Malignant transformation of a tracheal chondroma: The second reported case and review of the literature

Abstract

Tracheal tumors are rare, representing only 0.2% of the respiratory tract malignancies. Chondrosarcoma arising in the trachea was first described in 1959 by Jackson et al. and since then only 20 cases have been described. We report the second documented case of malignant transformation from an endotracheal chondroma, in a 75-year-old woman, and review the literature. Keywords: Trachea, Chondroma, Chondrosarcoma
