A Case of Tracheal Chondrosarcoma

Background. Chondrosarcoma of the trachea is an extremely rare malignant tumor, accounting for only 0.1 % of all tracheal tumors. It is believed that chondrosarcoma arises from malignant degeneration in mesenchymal pluripotent cells of cartilage tissue, ossified cartilage, and enchondromas. Chondrosarcoma of the trachea is the least-studied tumor, with only 35 cases described in the literature from 1959 to 2020. Surgery with R0 resection remains the gold standard treatment of tracheal chondrosarcoma. The median age of patients at the time of diagnosis was 68 years, and 91 % were male. The most common symptoms at the initial visit were dyspnea (up to 80 % of cases). Tumors located in the proximal third of the trachea were observed in 54 % of cases, while tumors in the distal third of the trachea were found in 29 % of cases. Low-grade tumors (G1) were the most common (54 %). Computed tomography of the chest is considered the gold standard for the detection of tracheal tumors.
