[A case of thymic squamous cell carcinoma successfully treated with curative resection]

A case of rare thymic squamous cell carcinoma was reported. A 46-year-old female was admitted to our hospital because of an abnormal shadow on chest X-ray. Chest CT showed anterior mediastinal tumor and histological diagnosis of squamous cell carcinoma was made by needle biopsy under CT guide. Esophagus and lung were no abnormal findings, we thought the primary region was thymus. On mid-sternotomy, anterior mediastinal tumor was resected with thymus, right phrenic nerve and pericardium, however it was not direct invasion to heart, great vessels, lung and chest wall. Resection of peripheral fatty tissue and dissection of mediastinal lymph nodes as much as possible, it was not capsular invasion and mediastinal lymph nodes metastasis and complete curative resection was able to perform. Additional radiation therapy was done, post-operative course was uneventful.
