ABSTRACT
Sclerosing stromal tumour is a rare benign usually unilateral ovarian tumour. We present three cases of this neoplasm in young females, including one bilateral case. All tumours were composed of cellular areas forming pseudolobular patterns, as well as vascular, fibrous, and myxoid areas. The characteristic feature of tumours was cellular heterogenity. All tumours revealed negative immunostaining for cytokeratin, and intense positive immunostaining for vimentin, and smooth muscle actin. Immunostaining for desmin and progesterone receptors was weakly positive.

Cystic nephroma is rare, but its coexistence with renal cortical adenoma is unique and has never been reported previously. We present a unique case of simultaneous occurrence of cystic nephroma and renal cortical adenoma in 47-year-old man. Both tumours were situated in the lower pole of the right kidney and were clinically asymptomatic.
