[A case of invasive thymoma with retroperitoneal recurrence].
A case of invasive thymoma with retroperitoneal recurrence is reported. A 55-year-old man with invasive thymoma (Masaokas classification, Stage IVa) underwent thymo-thymectomy, partial resection of left upper lobe, resection of phrenic nerve and partial resection of parietal pleura on March 14, 1989. Histological findings revealed thymoma with predominantly lymphocytic type. Two years after the operation, the tumor of retroperitoneal recurrence was discovered in abdominal CT. This retroperitoneal tumor was huge in size (16 x 12 cm) and extended into posterior mediastinum via aortic hiatus. The patient underwent resection of tumor through thoracotomy and laparotomy on April 23, 1991, after two cycles of chemotherapy. Histological findings revealed thymoma with predominantly lymphocytic type. This case was rare among patients with recurrence of thymoma as far as the site of recurrence is concerned.
