Ovarian tumor with functioning stroma

Sertoli‐Leydig cell tumor ‐ a rare androgen secreting ovarian tumor in postmenopausal women: case report and review of literature

“…• residual sex cords from the indifferent primitive gonad, originating in the coelomic tissue • mesenchymal cells of the cortical and medullar primitive gonad (undifferentiated multipotent endocrine stroma) • primitive ovarian medulla from the mesonephric mesenchyme In most cases it is accepted that the tumor originates from the ovarian stroma in ovotestis [5]. The mammalian sex determination and differentiation of the gonads is under the control of the sex-determining gene, Sry, on the chromosome Y.…”

Tumor de células esteroideas de ovario: Reporte de un caso.

“…Además es necesario realizar otros exámenes como ecografía y tomografía de adrenales y de ovarios, así como resonancia magnética (14,18,19). La tomografía puede identificar una masa adrenal tan pequeña como de 1,5cm (7).…”

Primary Carcinoid Tumor of the Ovary: MR Imaging Characteristics with Pathologic Correlation

“…Various ovarian tumors with estrogenic manifestations attributable to functioning stroma have been reported. 11 Tanaka and associates reported 2 cases, a carcinoid tumor and a mucinous cystadenoma, with functioning stroma that appeared as multilocular cystic masses with varying signal on MR. 12 Any ovarian tumor, including carcinoid tumor, could have hormonal activity and mimic ordinary hormone-producing tumors. 12 It is important to diagnose carcinoid tumors before extraovarian progression because organ-conˆned, early stage ovarian carcinoid tumors have good prognosis and surgical excision is curative.…”
