A case of extramedullary plasmacytoma of the skin in a 66-year-old woman is presented. The histologic findings showed aggregates of well-differentiated and occasionally binucleated plasma cells in the skin (cheek and buttock), liver, spleen and bone marrow. Electron microscopy confirmed the histopathologic diagnosis of plasmacytoma of the skin. The general features (sex, age, site of presentation and spread) of this extramedullary plasmacytoma and of this rare primitive entity with clinically primary cutaneous involvement are discussed. The differential diagnoses of extramedullary plasmacytoma of the skin from reactive plasmacytosis, solitary myeloma of the bone, multiple myeloma, plasma-cell leukemia and plasmacytoid malignant lymphoma are taken into consideration.
