ABSTRACT: Mixed epithelial and stromal tumor of the kidney (MESTK) is a recently described rare neoplasm. Malignant transformation, recurrence and metastasis are rare, therefore histopathological distinction from other renal neoplasms, especially from renal cell carcinoma is important. Histologically the tumor is composed of biphasic components including cysts and tubules embedded in the spindle cell stroma. We report a case of a MESTK in 60-year-old postmenopousal woman who presented with an incidental solid renal mass but no urinary complaint.
