Abstract

We herein present 2 cases of mediastinal teratoma with intrapulmonary perforation, and its diagnostic pitfall in its variable manifestation.<BR>Case 1: A 35-year-old female presented with a complaint of fever and a solid anterior mediastinal tumor was detected on chest computed tomogram (CT). Definitive diagnosis was not obtained, despite several biopsies to rule out malignancy, until surgical extirpation was achieved . The resected specimen finally disclosed a mature teratoma with intrapulmonary perforation.<BR>Case 2: A 49-year-old female who received medication for chronic hemoptysis was found to have an abnormal shadow on chest X-ray. A chest CT showed a cystic mass with a thick wall in the anterior mediastinum, suggestive of mature teratoma. A needle biopsy did not reach a histological diagnosis, but the mass was confirmed to be mature teratoma with intrapulmonary perforation following surgical resection . In some mediastinal teratoma, there are cases that shows very slight symptoms, although they are actually perforated into the lung. So, as a diagnosis of teratoma, we should know its variable manifestation.
