Abstract

症例1:24歳男.左側陰嚢内腫瘍は, 精巣・精索等の陰嚢内容物と明らかに分離しており, 腫瘍摘除術を施行した.病理組織診断は脂肪肉腫・類粘液型であり, 手術後21ヵ月再発を認めていない. 症例2:66歳男.左側陰嚢内腫瘍は, 精索より発生しており, 高位精巣摘除術を施行した.病理組織診断学的には脂肪肉腫・分化型であり, 手術後40ヵ月再発を認めていない

Liposarcomas in the scrotum are relatively rare and only 40 cases have previously been reported in Japan. The inside wall of the scrotum is an unusual origin and we report here two cases arising at this site that have been followed for 21 and 40 months, respectively, after surgical resection. Case 1: the patient was a 24-year-old male who noticed a left intrascrotal mass which was histologically demonstrated to be a myxoid type liposarcoma. Case 2: the patient was a 66-year-old male who had the complaint of a left intrascrotal swelling. He underwent radical orchiectomy and histologic examination of the resected tumor revealed a well-differentiated type of liposarcoma. These two cases are the 41st and 42nd intrascrotal liposarcomas reported in Japan.
