title: A chondrosarcoma in the anterior mediastinum mimicking a thymoma.
abstract: A chondrosarcoma in the anterior mediastinum is a rare finding with a relatively good prognosis. We describe a case of a 75-year-old man with a 2-year history of neck discomfort and weight loss. Imaging showed a homogenous tumor with a minor compression on the anterior part of the heart. It had close relation to the ribs, no surrounding fat, and a thymoma was suspected. Biopsy prior to surgery was impossible due to the location of the tumor. Unfortunately, final pathology from the surgical specimen revealed a chondrosarcoma.
