[Metastatic melanoma to the oropharynx].

INTRODUCTION

Metastatic mucosal melanoma to the oropharyngeal area is extremely rare. Only 0.6% to 3% of patients with cutaneous malignant melanoma will have metastases to the mucosa of the upper aerodigestive tract.

CASE REPORT

A 60-year-old woman presented with a past history of dorsal melanoma and metastatic inguinal node was referred to our department for odynophagia. Physical examination revealed a mass of the right tonsil. A cervico-facial computed tomography, a magnetic resonance imagery and PET-scanner were performed and showed the tumefaction located at the right tonsil. Biopsy was performed under general anesthesia. The histological examination revealed a metastatic melanoma. After discussion a palliative treatment with chemotherapy was begun. The patient died of disseminated disease 2 months after the beginning of the chemotherapy, only 4 months after the initial diagnosis.

DISCUSSION/CONCLUSION: The case presentation indicates that careful examination of the head and neck should be part of the routine follow-up examination in all melanoma patients. The discovery of mucosal metastasis in head and neck indicated widespread dissemination and a poor prognosis.
