[A case of triple carcinomas: stomach carcinoma surgically removed, renal tumor, and carcinoma of the remnant stomach].

Reported is the case of a 57-year-old male patient, who manifested tarry stool and who had undergone a subtotal gastrectomy at our hospital in 1983 for an early carcinoma, type IIc, which proved to be a well differentiated tubular adenocarcinoma. Three years later, he returned complaining of epigastralgia, although no evidence of a recurrence could be seen. An abdominal ultrasonogram and a CT scan, however, revealed a right renal tumor and he subsequently underwent an operation for the removal of a renal cell carcinoma, a clear cell type. In 1988, he again was readmitted to hospital, this time because he easily became fatigued. An upper GI series and gastroscopy located a polypoid lesion in the remnant stomach. Thus, a total gastric resection was performed, and the lesion was diagnosed as being a well differentiated tubular carcinoma, an early gastric cancer, type I. Triple carcinomas are very rare, and the details of this case are discussed.
