BACKGROUND:

Ovarian stromal hyperthecosis is a rare ovarian androgenizing tumor that can manifest as hyperandrogenism, endometrial carcinoma, obesity and hypertension. Only a few case reports and small case series are found in the literature.

CLINICAL CASE:

20-year-old patient with continuous vaginal bleeding, hirsutism, clitoromegaly, and android implantation of pubic and facial hair. Ultrasonography of the right ovary showed a solid lesion inside the ovary. Elevated concentrations of free testosterone, testosterone and hydroxyprogesterone. An ovarian androgenizing tumor was suspected. A laparoscopic right salpingo-oophorectomy was performed. The pathology report was ovarian parenchyma with extensive nests of luteinized stromal cells with stromal hyperplasia. Diagnosis: stromal hyperthecosis.

CONCLUSION:

In the coexistence of signs of virilization, alteration in the regularity and frequency of the menstrual cycle, with high concentrations of androgens and an ovarian tumor lesion in the ultrasound study, ovarian stromal hyperthecosis should be suspected. The treatment of choice is surgical resection of the affected ovary. Due to the low malignant potential of these lesions, laparoscopic access can be considered.
