Cutaneous plasmacytosis limited to the extremities in a white patient: an unusual clinical picture.
Cutaneous plasmacytosis is an uncommon disease characterized by a cutaneous polyclonal plasma cell infiltrate usually associated with polyclonal hypergammaglobulinemia. It has predominantly been found in Japanese patients and it is rare in white patients. Clinically, this condition manifests as multiple red to dark brown skin lesions that mainly are located on the trunk. We report the case of a 66-year-old white woman who presented with reddish brown to violaceous macules and plaques restricted to the extremities. The histopathologic findings, laboratory data, and systemic studies led us to the diagnosis of cutaneous plasmacytosis.
