Abstract:
A 64-year-old man presented with a pigmented cutaneous lesion on the right side of his face along with right facial numbness. Histological examination revealed malignant melanoma. Magnetic resonance imaging (MRI) revealed perineural extension along the entire course of the maxillary division of the right trigeminal nerve. This is a rare but important manifestation of the spread of head and neck malignancy.
