Acral Nevus

Acral nevus, also known as a melanocytic nevus or a mole, is a common skin growth that appears as a dark, pigmented spot on the skin’s surface. While most moles are harmless, it’s important to understand their different types, causes, symptoms, diagnostic tests, treatments, and medications. In this article, we will simplify the complex terminology and provide clear explanations to improve understanding and accessibility.

Types of Acral Nevus:

  1. Common Acral Nevus: These are the typical moles that most people have. They are usually small, brown, and round or oval in shape.
  2. Atypical Acral Nevus: These moles have irregular borders, and uneven coloring, and may be larger than common moles. They are more likely to change over time.

Causes of Acral Nevus:

  1. Genetics: Your genes play a significant role in the development of moles. If your family has a history of moles, you may be more prone to them.
  2. Sun Exposure: Prolonged sun exposure, especially during childhood, can increase the risk of developing moles on acral areas like hands and feet.
  3. Hormonal Changes: Hormonal fluctuations during puberty, pregnancy, or while taking birth control pills can trigger the formation of moles.
  4. Aging: Moles can develop as you age, often appearing in areas exposed to sunlight.
  5. Immune System Factors: Weakened immune systems, such as in people with autoimmune diseases, may be more susceptible to moles.
  6. Unknown Factors: In some cases, moles may appear without any clear cause.

Symptoms of Acral Nevus:

  1. Pigmented Spots: The primary symptom is the presence of dark, pigmented spots on the skin.
  2. Asymmetry: Moles that are not symmetrical in shape may indicate an atypical acral nevus.
  3. Irregular Borders: Moles with irregular or poorly defined borders should be examined.
  4. Color Variation: Moles with multiple colors or uneven coloring may be concerning.
  5. Changes Over Time: Any changes in size, shape, or color of a mole should be monitored.
  6. Itchiness or Bleeding: Moles that itch, bleed, or become painful require attention.

Diagnostic Tests for Acral Nevus:

  1. Visual Examination: A healthcare provider will visually inspect your moles to determine if they appear typical or atypical.
  2. Dermatoscopy: This involves using a dermatoscope, a specialized tool, to examine moles in more detail.
  3. Biopsy: If a mole looks suspicious, a small tissue sample may be taken for examination under a microscope to check for abnormal cells.
  4. Digital Imaging: Some clinics use digital imaging systems to track changes in moles over time.
  5. Total Body Photography: In cases of multiple moles, total body photography helps monitor changes in the skin.
  6. Mole Mapping: This involves creating a detailed map of your moles for tracking changes.

Treatment Options for Acral Nevus:

  1. Observation: If a mole appears normal, your healthcare provider may recommend regular monitoring for changes.
  2. Excisional Biopsy: Suspicious moles may be surgically removed for further examination.
  3. Shave Excision: Raised moles can be shaved off the skin’s surface for cosmetic or diagnostic reasons.
  4. Cryotherapy: Freezing the mole with liquid nitrogen is an option for certain types of moles.
  5. Laser Removal: Lasers can be used to break down pigmented cells in moles.
  6. Electrosurgery: An electrical current is used to remove the mole.
  7. Radiation Therapy: In rare cases, radiation may be used to treat large or atypical moles.
  8. Topical Medications: Some creams or ointments may be prescribed for specific types of moles.
  9. Chemical Peels: Superficial moles can be treated with chemical peels.
  10. Mohs Surgery: This precise surgical technique removes layers of tissue one at a time until no abnormal cells remain.
  11. Photodynamic Therapy: A combination of light and a special medication can treat certain types of moles.
  12. Curettage: The mole is scraped off the skin’s surface with a curette.
  13. Radiofrequency Ablation: Heat is used to remove the mole.
  14. Punch Biopsy: A cylindrical tool removes the mole for examination.
  15. Micrographic Surgery: A precise surgical technique used for removing complex or larger moles.
  16. Carbon Dioxide (CO2) Laser: This laser is used to vaporize the mole tissue.
  17. Radiotherapy: In some cases, radiation therapy may be recommended.
  18. Laser Resurfacing: Ablative lasers can remove moles and improve skin texture.
  19. Microdermabrasion: This procedure can be used to exfoliate the skin’s surface and improve the appearance of moles.
  20. Intralesional Corticosteroid Injection: Steroid injections may be used to reduce inflammation and improve the appearance of moles.

Medications for Acral Nevus:

  1. Topical Corticosteroids: These creams or ointments can help reduce inflammation and itching in moles.
  2. Imiquimod: This topical medication stimulates the immune system and may be used to treat certain types of moles.
  3. 5-Fluorouracil (5-FU): A topical cream that can be used to treat some types of moles.
  4. Retinoids: These medications can help improve the appearance of moles and the surrounding skin.
  5. Antibiotics: If a mole becomes infected, antibiotics may be prescribed.
  6. Pain Medications: Over-the-counter pain relievers can be used to manage discomfort after mole removal procedures.
  7. Antihistamines: These can help relieve itching associated with moles.
  8. Analgesics: Prescription pain medications may be necessary for more extensive mole removal procedures.
  9. Anti-inflammatory Medications: These may be prescribed to reduce inflammation.
  10. Anti-viral Medications: If a mole is associated with a viral infection, antiviral drugs may be necessary.

Conclusion:

Acral nevus, or moles, can vary in types and presentation. While most are harmless, it’s crucial to monitor them for any changes. Causes can range from genetics to sun exposure, and diagnosis involves visual examination and, if necessary, biopsy. Treatment options include various surgical techniques, laser therapy, and medications. If you have concerns about your moles, consult a healthcare provider for proper evaluation and guidance.
