Primary adenocarcinoma of the stomach associated with peripheral neurofibromatosis: report of a case.

A 55-year old man with von Recklinghausen's disease was admitted to our hospital for investigation of weight loss, anorexia, and abdominal discomfort. Endoscopy findings revealed impairment in the extendability of the stomach by air, and barium meal studies showed a well-contracted stomach. On exploratory laparotomy, the whole of the stomach was found to be grossly shrunken with thickening of the walls suggesting a "linitis plastica" stomach. Histological findings confirmed stage III poorly differentiated diffuse infiltrative adenocarcinoma of the stomach. This report describes a rare case of "linitis plastica" stomach in a patient with peripheral neurofibromatosis (NF-1) indicating that the NF-1 disorder does not spare an individual from other common neoplastic disorders.
