Lipomas of the gastrointestinal tract are extremely rare, slow-growing and most often asymptomatic tumours. They are composed of highly differentiated fat cells surrounded by a fibrous capsule. Tumours larger than 2 cm can produce symptoms of abdominal pain and discomfort or cause anaemia due to ulceration and bleeding, or intestinal obstruction due to intussusception. This is a case report of a 73-year-old man with a bleeding duodenal lipoma situated at the papilla duodeni major which caused difficulty in the diagnostic process, and the endoscopic visualization raised suspicion of cancer of the papilla.
胃肠道脂肪瘤极为罕见，生长缓慢，且大多无症状。它们由高度分化的脂肪细胞组成，周围有一层纤维包膜。直径大于2厘米的肿瘤可产生腹痛和不适症状，或因溃疡和出血导致贫血，或因肠套叠引起肠梗阻。本文报告一例73岁男性患者，其十二指肠大乳头处的脂肪瘤出血，给诊断过程带来困难，内镜检查结果引发了对乳头癌的怀疑。
