GASTRIC LEIOMYOSARCOMA ASSOCIATED WITH HYPOGLYCEMIA IN A DOG

Hypoglycemia associated with a large, gastric leiomyosarcoma was diagn osed in an 11-year-old, yellow Labrador retriever. The dog had persist ent hypoglycemia and low serum insulin levels. Although radiological a nd ultrasonographical evaluations suggested an abdominal mass involvin g the liver, a large, nonresectable, gastric mass was found during exp loratory laparotomy, Metastasis was not identified on gross inspection of the liver or abdomen, and no metastatic lesions were seen on thora cic radiographs, The dog was euthanized. Histopathological examination of the mass revealed a poorly differentiated, gastric leiomyosarcoma that extended into the mesentery without regional lymph-node involveme nt.
