Special circumstances in the management of melanoma: Recurrence, metastasis, and nonsurgical approaches

<h2>Abstract</h2> While the primary treatment of cutaneous melanoma in the head and neck region is often straightforward, clinicians frequently encounter complex scenarios that require nuanced management strategies. This chapter addresses special circumstances in melanoma care, specifically focusing on disease recurrence, metastatic progression, and treatment alternatives for poor surgical candidates. It begins by outlining the patterns of recurrence and the appropriate surveillance and intervention strategies for local, regional, and distant relapse. The discussion then shifts to the management of metastatic disease, reviewing current paradigms in systemic therapy—including immunotherapy and targeted agents—and the role of metastasectomy. Finally, the chapter evaluates non-operative approaches for patients who are unable to undergo surgery due to comorbidities or anatomical constraints, exploring modalities such as radiation therapy and intralesional treatments. This overview provides a framework for decision-making in these challenging clinical presentations.
