The use of CP-EBUS-TBNA in the diagnosis of chondrosarcoma in a patient With Maffucci syndrome.We report a case of a 52-year-old white woman with Maffucci syndrome, a rare skeletal disorder characterized by multiple cartilage-forming tumors (enchondromas).  She underwent a convex-probe endobronchial ultrasound (CP-EBUS)-guided transbronchial needle aspiration (TBNA) that confirmed metastatic chondrosarcoma.  Although CP-EBUS-TBNA has become an established tool for diagnosing and staging of non-small cell lung cancer, analysis of samples from rare tumors such as sarcomas by cytology alone is often inadequate and histologic confirmation using more invasive procedures is often required.  Moreover, the location of the lesion was the superior segment of the left lower lobe, an area typically not accessible by CP-EBUS, due to the size of the airway.  Considering together, the successful diagnosis of a rare tumor such as sarcomas by CP-EBUS-TBNA modality indicates the growing importance of this minimally invasive technology.
