Abstract

The case involved a 71-year-old man. When he was 60-year-old, he got an early gastric cancer of IIc type at the antrum. On preoperative examination for gastrectomy a retroperitoneal tumor was pointed out. The 9×7×4cm ovarian shaped tumor was located in the retropanreatic space between IVC and portal vein. Subtotal gastrectomy and extripation of the retroperitoneal tumor was carried out. The retroperitoneal tumor was dignosed as extraadrenal pheochromocytoma during the operation, because he was attacked by hpertension on extirpation of the tumor. When he was 67-year-old, he got another early gastric cancer of IIa type in the residual stomach and underwent total resection of the residual stomach. Three years later when he was 70-year-old, two small liver tumors and two small retroperitoneal tumors with diameters of 1_??_2cm were detected in the follow up study, There were no symptoms of excessive catecholamine secretion, but these small tumors were diagnosed as recurrent foci of pheochromocytoma by 131I-MIBG scintigraphy and slightly increased catecholamine values in blood and urine. In spite of previous two surgical operations, another exploration was done and these recurrent foci were resected successfully. Ten months later now, we don't find any recurrent foci on follow up studies as yet.
