Objective: The purpose of this article is to report our experience with neurotropic melanoma, a rare malignancy that sometimes produces neurologic symptoms because of a direct extension of the primary tumor.
Methods: We report 3 consecutive patients with neurotropic melanoma of the head and neck who presented with clinical perineural invasion.
Results: Two patients had incompletely resectable tumors and were treated with definitive radiotherapy (RT), and 1 patient received surgery and postoperative RT. One patient experienced recurrence in a regional lymph node 30 months after RT and underwent salvage surgery; he is disease-free at 45 months after initial treatment. The remaining 2 patients are disease-free 34 months and 14 months after treatment.
Conclusions: Radiotherapy alone or combined with surgery may provide relatively long-term local control in patients who have neurotropic melanoma with clinical perineural invasion.

Perineural invasion (PNI) is a significant risk factor for cancer recurrence and metastasis; however, its mechanisms relating to cancer aggressiveness remain poorly understood. Here, we present a protocol for a non-surgical model of PNI in mice using a neurotropic melanoma cell line that migrates from the skin to the sciatic nerve. We describe the steps for cell culture and injection, tumor burden measurements, mouse euthanasia, and tissue dissection.

Primary orbital melanoma and metastatic cutaneous melanoma of the orbit are extremely rare. Desmoplastic melanoma (DM) is an infrequent variant of melanoma that can extend from a superficial location into deep tissues by neurotropic mechanisms. A 78-year-old male was referred to us with a periocular mixed malignant melanoma (spindle cell melanoma with desmoplastic reaction) in his left lower eyelid with uncontrollable disease (orbital and inferior orbital rim invasion) despite treatment.

Background: Cutaneous neurotropic melanoma (NM) of the head and neck (H&N) is prone to local relapse, possibly due to difficulties widely excising the tumor. This trial assessed radiation therapy (RT) to the primary site after local excision.
Methods: Participants from 15 international centers were randomized to observation or RT.
