Renal mixed epithelial and stromal tumor: case report

Benign mixed epithelial stromal tumor of the renal pelvis with exophytic growth: case report

BACKGROUND Mixed epithelial and stromal tumor (MEST) is a distinctive benign composite neoplasm of the kidney predominantly seen in females mostly in the perimenopausal period. Although these tumors are known to arise from renal pelvis, our case was distinct in that it had no intrapelvic component growing in exophytic fashion. CASE REPORT A 35 year old female patient presented to us with vagu...

Mixed Epithelial and Stromal Tumor of the Kidney – A Case Report

A 45-year-old woman had gross hematuria without flank pain for two weeks. She visited our hospital and a renal echo showed a heterogenous mass on the left kidney. Abdominal computed tomography showed a multicystic tumor, about 7 cm, on the left renal pelvis and the proximal ureter. The tumor was enhanced after contrast injection. Ureteroscopy showed an intraluminal polypoid tumor. Cystic renal ...

Mixed Epithelial and Stromal Tumor of the Kidney : A Case Report

The descriptive term "mixed epithelial and stromal tumor of the kidney" was recently proposed for a group of renal tumors characterized histologically by a mixture of stromal and epithelial proliferation. It is a rare benign neoplasm of the kidney which has been reported under various names such as adult type mesoblastic nephroma or others. We report a case of mixed epithelial and stromal tumor...

[A case of mixed epithelial and stromal tumor (MEST) of the kidney monitored as angiomyolipoma (AML) : a case report].

A 32-year-old woman presented with left abdominal pain. Intratumoral hemorrhage within a renal angiomyolipoma (AML) was suspected and embolization was performed. However, the patient declined surgery and was thus kept under observation. During the next 5 years, the tumor increased in size, and upper left abdominal pain appeared. Therefore, left radical nephrectomy was performed. The histopathol...
