[Clinico-morphological signs of hormone-producing ovarian tumors]

Apparent signs of hormonal activity were observed in 65.3% of patients with hormone-producing ovarian tumors of different histology. Feminization was evident in 69.1% of cases of granulosa-stromal cell tumors: it was most often seen in patients with mixed theca-granulosa cell tumors (86.2%) but was least frequent in those with Brenner's tumor (22.2%). The occurrence of proliferative lesions of the uterus such as hyperplasia of the endometrium, cervical canal polyps and uterine myoma (81.8%) was higher in patients with granulosa-stromal cell tumors, too, the highest rate being observed for cases of mixed theca-granulosa cell tumors (93.1%) whereas the lowest--for patients with Brenner's tumor (27.8%). Various clinical signs of masculinization were most often seen in cases of androblastoma (79.2%) whereas the proliferative disorders in that group were rare (12.5%). As a result, the authors placed mixed theca-granulosa cell, theca cell, granulosa cell tumors and Brenner's tumor in the order of decreasing feminizing activity. In the granulosa-stromal cell tumor subgroup, masculinization was most often observed in granulosa cell tumor patients (12.1%).
