This paper reports one case with glucagonoma syndrome that resection of the primary glucagonoma in the pancreas was done. There was metastasis one in liver and lymph node. The definitive diagnosis was established by immunohistochemical analysis. The patient by immunohistochemical analysis. The patient remained well for 27 months and gained 5 kg of weight. Another experiences of diagnosis and treatment of 8 cases of malignant glucagonoma collected in chinese literature were reviewed. The clinical specialty of glucagonoma syndrome. diagnosis and management were discussed suggesting two points: on diagnosis the clinical specialty is a important clues: palliative primary tumor resection may be significant clinical improvement and prolonged survival.

From 1977 to 1987, six cases of heterotopic pancreas at the ampulla of Vater and the papilla were encountered. All patients were suffering from obstructive jaundice and misdiagnosed as having periampullary cancer and pancreaticoduodenectomy was done.

This paper presents an analysis of 35 GI epithelioid leiomyomas (leiomyoblastoma) including the authors' own 6 cases from 1975 to the end of 1987. Tumors were found in the stomach in 21 cases (60%), in the duodenum in 4 (11.2%), in the jejunum in 7 (19.8%), and in the ileum in 3 (8.5%). The male to female ratio was 1:1.2 ranging in ages from 11 to 68 with an average of 42. Of these, 82.8% were benign and 17.2% were malignant. No case was correctly diagnosed before the operation. Tumors were resected in 97.2% of the patients. In the author's opinion there should be two basic types of the tumor: benign and malignant, though the identification is often quite difficult. The mitosis, the size of primary tumor, the metastasis and recurrence of the tumor should all come into the consideration. Surgical resection of the tumor is the only effective treatment and all tumors should be treated as malignant.
