✦ Synopsis

The histologic, morphometric, immunohistochemical, and ultrastructural study of a malignant Brenner tumor in a postmenopausal women presenting with vaginal bleeding is described. A comparison with transitional cell carcinomas is made, and the use of morphometry in grading the urothelial-like epithelium in malignant Brenner tumors is suggested. High preoperative urinary estrogen, low serum lutehizing hormone (LH) and follicle-stimulating hormone (FSH) levels and histologically confirmed atypical endometrial hyperplasia suggested a hyperestrogenism. The reduction in urinary estrogen and the increase in serum LH and FSH after tumor removal and the presence of aromatase activity detected in tumor microsomes confirmed that the tumor was synthesizing estrogen. Estrogen receptors were undetectable both by biochemical and histochemical analysis in the tumor.
