HYPOGLYCEMIA ASSOCIATED WITH INTRAABDOMINAL LEIOMYOMA AND LEIOMYOSARCOMA IN 6 DOGS

In 6 dogs that had hypoglycemia (resting blood glucose concentration < 50 mg/dl). Tumors were large (12 to 24 cm) and arose from intra-abdom inal structures including the jejunum, pylorus, duodenum, stomach, and liver. Four dogs had a leiomyoma, and 2 dogs had a leiomyosarcoma. In those dogs in which the tumor was successfully removed at surgery, bl ood glucose concentration returned to the reference range after tumor resection. Four dogs lived for at least 12 months after tumor resectio n, without redeveloping hypoglycemia.
