Ovarian steroid cell tumors, not otherwise specified: analysis of nine cases with a literature review

BMC Endocr Disord. 2022 Nov 1;22(1):265. doi: 10.1186/s12902-022-01170-9.


Background: Ovarian steroid cell tumors (SCTs), not otherwise specified (NOS), are rare, with few large studies. The purpose of this study was to analyze the clinical features, prognosis, and treatment choices for these patients of different age groups.

Methods: This was a retrospective study. We identified nine cases of ovarian steroid cell tumor, not otherwise specified, confirmed by post-operative histopathological examination, and analyzed clinical features, surgical procedures, and follow up outcomes. We also reviewed cases reports of ovarian steroid cell tumors, not otherwise specified.

Results: A total of nine cases were included. The age range was 9-68 years (mean, 41.89 ± 19.72 years). Clinical features included virilization, amenorrhea, abdominal pain, vaginal bleeding, isosexual precocious puberty, Cushing's syndrome, and abnormal weight gain with elevated testosterone levels. The follow up interval ranged 5-53 months and no recurrence was observed.

Conclusion: Ovarian steroid cell tumors covered all age groups, with manifestations of androgen excess. Younger patients appeared to have a more favorable prognosis, which provided more opportunities for these patients to pursue treatment options that will preserve reproductive function.
