위암과 신장암이 병발한 중복암

Primary multiple cancer means that more than two cancers occur independently in an individual. There have been many reports on primary multiple cancer since Billorth reported it for the first time in 1889. Owing to advancement of diagnostic procedures, reported cases of primary multiple cancers have been increased in number. The most frequent association in stomach cancer was followed by esophagus, larynx, liver, uterus. Here we report 1 case of primary multiple cancer who was a 60-year-old woman with epigastric pain. Endoscopy disclosed white patch and irregular base lesion on the antrum. A CT scan of the abdomen showed a lobulated soft tissue mass in the left kidney. The biopsy specimens showed adenocarcinoma on stomach and renal cell carcinoma on kidney. (Korean J Gastroenterol 1995;27:734 - 738)
