小腸平滑筋芽細胞腫は極めて稀な疾患である.今回,小腸平滑筋芽細胞腫術後に腹膜播種再発を認めた1例を経験したので報告する.症例は70歳女性. 2年前に前医で下血発症により小腸腫瘍の診断で空腸切除術施行.術後病理診断は平滑筋芽細胞腫であった.リンパ節転移や他臓器浸潤は認めなかった.核分裂像は2~3/10視野であった.今回,他疾患で当院入院.腹部腫瘤を触知し,腹部CT上腹腔内に累々とした腫瘍が認められた.開腹術施行するに,腹膜播種と考えられる多数の腫瘍を腹膜,大網,腸間膜に認めた.根治的切除は不可と判断し,可及的切除で閉腹した.術後病理検査より腹膜播種再発と診断した.小腸平滑筋芽細胞腫について本邦報告例を集計し検討した.

Leiomyoblastoma of the small intestine is a rare disease. We report a case of peritoneally disseminated recurrence occurred 2 years after an operation for a leiomyoblastoma of the jejunum.<br>A 70-year-old woman was admitted to the hospital because of other disease. Two years prior to this admission, she had undergone a partial jejunectomy due to leiomyoblastoma, when no lymph node metastasis nor invasion to other organs was revealed. Histologically, mitotic figures of the tumor were seen two or three per ten high-power fields. That was diagnosed as low grade malignancy. In this admission, she was detected the abdominal tumor on paltation. Bulky tumors were showed in the abdominal cavity on an abdominal CT scan. An exploratory laparotomy was performed. We judged that radical resection was impossible and removed those tumors as much as possible. These tumors were diagnosed histologically as peritoneally disseminated recurrence of the intestinal leomyoblastoma.<br>This paper also presents a review of 31 cases in the duodenum and 47 cases in the jejunum and ileum including this case which have been reported in Japan.
