What is Acral Lentiginous Melanoma?
Acral lentiginous melanoma (ALM) is a special kind of skin problem. It shows up on parts of the body that don’t get much sun, like palms, soles, and under nails. It’s often mistaken for less serious skin issues, so catching it early is key.
Definition and Characteristics
ALM has its own signs, like uneven color and strange shapes. It grows on the skin of hands, feet, and nails. Because its signs can be hard to spot, it’s vital to check your skin often.
Prevalence and Demographics
ALM is not very common but hits people of African, Asian, and Hispanic backgrounds more often. It’s more aggressive and usually found later, making it important to know about it and check your skin early. Acral Lentiginous Melanoma Risks
| Ethnic Group | Prevalence Rate |
|---|---|
| African Descent | 4% |
| Asian Descent | 3% |
| Hispanic Descent | 2% |
| Caucasian Descent | 0.8% |
Signs and Symptoms of Acral Lentiginous Melanoma
Acral Lentiginous Melanoma (ALM) shows up differently than other skin cancers. Knowing the early signs is key. Spotting these signs early can lead to better health.

A common sign of ALM is new or odd color spots on palms, soles, or under nails. These spots can grow bigger over time. ALM doesn’t always follow the usual “ABCDE” rule, making it harder to spot.
Changes in the Appearance of Moles
Watching moles for changes is important. Look for color, shape, or size changes. Itching, tenderness, or bleeding can mean trouble. Checking moles, especially on feet, helps keep skin healthy and catches melanoma early.
How Acral Lentiginous Melanoma Differs from Other Types of Skin Cancer
Acral Lentiginous Melanoma (ALM) is different from other skin cancers. It has unique features that help doctors diagnose and treat it right.
Location: ALM doesn’t show up in the sun like other cancers. It’s found on places like palms, soles, and under nails. This makes it special for doctors to spot.
Growth Patterns: ALM looks like a dark, uneven patch that gets bigger. It grows differently than basal and squamous cell carcinomas. Doctors need to know these differences to treat it well.
Pathology: ALM starts in deeper layers of the skin. This makes it more serious and likely to spread. Finding it early is very important.
Here’s a comparison of ALM with other skin cancers:
| Features | Acral Lentiginous Melanoma (ALM) | Basal Cell Carcinoma | Squamous Cell Carcinoma |
|---|---|---|---|
| Typical Location | Palms, soles, under nails | Sun-exposed areas, e.g., face, neck | Sun-exposed areas, e.g., face, hands |
| Growth Pattern | Dark, uneven patches, progressive enlargement | Slow-growing, localized lesions | Rough, scaly patches, faster growth |
| Pathology | Deep epidermal origin, highly invasive | Superficial epidermal origin, less invasive | Epidermal surface origin, moderate invasiveness |
Doctors can make better diagnoses and treatments by knowing these differences. Understanding ALM’s unique features is key in the medical field.
Common Risk Factors
Acral Lentiginous Melanoma Risks It’s important to know the risk factors for melanoma. This helps us find out who might get acral lentiginous melanoma (ALM). These risks fall into three main groups: genetics, environment, and age.
Genetic Predisposition
Genetics and melanoma are closely linked. Some genes, like CDKN2A and BAP1, make you more likely to get melanoma. Families with a history of melanoma often have these genes. This shows why genetic testing is key for those at risk.
Environmental Influences
Even though ALM is less common than other skin cancers, the environment still matters. UV rays from the sun or tanning beds can harm your skin. Smoking and chemicals can also raise your risk. Acral Lentiginous Melanoma Risks
Age and Demographic Considerations
ALM gets more common with age. It’s often found in people over 60. Some groups, like African Americans, Asians, and Hispanics, are more likely to get ALM. This means we need to teach these groups more about it.
Preventive Measures for Reducing Risk
To lower the risk of acral lentiginous melanoma (ALM), use many prevention steps. These steps include regular skin checks and using UV protection. They help keep your skin safe.
