Anemia resolved by thoracoscopic resection of a mediastinal mass: a case report of unicentric Castleman’s disease

Castleman’s disease (CD) is an uncommon benign lymphoproliferative disorder that usually presents as a single or multiple mediastinal mass. In unicentric CD, constitutional symptoms are rare, but are curable with surgical resection. However, serious intraoperative bleeding often requires conversion to thoracotomy. We present a case of unicentric CD in a 25-year-old woman with anemia, who was successfully treated by thoracoscopic resection. We describe the clinical course from the initial presentation to diagnosis and surgical cure.
