Abstract
- A 47-years-old woman visited our hospital with the chief complaint of painless gross hematuria. IVP, RGP and CT showed a soft tissue tumor in left renal pelvis. Left radical nephrectomy was performed. The pathological diagnosis was leiomyoma. Leiomyomas may originate from any anatomic location of smooth muscle in the genitourinary system but are uncommon neoplasm, especially leiomyomas of the renal pelvis are very rare tumors. To date 5 cases diagnosed by histological appearance only have been reported. All 5 tumors were composed of spindle cells that resembled mature smooth muscle cells. The preoperative diagnosis of leiomyoma of renal pelvis is very difficult because of the absence of the characteristic diagnostic signs, and the only definite method to distinguish between a leiomyoma and other renal tumor is histological evaluation. We herein report the sixth case of leiomyoma of renal pelvis in a 47-years-old woman, with a brief review of literature.
