Introduction Adult granulosa cell tumor (AGCT) accounts for 5% of all ovarian cancers.
Their histopathologic features are relatively nonspecific, resulting in misdiagnosis, a problem that has not been well characterized.
Objective To study clinicopathological features and evolutionary characteristics of AGCT of the ovary
Methods This is a retrospective study of ten cases of AGCT of the ovary, collected in the pathology department of the M. Slim Hospital over a period of 16 years (2002 to 2017). Evolutionary data were collected from medical records of the gynecology department of the same hospital.
Results The average age of our patients was 58 years. Pelvic ultrasound allowed objectifying the ovary tumors in 8 cases and CT scans in 2 cases. All tumors were unilateral and confined to the ovary, without rupture.
Seven patients were treated with unilateral adnexectomy and 3 with a hysterectomy and bilateral adnexectomy.
Eight tumors were encapsulated with a smooth lobulated surface. Seven tumors were solid and 3 solid and cystic.
Tumor size varied between 8,5 and 25 cm. The histopathological study allowed us to make the diagnosis in 6 cases. In 4 cases, an immunohistochemistry study was made to confirm the diagnosis.
No recurrence was noted for all cases with a median follow up of 5 years.
Conclusion Although the course of AGCT of the ovary is often indolent, an unpredictable disease course with recurrence rates up to 50%. Then, an attentive examination of tumor specimens must be done, evaluating prognostic factors as the stage, nuclear atypia, and tumor size.
