[Thymoma with Extensive Necrosis:Report of a Case]

Abstract

A 65-years-old female was admitted to our hospital for treatment of fever and chest pain. Contrast-enhanced computed tomography (CT) revealed an anterior mediastinal tumor with a thickened wall, and right pleural effusion. Ten days after antibiotic therapy, the fever, chest pain and pleural effusion disappeared. Thymectomy was performed to confirm the diagnosis. Histopathologic diagnosis was type B2 thymoma with extensive necrotic area, Masaoka's stageⅠ. No recurrence has been observed for approximately two years since the surgery. Thymomas have a variety of pathological features such as cystic and hemorrhagic changes and necrosis. However, thymomas with extensive necrosis are very rare. We presented this case with a review of the literature.
