Sinonasal teratocarcinosarcoma is a rare aggressive malignant tumor with a primary setting involving the nasal cavity followed by the ethmoid sinus and maxillary sinus. It accounts for approximately 3% of all head and neck cancers and less than 1% of all tumors. Nasal obstruction, recurrent epistaxis and headache represent the typical clinical presentation. Imaging shows the presence of a mass in the nasal cavity. The treatment usually consists of surgery and adjuvant intensity modulated radiotherapy. The rarity and the variability of the histological features make its diagnosis particularly difficult. In this paper, we report a case of sinonasal teratocarcinosarcoma in a 62-year-old male treated with a multidisciplinary approach. As an alternative to intensity modulated radiotherapy, we proposed proton beam therapy for the first time. The patient benefited from the new and personalized protocol that provided excellent results and few adverse effects. At 45 months follow-up there is no evidence of relapse and the patient is in good health.

Abstract

Sinonasal teratocarcinosarcoma is a rare aggressive malignant tumor with a primary setting involving the nasal cavity followed by the ethmoid sinus and maxillary sinus. It accounts for approximately 3% of all head and neck cancers and less than 1% of all tumors. Nasal obstruction, recurrent epistaxis and headache represent the typical clinical presentation. Imaging shows the presence of a mass in the nasal cavity. The treatment usually consists of surgery and adjuvant intensity modulated radiotherapy. The rarity and the variability of the histological features make its diagnosis particularly difficult. In this paper, we report a case of sinonasal teratocarcinosarcoma in a 62-year-old male treated with a multidisciplinary approach. As an alternative to intensity modulated radiotherapy, we proposed proton beam therapy for the first time. The patient benefited from the new and personalized protocol that provided excellent results and few adverse effects. At 45 months follow-up there is no evidence of relapse and the patient is in good health.
