Acral Lentiginous Melanoma (ALM)

13 min read

Acral Lentiginous Melanoma (ALM) is a rare form of skin cancer that affects the palms of the hands, soles of the feet, and under the nails. It is the most common type of melanoma in people with darker skin tones, and is more likely to occur in people over the age of 50. ALM is caused by the abnormal growth of pigment-producing cells, known as melanocytes, in the skin.

Risk Factors

The exact cause of ALM is unknown, but certain factors may increase the risk of developing the condition. These include:

  • Exposure to ultraviolet (UV) radiation from the sun or tanning beds
  • A family history of melanoma
  • A weakened immune system
  • Certain genetic conditions, such as xeroderma pigmentosum

Diagnosis

ALM is usually diagnosed through a physical examination and biopsy. During the physical exam, the doctor will look for any suspicious moles or lesions on the skin. If a suspicious lesion is found, a biopsy will be performed to confirm the diagnosis. The biopsy will involve removing a small sample of the affected skin and examining it under a microscope.

Prevention

The best way to prevent ALM is to protect the skin from UV radiation. This can be done by avoiding direct sun exposure, wearing protective clothing, and using sunscreen with an SPF of 30 or higher. It is also important to check the skin regularly for any changes in moles or lesions.

  • Immune system disorders: People with weakened immune systems are at an increased risk of developing ALM.

It is important to note that having one or more of these risk factors does not necessarily mean that a person will develop ALM. However, it is important to be aware of these risk factors and to take steps to reduce your risk of developing this type of cancer.

Getting a Diagnosis

Diagnostic Tests

The diagnosis of ALM begins with a physical examination of the affected area. The doctor will look for any changes in the skin, such as a new mole or a change in an existing mole. If the doctor suspects ALM, they may order a biopsy of the affected area. During a biopsy, a small sample of the skin is taken and examined under a microscope. This can help the doctor determine if the skin cells are cancerous.

In addition to a biopsy, the doctor may order imaging tests such as an X-ray, CT scan, or MRI. These tests can help the doctor determine if the cancer has spread to other parts of the body. Blood tests may also be ordered to check for any signs of cancer in the blood.

Staging

Once ALM is diagnosed, the doctor will stage the cancer. Staging is a way of determining how far the cancer has spread. The stages range from 0 to IV, with stage IV being the most advanced. The stage of the cancer will help the doctor determine the best treatment plan.

Conclusion

Diagnosing ALM is important for determining the best treatment plan. The diagnosis begins with a physical examination and may include a biopsy, imaging tests, and blood tests. Once the cancer is diagnosed, the doctor will stage the cancer to determine how far it has spread. With early diagnosis and treatment, ALM can be managed effectively.
