Metachronous Cutaneous Melanoma Metastases of the Left Anterior Paranasal Sinuses and the Right Nasopharynx That Were Treated Surgically: A Case Report With Literature Review.

Metastases of cutaneous melanoma to the paranasal sinuses and nasopharynx are considered rare. We reported the case of a patient with cutaneous melanoma metastasizing to the left anterior infundibulum and seven months later to the right nasopharynx that was successfully treated by endonasal endoscopic surgery as a single treatment modality. No adjuvant radiotherapy was performed.
