AFP-producing sertoli-leydig cell tumor of the ovary

Archives of Gynecology, 1985
A tumor of the right ovary in a 21-year-old single woman is reported. Secondary amenorrhea, hirsutism, acne and deepening of the voice were associated with the tumor.

Arrested puberty associated with a Sertoli-Leydig cell tumor

American Journal of Obstetrics and Gynecology, 1985
Androgen-producing ovarian tumors are rarely recognized as a cause of delayed or arrested puberty, despite their frequent association with secondary amenorrhea in the older patient. A case is discussed of a Sertoli-Leydig cell tumor in an 18-year-old girl resulting in arrest of breast development and primary amenorrhea.

Analysis for Steroid Production of a Sertoli-Leydig Cell Tumor

Gynecologic Oncology, 1994
Sex cord stromal tumors of the ovary can be characterized by the production of virilizing steroid hormones. The authors present a case of a poorly differentiated Sertoli-Leydig cell tumor in which ascitic fluid was found to have a high concentration of androgenic hormones and precursors from the delta steroid pathway (17-OH progesterone, testosterone ...

Ovarian Sertoli-Leydig cell tumors. A retrospective MITO study

Gynecologic Oncology, 2012
To evaluate clinicopathologic features and to investigate the outcome of patients with ovarian Sertoli-Leydig cell tumors (SLCTs).Data concerning 21 patients treated in 11 MITO centers were retrospectively reviewed.Median age was 37 (range 16-76).

Ovarian Sertoli-Leydig Cell Tumors

Obstetrical & Gynecological Survey, 1980
Ovarian Sertoli-Leydig cell tumors are rare, most of them being endocrinologically active and causing virilization. Their histogenesis and nomenclature are still under discussion. Six such tumors were identified in the Laboratory for Histopathology of the University Women's Hospital, Zürich. The clinical data as well as the macroscopic, microscopic and
