The patient was a 27-year old female who complained of dyspnea. CT scan revealed a solid mass in the anterior mediastinal region. The tumor was removed on June 10, 1992, through a longitudinal sternal incision. Histological examination showed massive thymic hyperplasia. Massive thymic hyperplasia is very rare in adults. Dyspnea was alleviated postoperatively.
