title: Castleman's disease presenting as a tracheal mass.
abstract: Castleman's disease (CD) is a rare lymphoproliferative disorder of uncertain cause. The most common site of involvement is the mediastinum. Endotracheal CD is extremely rare. We report a case of unicentric, hyaline-vascular type CD presenting as an obstructive tracheal mass. The tumor was successfully managed by rigid bronchoscopy with argon plasma coagulation. There was no recurrence at the 2-month follow-up visit.
