Sertoli-Leydig tumors of the ovary. A clinicopathologic study of 64 intermediate and poorly differentiated neoplasms.


The clinical and pathologic features of 64 Sertoli-Leydig tumors of the ovary with intermediate and poor differentiation were studied. The neoplasms occurred mainly in young women. Fifty-four percent of the patients presented with clinical evidence of a hormonally active tumor, and 38% were virilized. The remaining 46% had nonspecific symptoms. Sixty-two patients had tumors confined to one ovary at operation (Stage Ia), while only two patients presented with pelvic metastases (Stage III). The prognosis was generally favorable; the 5- and 10-year actuarial survival rates were 92%. Unilateral salpingo-oophorectomy was effective treatment for Stage Ia Sertoli-Leydig tumors in young women. Microscopically, 44 of the neoplasms were of intermediate differentiation and 20 were poorly differentiated. Heterologous elements (mucinous epithelium, striated muscle, cartilage) were present in 16 neoplasms. The pathologic features that correspond with development of metastases were poor differentiation, the presence of heterologous mesenchymal elements, frequent mitotic figures in stromal cells, and rupture of the neoplasm.
