Ovarian sclerosing stromal tumor mimicking malignancy: case series and literature review

Sclerosing stromal tumors (SST) are rare ovarian neoplasms that often appear as solid unilateral tumors of the ovary with no specific clinical or radiological presentation. The definitive treatment is surgical removal.

Our article presents four cases of female patients with sclerosing stromal ovarian tumor with clinical characteristics mimicking malignant ovarian lesions. Interestingly, two of our cases had elevated levels of inhibin B. All patients were treated with surgery (oophorectomy) and had no disease recurrence.

Tumors’ macroscopic features are usually non-specific and often suggestive of possible malignancy, therefore diagnosis is always based on histopathological report.
