Acanthosis nigricans (AN) is a common dermatologic manifestation of systemic disease that is associated with insulin resistance, diabetes mellitus, obesity, internal malignancy, endocrine disorders, and drug reactions. Treatment of AN primarily focuses on resolution of the underlying disease processes causing the velvety, hyperpigmented, hyperkeratotic plaques found on the skin. Initial considerations for the AN workup include evaluating patients for insulin resistance syndrome characterized by obesity, dyslipidemia, hypertension, and diabetes mellitus type II. For cosmetic treatment, topical retinoids are considered the first-line therapy for insulin-resistant AN by modifying keratinization rate. However, topical tretinoin requires application for long durations and improves hyperkeratosis, but not hyperpigmentation. Topical salicylic acid, podophyllin, urea, and calcipotriol also require frequent application, while TCA peels may provide a faster and less time-intense burden.
