RESUMEN
Context: Parapharyngeal space tumors comprise less than 0.5 per cent of all head and neck neoplasms. The majority of these tumors are benign, but surgery is usually required to establish the diagnosis and treat the patients. We present 26 patients treated surgically for tumors arising in the parapharyngeal space (PPS) at the State University of Campinas Hospital - UNICAMP. Cases Serie: Of these, 17 (65.5 per cent) had benign and 9 (34.6 per cent) malignant neoplasms. The surgical and pathological data relevant to these cases are highlighted, observing any local recurrence, surgical complications and the five-year survival. Neurogenic tumors and soft tissue sarcomas were, respectively, the most frequent benign (35.3 per cent) and malignant neoplasms (44.5 per cent). Benign tumors accounted for the majority of the cases and involved minimal surgical morbidity with no recurrence during a median follow-up of five years. Malignant tumors had a high rate recurrence and mortality. Surgery is the treatment of choice for PPS tumors. A knowledge of the anatomy of this site is essential for the safe performance of surgical procedures. Malignant neoplasms have a poor prognosis. Fine needle aspiration was helpful in diagnosis of all tumors.

The recurrence of melanoma in patients is well-documented, and is dependent on a number of factors. We report a case in which a patient had a case of galglionar metastasis in the neck after a 30-year disease-free interval following primary treatment.
