Oral Melanoma in Older Adults: Epidemiology, Molecular Landscape, and Treatment Strategies.

Oral melanoma is an aggressive neoplasm arising from melanocytes in the mucosal epithelium, accounting for 0.2%-0.8% of all melanomas. Unlike cutaneous melanoma, it is not associated with UV exposure, and its pathogenesis involves complex genetic and molecular alterations. This neoplasm predominantly affects older adults (>/= 60 years). Clinically, lesions often present as macular or nodular with an exophytic growth pattern, sometimes ulcerated, and exhibit varied pigmentation. Diagnosis is further complicated by non-pigmented (amelanotic) variants that can resemble other oral pigmentations. Wide surgical excision remains the mainstay treatment, often combined with chemotherapy; however, recurrence and distant metastasis remain high. While immunotherapy has shown promise in other melanoma subtypes, its efficacy in oral melanoma remains uncertain. Treatment in older adults is particularly challenging due to comorbidities and treatment-related morbidity. This review summarizes the epidemiology, clinical features, and current treatment strategies for oral melanoma in older adults. Key advances in the molecular mechanisms underlying this neoplasm are also outlined. As a strategic approach, integrating oral melanoma screening into routine geriatric dental care, supported by diagnostic algorithms, may improve early detection, prognosis, and survival outcomes in this vulnerable population.
