Abstract
Malignant peripheral nerve sheath tumors are part of 5% of soft tissue sarcomas. Although they are infrequent, their incidence increases in case of neurofibromatosis type 1. When these tumors are located in the head and neck, they are usually asymptomatic, so their diagnosis is delayed. Treatment is primarily surgical, with a significant recurrence rate and poor 5-year survival. We present a case report of a 52-year-old patient with a history of type 1 neurofibromatosis and a malignant peripheral nerve sheath tumor of the vagus, located in the parapharyngeal space.
