後腹膜脱分化型脂肪肉腫の一例  [in Japanese] RETROPERITONEAL DEDIFFERENTIATED LIPOSARCOMA : A CASE REPORT  [in Japanese]

Abstract

後腹膜腫瘍は比較的稀な疾患であるが,その中でも脱分化型脂肪肉腫は後腹膜腫瘍全体の約0.5%と極めて稀である.今回我々は典型的な画像所見を呈した脱分化型脂肪肉腫の1例を経験したので報告する.症例は64歳,女性.左側腹部痛を主訴に当院を受診腹部超音波検査,腹部CT検査にて左後腹膜腔に脂肪領域を含む最大径12cmの大きな充実性の腫瘤を認めた.後腹膜腔脂肪肉腫の診断にて腫瘍摘除術および左腎摘除術を施行した.病理組織検査にて腫瘍は高分化の脂肪肉腫に混在して,脱分化したと思われる線維肉腫様の腫瘤が形成されており,脱分化型脂肪肉腫と診断された.

A 64 year-old female visited our outpatient clinic with left dull flank pain. The ultrasonography and CT scans showed the large solid mass in 12 cm in maximum diameter, containing large area of fatty element, in the left retroperitoneal space. Under the diagnosis of retroperitoneum liposarcoma, the mass and left kidney was completely removed. Pathological examination revealed the dedifferentiated liposarcoma which contained the distinct two patterns of well differentiated lipoma and dedifferentiated fibrotic sarcomatoid tissue.
