Acral lentiginous melanoma is a type of skin cancer that starts in the palms, soles, or toes. It slowly spreads over time and often creates large patches on the skin that can resemble moles. This article discusses the basics of what acral lentiginous melanoma is and how to treat it.
What is Acral Lentiginous Melanoma?
Acral lentiginous melanoma is a type of skin cancer that usually affects the palms, soles, and other areas on the hands and feet.
It is considered a less common type of skin cancer than other types, such as basal or squamous cell carcinoma.
The cause of acrals lentiginous melanoma is not known, but it may be related to exposure to the sun or ultraviolet radiation.
The most common treatment for acrals lentiginous melanoma is surgery, though radiation therapy may also be used.
Types of Acral Lentiginous Melanomas
There are three main types of acral lentiginous melanoma: classic, junctional, and truncal. Classic melanomas are the most common type and account for approximately 70 percent of all cases. They are generally less than one inch wide and have a central lesion that is either red or brown in color. Junctional melanomas have a more diffuse distribution and can occur anywhere on the skin. Truncal melanomas are the rarest type and are found only in people over the age of 50. They are the widest form of melanoma and often grow rapidly.
The best way to prevent acrals lentiginous melanoma is to keep skin cancer free by using a sunscreen every day, avoiding exposure to sunlight, and getting regular checkups. If you notice any changes in your skin, such as a new mole, you should see your doctor immediately.
How to Treat a New Acral Lentiginous Melanoma
Acral lentiginous melanoma (ALK) is an uncommon skin cancer that primarily affects the face, neck, and hands. It is also known as lentigo maligna acralis or “acrals lentiginous melanoma.” Acrals lentiginous melanoma typically arises on sun-exposed areas of the body, such as the face, neck, and hands. The cancer is a type of melanoma that arises from the pigment cells in the skin. Unlike other types of melanomas, which can grow rapidly and spread to other parts of the body, acrals lentiginous melanoma is slow growing and rarely spreads.
ALK is treated primarily with surgery to remove the tumor. However, if the tumor is limited to a small area or does not metastasize (spread), surgery may not be necessary. In some cases, radiation therapy or chemotherapy may also be used to treat cancer. If cancer has spread beyond the original site, treatment may include radiation therapy or chemotherapy as well as traditional surgical treatments. Acral lentiginous melanoma is highly treatable with successful outcomes in most cases.
