An eight-year old boy noted frequent episodes of loss of consciousness and clonic convulsion. The fasting blood sugar level remained always low ranging from 8 to 50mg/dl. A selective celiac angiogram demonstrated an opacified tumor stain measuring 2×2 cm with its feeding artery at the head of the pancreas. The tumor was removed, under diagnosis of insulin-secreting pancreatic tumor. After the operation, no more hypoglycemic attacks heve been observed. Histopathological and ultrastructural studies of the tumor revealed a malignant insulinoma. The diagnosis of malignancy was made in view of the presence of tumor cells within the small vessels, and their capsular invasion. The patient has not been placed on anticancer agents, but has been doing well 3 years after operation without evidence of recurrence.
