腎線維腫の1例

FIBROMA OF THE KIDNEY:REPORT OF A CASE

緒言

　腎の良性腫瘍は上皮性，非上皮性を問わずきわめてまれなものであり，ほとんどの場合臨床症状を呈することなく，病理解剖などで発見されることが多い。ことにこれら良性腫瘍のうち，腎線維腫として臨床的に治療された例は文献上少数例をみるにすぎない。著者は最近，腎線維腫の1例を経験したのでここに報告するとともに，文献上よりみた統計的考察を加える。

A 38-year-old housewife was admitted to Kooseiren Chuo Hospital on Aug. 13, 1977 with a com-plaint of a palpable mass on the right flank. Intravenous urography revealed the lateral displacement of the whole right renal pelvis by a large mass. Retrograde pyelography comfirmed the same finding. With a tentative diagnosis of the right renal tumor, the right kidney was removed under general anesthesia on Aug. 22, 1977. The kidney, including two tumor masses, measured 15 x 12 x 7 cm, weighted 620 g, each tumor being 10 x 8 x 4.5 cm and 6. 5 x 5.5 x 5 cm in size. Cut surface of the tumors was grayish-white and elastic hard.
