| Abstract: | 60歳代男。患者は右陰嚢内無痛性腫瘤を主訴とした。40歳代から腫瘤が触知され、2～3ヵ月前から増大傾向を認めたため受診となった。血液検査、腫瘍マーカー、尿検査では異常は認められなかったものの、MRIでは右精索に沿って腫瘤を認め、腫瘤尾側にも脂肪の信号を示す部分があった。高分化型の脂肪肉腫が疑われ、腫瘤は細胞成分に富む腫瘍が2次的に発生したものと推測された。高位精巣摘除術に準じて手術を施行したところ、腫瘤周囲の癒着はなく腫瘤、脂肪性病変、精巣を一塊に摘除し得た。術後経過は順調で、1年4ヵ月現在、再発は認められていない。尚、本症例はlipoma-like type とscrelosing typeが並存しており、炎症性成分は主にscrelosing typeに認められた。発生部位としては精巣実質に浸潤を認めず、精索由来と考えられた。
Well-differentiated inflammatory liposarcoma is an unusual variant of liposarcoma, accounting for only about 2% of all liposarcomas. We report a case occurring in a 68-year-old male. An elastic soft mass, apart from the testis, was palpated in the right scrotum. Magnetic resonance imaging showed a 4 cm mass along the right spermatic cord. High orchiectomy was performed. Histologically, the mass was composed of lymphocytic aggregates, and paucicellular stroma with multinucleated cells. The adjacent lipoma-like lesion was clearly defined, and the mass was pathologically diagnosed as well-differentiated inflammatory liposarcoma. |
