嚢胞状腫瘤の形態を呈し,穿孔にて発症した小腸平滑筋腫瘍の1例を経験したので報告する.症例は47歳,女性.右下腹部痛,発熱を主訴に来院.右下腹部に圧痛,反跳痛を認め,腹部USでは子宮の右側に内部エコーが不均一な7cmの腫瘤を認め,腹部CTでは辺縁が造影にて強調される嚢胞状腫瘤で内部にはガス像を認めた.右卵巣嚢腫の茎捻転を疑い緊急手術を施行.上部空腸に嚢胞状腫瘤を認め,壁は破裂し周囲には膿の貯留を認めた.腫瘤を含めて約10cmの小腸を切除した.摘出標本では70×63mm大,壁厚が2mmの嚢胞状腫瘤で内腔には壊死組織を認め,小腸との交通を認めた.病理組織学的検査では嚢胞壁部に紡錘型細胞の錯走を認め, SMA染色陽性で小腸平滑筋腫瘍と診断された.

We experienced a case of smooth muscle tumor of the small intestine in a shape of cystic tumor presenting with perforation.<br> A 47-year-old woman was seen at the hospital because of a right lower quadrant pain and fever. There were tenderness and rebound tenderness in the right lower abdomen. Abdominal ultrasonography revealed a 7cm tumor with enheterogenous internal echo in the right side of the uterus. Abdominal CT visualized a cystic tumor with enhanced margin and gas in the tumor. Torsion of the right ovarian cyst was suspected and an emergency operation was performed. At laparotomy, a cystic tumor was found in the upper jejunum with the ruputerd wall and there was accumulation of pus in the vicinity of the tumor. About 10cm of the small intestine including the tumor was excised. The excised specimen revealed a 70×63mm cystic tumor with the wall thickness of 2mm, necrosed tissue in the lumen and a communication with the small intestine.<br> Histopathologically, interlacing spindle cell was confirmed in the cyst wall, and SMA staining was positive. The definite diagnosis of smooth muscle tumor of the small intestine was made.
