Primary chondrosarcoma presenting as an intrathoracic mass: A report of three cases

Primary intrathoracic chondrosarcomas are rare tumors. The present study reports three cases of primary intrathoracic chondrosarcomas in two males and one female aged between 45 and 64 years. Clinically, one case presented with cough and blood sputum, while the other two cases of primary intrathoracic chondrosarcoma were found incidently during a routine health examination. Radiologically, the chondrosarcomas presented as large masses with intratumoral calcification. Chondrosarcoma should be distinguished from other calcified pulmonary lesions. In this study, all three cases underwent surgical treatment, and in one case, the surgery was accompanied by radiotherapy. To date, all patients have been followed up for between two and three years and are alive.
