Plasmacytosis, first described in 1976, is a rare disease that primarily affects patients of Japanese descent. The disease includes both cutaneous and systemic types, and histology displays a florid dermal infiltrate of polyclonal plasma cells. In addition to the classic and characteristic clinical presentation of red-brown, flat nodules or plaques on the trunk, patients may also have anemia, fever, and hypergammaglobulinemia. The lymph nodes are the most frequently affected extracutaneous site; however, involvement of liver, lung, and kidney has been reported. The pathogenesis is still elusive. These authors performed a retrospective study of six patients (4 men; mean age, 49 years) to further characterize the features of plasmacytosis.
