annular, erythematous plaques on the face and neck. Histopathologic examination showed sarcoidal granulomas with an associated mixed-cell infiltrate, loss of elastic fibers, and no increase in mucin. These findings were consistent with a diagnosis of actinic granuloma, which is an uncommon, idiopathic disease that is characterized by granuloma annulare-like plaques on sun-exposed areas.
