Early-stage granulosa cell tumor with pelvic recurrence and lung metastasis 16 years later: A case report and review of the literature

ObjectiveOnly a few cases of early-stage ovarian granulosa cell tumor (GCT) with lung metastasis have been previously documented in the literature. We present a case of stage IA adult-type ovarian GCT with late pelvic recurrence and lung metastasis and review the relevant literature.Case reportA 71-year-old female who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy for an ovarian GCT in her early 50s presented with pelvic recurrence 16 years later. Lung metastasis was accidentally discovered during a preoperative computed tomography scan of the pelvic tumor. The patient received surgical resection and adjuvant chemotherapy. She remains alive and healthy without evidence of disease after 12 months of follow up.ConclusionThis case illustrates the importance of long-term follow-up for early-stage GCTs. It also highlights the requirement of extended examination for possible extra-abdominal/pelvic tumors.
