N2 - Most neoplasms arising from the thymic epithelium are considered to be 'thymomas', which are composed of cytologically benign, neoplastic epithelial cells and non-neoplastic lymphocytes. In contrast, thymic epithelial neoplasms displaying cytologically malignant features have recently been classified as thymic carcinomas of various types of histology (1-6). However, primary thymic adenocarcinoma is extremely rare and only four cases of it have been reported in the literature (7). We report a rare case of primary thymic adenocarcinoma of 4-year complete remission with concurrent chemoradiotherapy followed by surgery. A 61-year-old Japanese man was referred to us complaining of facial edema and general fatigue. Computed tomography scans revealed a huge mass in the anterior mediastinum obstructing the superior vena cava. He was diagnosed with thymic adenocarcinoma on needle biopsy. He was treated with induction chemoradiotherapy consisting of cisplatin, 5-FU and concurrent thoracic radiation, which yielded a partial response. He then underwent surgical resection of the remaining mass. However, Pathologic examination of the resected mass revealed no malignant cells. The patient is doing well without symptoms or signs of relapse 53 months after diagnosis.
