Gastrointestinal Adenomatous Polyposis Associated with Small Cell Neuroendocrine Carcinoma of the Rectosigmoid: A case report.: Wan Seop Kim, Eun Kyung Hong, Kang Sik Kim, Kwang Soo Lee, Jung Dal Lee; Korean J Pathol. 1996;30(11):1040-1044.

Abstract PDF: In adenomatous polyposis coli there are many colonic and extracolonic manifestations, and various combinations of these induce different clinical presentations and syndromes. We experienced a unique case of adenomatous polyposis of the large intestine and stomach in a 39-year-old man. In the colon, small cell neuroendocrine carcinoma rather than adenocarcinoma had developed, which did not contain adenomatous or carcinomatous foci. The adenomatous polyps in the colon were all small and sessile with no cancerous or precancerous change two years after the resection of the symptomatic gastric adenomas, even though the gastric adenomas were larger and showed dysplastic change. We think this case is another variant of adenomatous polyposis syndrome.

Gastroduodenal Adenomas and Carcinoma in Patients with Familial Polyposis Coli.: Seung Sook Lee, Woo Ho Kim, Yong Il Kim; Korean J Pathol. 1993;27(3):263-267.

Abstract PDF: Gastric lesion in familial polyposis coli is commonly presented with fundic gland hyperplastic polyps, but duodenal and gastric adenomas together with their carcinomatous transformation have been rarely described in familial polyposis coli mostly by case reports. We present three cases of gastric adenomas in familial polyposis coli with one in synchronous development of gastric adenocarcinoma in Korea. All three cases had the family history related to familial polyosis coli and received proctocolectomy because of synchronous development of colonic adenocarcinoma. One patient developed gastric polyposis and adenocarcinoma 8 years after colectomy, and the remaining two presented with multiple polyps either in the stomach or duodenum synchronously at the time of the diagnosis of familial polyposis coli with colonic adenocarcinoma. None disclosed any evidence of Gardner's syndrome. We conclude that association of gastric adenomas in familial oplyposis coli is not uncommon and gastric adenoma-carcinoma sequence is an another important participating mechanism to understand the histogenesis of gastric carcinoma in Korea.

Development of Desmoid and Mesenteric Fibromas following Total Colectomy for Adenomatous Polyposis Coli in Gardner's syndrome.: Jung Hee Cho, Yong Il Kim; Korean J Pathol. 1989;23(4):465-469.

Abstract PDF: We describe a case of polyposis coli, which was followed by development of desmoid in the rectus adbominis muscle and fibromas in the mesentery during an interval of two years. This case supports the hypothesis that, in Garder's syndrome, the traumatic injury by colectomy triggers an unusual fibrous proliferation in the peritoneal cavity and incision site under the possible genetic basis.