Regular Skin Examinations
Doing skin exams often is key to finding ALM early. See a dermatologist regularly and check your skin yourself. Look for moles that are not even or have strange edges.
Protective Clothing and Sunscreen
Wearing protective clothes is very important for UV protection. Long sleeves, wide hats, and sunglasses block harmful rays. Also, use sunscreen with SPF 30 or higher on all skin that’s exposed.
- UV Protection: Put on sunscreen often, especially after swimming or sweating.
- Protective Clothing: Pick UPF-rated clothes for the best UV block.
- Shade and Timing: Stay in the shade when the sun is strongest and plan your day outside wisely.
By following these prevention steps and doing skin exams, you can lower your risk. This helps keep your skin healthy for a long time.
How to Perform Self-Exams
Early detection of melanoma is key. Regular self-exams help spot changes early. This guide will show you how to do self-checks effectively.
Step-by-Step Guide
- Find a well-lit room: Make sure the room is bright for clear skin checks.
- Use mirrors: Use a full-length mirror and a handheld mirror to see all areas.
- Check your hands and feet: Look closely at palms, soles, and under nails, where ALM often shows up.
- Examine your entire body: Check all skin areas, including between fingers and toes, and under arms and breasts.
- Look for changes: Watch for new spots, growths, or changes in moles, especially those that look irregular.
- Keep a record: Write down any changes and take photos for future comparisons.
- Seek professional advice: If you find something odd, see a dermatologist right away.
Tools and Resources
Using the right tools and resources makes self-exams better for ALM.
- Dermoscopy devices: Dermatoscopes help see skin lesions up close for better checks.
- Educational guides and apps: Guides and apps, like those from Acibadem Healthcare Group, offer step-by-step help and reminders.

Acral Lentiginous Melanoma Diagnosis
Acral Lentiginous Melanoma Risks Diagnosing ALM is very important. It starts with a visual examination by a dermatologist. They look for signs of melanoma in the skin.
If a spot looks odd, a melanoma biopsy is done. This means taking a piece of tissue for tests. The goal is to find cancer cells.
More tests might be needed. This could include pictures of the inside, blood tests, and more biopsies. Acral Lentiginous Melanoma Risks
Getting help from a skin expert is key. Dermatologists know how to spot ALM. They help plan the best treatment.
| Diagnostic Step | Details |
|---|---|
| Visual Examination | Initial inspection with dermoscopy for suspicious moles or lesions. |
| Melanoma Biopsy | Removal and pathological assessment of tissue sample for cancer cells. |
| Pathological Assessment | Microscopic examination to confirm presence and type of melanoma. |
| Skin Cancer Screening | Additional tests including imaging and blood tests. |
| Expert Consultation | In-depth evaluation by dermatology specialists for accurate diagnosis. |
Treatment Options for Acral Lentiginous Melanoma
Acral Lentiginous Melanoma (ALM) needs a special treatment plan. This includes surgery, radiation, and new treatments from trials. Knowing these options helps patients make good choices.
Surgical Procedures
Surgery is key in treating ALM. Doctors aim to remove the tumor and some healthy tissue too. This helps ensure all cancer is gone.
The type of surgery needed depends on the melanoma’s size and where it is. Early detection helps surgery work better.
Radiation and Chemotherapy
Acral Lentiginous Melanoma Risks When surgery isn’t possible, radiation and chemotherapy are used. Radiation uses high-energy rays to kill cancer cells. Chemotherapy uses strong drugs to do the same.
These treatments are part of a complete plan to fight melanoma. They are tailored to each patient’s needs.
Emerging Treatments and Clinical Trials
New treatments for melanoma are being tested in trials. Immunotherapy and targeted therapy are leading the way. They help the body fight cancer and target specific tumor genes.
Joining a trial can give patients access to new treatments. These might offer better results than old methods. It’s important for patients to keep up with new research.
