Therapeutic Strategies in Neurocutaneous Melanocytosis.

Neurocutaneous melanocytosis (NCM) is a rare, congenital condition primarily affecting children, characterized by large or giant congenital melanocytic nevi (L/GCMN) on the skin and pigmented lesions in the brain. The presence of pigmented lesions in the brain often leads to neurological symptoms like headaches, seizures, and hydrocephalus, typically manifesting before age two. Melanocytic lesions in the brain can range from benign melanocytosis to malignant melanoma. NCM is nearly always fatal if symptomatic, with a high risk of malignant transformation. Patients with larger skin nevi with neurological involvement tend to have a greater lifetime risk of malignancy. There is no specific treatment, and current therapies focus on palliative care, including surgery, radiation, and chemotherapy. Malignant transformation into melanoma requires aggressive treatments like surgery, radiation, and chemotherapy. Despite these approaches, outcomes remain poor, with no definitive cure for NCM. This study aims to review and critically evaluate the current therapeutic strategies for NCM while also exploring prospective avenues for developing specific and effective treatments. It aims to highlight recent advancements in the molecular understanding of NCM and examine how these insights may inform the development of novel therapeutic approaches. Additionally, the study will address the significant unmet medical needs associated with this rare and often fatal condition, emphasizing the importance of continued research and innovation in its management.
