摘要：Extramedullary plasmacytomas are plasma cell tumors that arise outside of the bone marrow. They account for approximately 3% of plasma cell neoplasms and are most frequently located in the head and neck region. Five months after undergoing cholecystectomy, a 69-year-old patient presented with the pain under the right costal margin and a 12 kg weight loss. Computed tomography of the abdomen demonstrated irregular, vascular mass in the gallbladder fossa that dents towards the duodenum and the pylorus and lowers caudally to the hepatic flexure. His laboratory tests indicated normocytic anemia and showed elevated sedimentation rate. During operative procedure, a tumorous mass in the gallbladder fossa was found, inseparable of the peritoneum of the hepatoduodenal ligament and the IVb liver segment. Histopathological examination and immunohistochemical staining determined the diagnosis of the plasmacytoma. Total resection of the tumor was achieved and after 24-month follow-up patient showed no signs of local recurrence or dissemination of the disease.
