[Decompensated sinusitis complicated by cancer of the nasal cavity and the maxillary sinus].

This paper was designed to illustrate the probability of the development of an oncological disease of the nasal cavity and the paranasal sinuses in young subjects presenting with long-standing decompensated chronic sinusitis; also, it demonstrates the possibility of long-term remission after surgical elimination of the inflammatory process. A 28 year-old patient is described having decompensated chronic pansinusitis complicated by sepsis and secondary suppurative dacryocystitis. Multiple surgical interventions on several paranasal sinuses for the treatment of this pathology proved inefficient and were followed by sanation rhinosinusotomy with the simultaneous removal of the malignant tumour. The long-term monitoring of paranasal sinus condition after radical pansinusotomy and ablation of the tumour followed by a course of radiotherapy gave evidence of the malignant process with simultaneous elimination of inflammatory changes in paranasal sinuses.
