A rare benign ovarian tumour.

Area of Science:

• Gynecologic Oncology
• Reproductive Endocrinology
• Surgical Pathology

Background:

• Sclerosing stromal tumour (SST) is an exceptionally rare ovarian neoplasm, comprising 6% of sex cord-stromal tumours.
• Typically diagnosed in women during their second and third decades of life.
• Common symptoms include pelvic pain, a palpable mass, or menstrual irregularities.

Observation:

• A 20-year-old woman presented with mild pelvic pain and normal laboratory results.
• Imaging revealed a large right adnexal mass, suggestive of an ovarian sex cord tumour.
• The patient underwent a right salpingo-oophorectomy for diagnosis and treatment.

Findings:

• Histopathological examination confirmed the diagnosis of Sclerosing Stromal Tumour (SST) of the ovary.
• The review emphasizes characteristic pathological and imaging features of this rare benign lesion.
• SST management often involves conservative surgical approaches.

Implications:

• Understanding the typical presentation aids in early diagnosis of rare ovarian tumours.
• Conservative surgery is feasible for benign lesions like SST, preserving ovarian function.
• This case contributes to the literature on rare sex cord-stromal ovarian tumours.
