Acanthosis nigricans, characterized by velvety skin patches and thickening, can be a concerning condition with various underlying causes. In this blog, we'll explore how to manage acanthosis nigricans, covering general measures, specific treatments, and addressing frequently asked questions.


Understanding Acanthosis Nigricans:

Acanthosis nigricans is often associated with underlying conditions like obesity, diabetes, and metabolic disorders. However, it can also be drug-induced, hereditary, autoimmune, or linked to internal malignancies in rare cases.

   a. **Lifestyle Modifications:**

      - Establishing a healthy diet.

      - Increasing exercise to combat insulin resistance.


   b. **Medications:**

      - Metformin and rosiglitazone to reduce insulin levels and improve lesions.


   c. **Malignant Acanthosis Nigricans:**

      - Careful workup and management of the underlying malignancy.

      - Cyproheptadine for regression associated with malignancy.


   d. **Drug-Induced Acanthosis Nigricans:**

      - Withdrawal of the suspected drug.


   e. **Syndromic Acanthosis Nigricans:**

      - Treatment of the underlying syndrome (e.g., oral contraceptives for polycystic ovary syndrome).


2. Specific Measures:

   a. **Pharmacological Treatment:**

      - Keratolytic agents (salicylic acid, glycolic acid, trichloroacetic acid).

      - Topical retinoids (adapalene gel, tretinoin cream).

      - Calcipotriol, Omega 3 fatty acids (fish oil), Podophyllin.


   b. **Procedural Modalities:**

      - Long-pulsed alexandrite laser therapy.


3. Outcome:

   - Hereditary acanthosis may stabilize or regress spontaneously.

   - Malignant acanthosis has a poorer prognosis, often associated with advanced cancer.
