Abstract
Mesenchymal chondrosarcoma is a rare highly differentiated malignant tumor with a characteristic histological structure, which affects bones or soft tissues and has a high potential for local recurrence. The small number of observations of mesenchymal chondrosarcoma in the head and neck region causes the episodic nature of studies of this problem, and the treatment and diagnostic tactic remains controversial. The article presents the results of the most extensive and systematic studies, which show that the main method of treatment for this category of patients is surgical. Neoadjuvant or adjuvant chemotherapy tends to improve overall survival. Radiation therapy is used as adjuvant treatment. The work provides a clinical case of a long lifetime of a patient with local recurrence of the disease in the absence of regional, distant metastasis and the use of all current methods of treatment for cancer.References
