Intrathoracic rosai-dorfman disease: hemorrhage with routine diagnostic procedure

Abstract

We present a case of a 33-year-old female with a slow growing, right peribronchial vascular mass and associated symptoms of progressive cough, dyspnea on exertion, and hemoptysis. On routine diagnostic flexible bronchoscopy with needle biopsy, the lesion hemorrhaged extensively requiring emergent thoracotomy, right lower and middle bilobectomy. The histopathology of the specimen was consistent with the rare and unusually located entity Rosai-Dorfman disease.
