An Adult Granulosa Cell Tumor that Disseminated to the Diaphragm 10 Years after Oophorectomy—A Case Report—

Abstract

A 72-year-old woman underwent endoscopic choledocholithotomy for choledocholithiasis. Computed tomography scanning also confirmed a cystic mass in liver S8. Although bile juice cytology showed no inflammatory change or malignancy,the mass had enlarged gradually. Aspiration cytology suggested hepatic cystadenoma. Thus, since the findings could not rule out the possibility of a malignant liver tumor, segmentectomy was scheduled. Intraoperatively, the tumor was diagnosed as originating from the right diaphragm without involving the liver. However, histopathological examination confirmed the diagnosis of disseminated AGCT. Later, it was determined that the patient had undergone oophorectomy for an AGCT 10 years earlier. It is sometimes difficult to distinguish a disseminated tumor from the liver or a tumor of the diaphragm. Moreover, it is essential to take a detailed history when the patient has a past operative history of ovarian tumors.
