Giant Renal Mixed Epithelial and Stromal Tumour in A Young Female: A Rare Presentation.

Mixed epithelial and stromal tumour of the kidney (MESTK), is a rare kidney tumour. About 100 cases so far have been reported in the literature. Although MESTK mostly presents in perimenopausal age group some rare cases in young females have been reported. We report a rare presentation of a 25 cm size giant MESTK arising from the left kidney in a young female in the absence of any clinically detectable hormonal abnormalities and successfully managed by nephron-sparing surgery.
