Acral lentiginous melanoma is characterized by its occurrence on the extremities, such as the palms, soles, and under the nails, as well as on mucous membranes. This type of melanoma is particularly notable for its presentation in areas that are often difficult to examine and may go unnoticed for longer periods, which can delay diagnosis. The fact that it commonly appears in these locations distinguishes it from other forms of melanoma, which are typically found on sun-exposed areas of the skin.

While other features may be present in melanoma, the locations of acral lentiginous melanoma are unique and significant both for clinicians and for patients. This type of melanoma can also occur in individuals with darker skin tones, making it an important condition to recognize because it may be overlooked due to less common awareness compared to other melanoma types. Understanding these location characteristics is crucial for improving early detection and treatment outcomes in patients at risk for this form of melanoma.
