Extremely late recurrence of adult granulosa cell tumor in the retroperitoneal space 27 years after surgery manifesting as a liver tumor

A 72-year-old woman was referred to a liver tumor treatment center due to significant enlargement of the liver tumor in segment six, measuring 110 × 110 × 85 mm in size.The tumor was observed for six months and was described via magnetic resonance imaging as a lymphatic cavernoma.The patient underwent hysterectomy with appendage amputation 26 years ago due to endometrial cancer and subsequently underwent chemotherapy.At that time, the patient had no comorbidities, no symptoms, or any major health issues.The patients were consulted at a multidisciplinary team meeting, and a decision regarding the possibility of resection was made.Biopsy was contraindicated due to an extreme risk of bleeding.The magnetic resonance imaging results are presented in Figure 1.
