Clinical, laboratory, and pathologic findings from a case of malignant extramedullary plasmacytoma of the skin are presented. To our knowledge, this is the 11th reported case of extramedullary plasmacytoma of the skin and the second reported case with a complete follow-up and postmortem examination. In these two cases, surgical excision of the tumor mass, radiation therapy, and chemotherapy were ineffective. At necropsy, visceral metastases were found, but there was no bone marrow involvement.
