Acanthosis Nigricans – Symptoms and Causes

Overview

Acanthosis nigricans is a skin condition characterized by dark, thick, and velvety skin in body folds and creases. While it can occur in healthy individuals, it is most commonly linked to obesity and diabetes.

The primary symptom is dark, thickened patches that typically appear on the neck, armpits, groin, and other areas.

This condition often signals an underlying health issue, such as insulin resistance, diabetes, hormonal disorders, or, in rare cases, cancer. Certain medications can also trigger its development.

Diagnosis involves a physical examination and a review of medical history, with possible blood tests to identify underlying causes.

Treatment focuses on managing the root cause. Weight loss may improve symptoms if obesity is a factor. Topical treatments, such as retinoids or alpha hydroxy acids, may help lighten and soften affected skin.

In conclusion, recognizing acanthosis nigricans early can aid in addressing potential health concerns and improving skin appearance.
