十二指肠上皮样平滑肌瘤临床罕见。最近我院诊治一例报道如下。男,49岁。因右中腹部包块2月余,无自觉症状,于1987年3月4日以“腹部包块”住院。3年前曾上消化道大山血,胃镜检查提示“胃炎”。 Duodenal epithelioid leiomyomas are rare clinically. Recently, one case has been reported in our hospital. Male, 49 years old. Due to more than two months of mass in the right midriff, there was no subjective symptom. On March 4, 1987, the patient was hospitalized as an abdominal mass. Three years ago, he had had blood in the upper digestive tract. His gastroscopy prompted gastritis.
