Granulosa tumors of the ovary in children: a clinical and pathologic study of 32 cases.
Granulosa tumors in children differ histologically from those occurring in adults. Of 32 neoplasms occurring in girls 16 years of age or younger, 26 were juvenile granulosa tumors and three were cystic granulosa tumors; only three neoplasms resembled typical adult granulosa tumors. The juvenile granulosa tumor differs from the typical adult form in that it is composed of larger cells and has luteinization of its cellular components. Two-thirds of the patients had endocrine abnormalities. Fifteen of 20 premenarcheal patients had isosexual precocious pseudopuberty. Of the 12 postmenarcheal girls, seven had menstrual abnormalities and two of the seven were virilized. All 32 patients had Stage Ia tumors. The clinical outcome was generally favorable since only two of 26 patients with follow-up developed a recurrence. Unilateral salpingo-oophorectomy is appropriate treatment for girls with Stage Ia granulosa tumors; 23 of 25 patients treated by unilateral salpingo-oophorectomy were well without recurrence at last contact.
