[Solitary gastric plasmacytoma. Case report and review of the literature].

The authors report a case of extramedullary gastric plasmacytoma followed from the clinical onset of the disease until the death of the patient. The literature on this topic was reviewed. The male patient underwent total gastrectomy with left splenopancreatectomy when he was 40 years old; after surgery followed by adjuvant chemotherapy and radiotherapy, the plasmacytoma relapsed; the patient died 4 years after the first operation. Gastric plasmocytoma is a rare pathological entity; different postsurgical therapeutical approaches are derived from the inclusion of this gastric neoplasm in the lymphomas or in the extramedullary plasmacytomas. The authors emphasize a better response of the disease to adjuvant chemotherapy than to radiotherapy after surgery. it suggests the necessity of a separation of gastric plasmacytomas from the other gastric lymphomas.
