A 17-year old female presented with a chief complaint of melena and epigastric pain. She had a family history of colon cancer, her mother having been diagnosed with hereditary nonpolyposis colorectal carcinoma (HNPCC). After close examination including double-balloon enteroscopy, the patient was diagnosed with small bowel carcinoma, in spite of her young age. Here we report this rare case of small bowel carcinoma in a young patient with a family history of HNPCC.

  • Fig. 1. Abdominal CT finding. It revealed segmental eccentric wall thickening of the jejunum which indicated a pathology of lymphoma or adenocarcinoma.

  • Fig. 2. Endoscopic finding. A large cancerous lesion with friable bleeding mucosa was found in the proximal jejunum that almost obstructed the bowel.

  • Fig. 3. PET scan finding. It revealed that the jejunal mass showed intense hypermetabolism. There were no other abnormal metabolic lesions.

  • Fig. 4. Gross finding of the jejunal segmentectomy specimen. There was 9.0×5.5 cm mass involving the proximal jejunum.

  • Fig. 5. Pathologic finding. (A) Well differentiated adenocarcinoma extended to the muscle layer and periintestinal adipose tissue of jejunum (H&E,×12.5). (B) Proliferation of atypical glands with irregular contours. The adenocarcinoma invaded the adjacent tissue with necrosis (H&E, ×100).
