The authors describe the case of a 50-year old patient with a hypertension, who was sterile and obese. She presented with the clinical diagnosis of „malignant corporal polyp“. On microscopical examination we found an endometroid adenocarcinoma of the endometrium with focal squamous differentiation associated with bilateral stromal hyperthecosis of the ovaries. Stromal hyperthe- cosis of the ovaries is often associated with oestrogen and androgen hypersecretion (virilismus), obesity and hypertension. Owing to these well known features we assume that the endometroid adenocarcinoma of the uterus was caused by ovarian hyperthecosis.

        Key words: ovarian stromal hyperthecosis, endometroid carcinoma
