Teratoid Wilms' tumor is a rare variant of Wilms' tumor (WT) which mostly occurs in paediatric age group. We are describing here a rare case of renal mass with teratoid histology in an adult female. The tumor was removed by enucleation. Grossly, the removed tumour was well-encapsulated homogeneous mass measuring 2 x 3 cm. On microscopy triphasic patterns of WT and prominent heterologous components were seen, including rhabdomyoblasts, bone, cartilage, and various types of mature epithelium. This is probably third reported case of a teratoid WT occurring in an adult kidney.
