Abstract

Primary malignant melanoma in the oropharynx is extremely rare. A 49-year-old man presented with a 3-month history of progressive dysphagia. An outside CT scan of the head and neck showed a space-occupying lesion in the oropharynx. Staging with FDG PET/CT demonstrated a hypermetabolic mass in the right wall of the oropharynx. A biopsy revealed malignant melanoma. The patient underwent total resection of the tumor, with no recurrence after 6-month follow-up.
