title: Gastric extramedullary plasmacytoma in a dog.
abstract: A 10-year-old mixed-breed dog was examined because of a 6-week history of daily vomiting and sporadic diarrhea. On gastroscopy, a crateriform mass was observed on the greater curvature of the stomach. Partial gastrectomy and lymphadenectomy of a large mesenteric lymph node was performed. Gastric plasmacytoma with lymph node metastasis was diagnosed by histologic and immunoperoxidase methods, and chemotherapy was initiated with doxorubicin hydrochloride and diphenhydramine hydrochloride. The dog remains clinically normal 30 months after initial diagnosis. Although gastric plasmacytomas are rare in dogs, long-term survival appears to be better with this disease than with other types of gastric neoplasia.
