A Case of Cutaneous and Systemic Plasmacytosis with an Unusual Clinical Presentation / 대한피부과학회지

ABSTRACT

Cutaneous and systemic plasmacytosis is a rare disorder that's characterized by a cutaneous plasma cell infiltrate accompanied by polyclonal hypergammaglobulinemia. Clinically, it appears as multiple red-brown plaques that mainly occur on the trunk, and this is sometimes associated with variable extracutaneous involvement. All the cases of cutaneous and systemic plasmacytosis reported in Korea have shown the typical skin manifestations on the trunk of the patients. Herein, we report on a case of cutaneous and systemic plasmacytosis and the patient presented with multiple erythematous to brownish patches on the face, neck and both axillary areas.
