Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant inherited disease characterized by onset at a relatively early age, an excess of synchronous and metachronous tumors, and a variety of extracolorectal malignancies. Small bowel carcinoma reported, is included in the tumor spectrum of HNPCC, but the frequency of occurrence of this tumor in HNPCC patients is comparatively rare. In Korea, several cases of multiple primary cancers in patients with HNPCC have been reported, however, primary jejunal adenocarcinoma in conjunction with multiple primary cancers in the digestive tract has rarely been reported. Recently, we evaluated a 61-year-old male diagnosed with metachronous triple primary cancers of the jejunum, stomach, and colon. We report this rare case of primary jejunal adenocarcinoma as a part of metachronous triple cancers along with a review of the relevant literature. (Intest Res 2011;9:158-161)
