Thymic metastasis of ovarian cancer 33 years after primary surgery

Abstract This report describes a case of extremely late recurrence of thymic metastasis following radical resection of ovarian cancer. Chest computed tomography demonstrated anterior mediastinal nodules with a smooth marginal area in a 56-year-old female who had undergone an oophorectomy for ovarian cancer 33 years prior. Imaging findings suggested a thymic epithelial tumor, thus a partial thymectomy was performed. Histopathological results led to a diagnosis of thymic metastasis of ovarian cancer. In patients with a medical history of ovarian cancer, thymic metastasis should be considered as a differential diagnosis for the presence of a thymic tumor.
