Abstract:
Objective To investigate the clinical manifestations, histopathological patterns and causes of misdiagnosis of primary malignant tumor in small intestine (PMTSI). Methods The clinical data of 90 cases of PMTSI confirmed by pathology admitted from 1981 to 2002 in our hospital were retrospectively analyzed. Results The main pathological patterns of PMTSI were adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma. The common clinical manifestations were abdominal pain, anemia and hemorrhage, jaundice, weight loss and intestinal obstructions. Preoperative diagnosis rate was 22.2%(20/90). It was easily misdiagnosed as other digestive tract diseases and pelvic disorders. Preoperative misdiagnosis rate was 77.8%. Conclusions The main pathological patterns of PMTSI are adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma.Its clinical manifestations and diagnostic examination methods are not good enough, which usually leads to misdiagnosis ,so attention must be paid.
