腎線維肉腫，腎結石，後腹膜脂肪腫を合併せる1例

THE COMBINATION OF RENAL FIBROSARCOMA, STAGHORN CALCULUS AND RETROPERITONEAL LIPOMA IN A WOMAN

Ⅰ．緒言

　我々は腎線維肉腫，腎結石，後腹膜脂肪腫を合併せるきわめてまれな症例を経験したので，この症例を報告するとともに，1965年12月まで本症例を含めて，腎肉腫75例，後腹膜脂肪腫39例についていささかの統計的考察を加えてみたい。

A 43 years old female visited our clinic with the chief complaint of right back pain and swelling of the epigastric region. The diagnosis of right renal tumor with calculus was made by intravenous urography and right nephrectomy was performed. During surgery, retroperitoneal tumor was found to be coexisting with the above. Pathological examination comfirmed the diagnosis of right renal fibrosarcoma with stag-horn calculi and retroperitoneal lipoma. Postoperative course was uneventful.
