Extramedullary cutaneous plasmacytoma.
Neoplastic degeneration of plasma cells can show different clinical features, including multiple myeloma and plasma cell leukemia. Skin involvement is not rare in patients with multiple myeloma, and represents a poor prognosis. Appearance of a cutaneous plasmacytoma without the involvement of bone marrow is very rare. We describe a patient who had cutaneous plasmacytoma, with two solitary lesions of the oral cavity. The patient also showed a cerebral involvement, but no evidence of multiple myeloma, with normal-appearing bone marrow.
