An unusual pigmented tonsil neoplasm presenting to Head & Neck Clinic: a case report and literature review of primary tonsillar malignant mucosal melanoma.

Primary mucosal melanoma of the tonsil is rare, with 27 reported cases. Careful diagnosis is necessary, as the tonsil is more often a site of metastatic melanoma from a cutaneous primary tumour. In this report, we present a case of primary right tonsillar mucosal melanoma with widespread metastasis in a 31-year-old man who presented with a 3-month history of enlarging neck lumps.
