It can occur on various parts of the body, but most commonly affects the neck, under breast area armpits, and groin. The patches of skin affected by acanthosis nigricans may be tan, brown, or black in color, and may feel slightly raised and rough to the touch. The condition can develop gradually over time, and may be accompanied by itching or a bad odor. Acanthosis nigricans is often associated with insulin resistance and high blood sugar levels, and can be a sign of pre-diabetes or type 2 diabetes. It can also be caused by other underlying medical conditions, such as hormonal imbalances, obesity, or certain medications. Treatment for acanthosis nigricans typically involves addressing the underlying medical condition, such as improving blood sugar control or losing weight. Topical creams or ointments may also be prescribed to help improve the appearance of the affected skin. It’s important to see a healthcare professional if you notice any changes in your skin, including the development of acanthosis nigricans, as it can be a sign of an underlying medical condition that requires treatment. 👉 Shoes 👈 Best Shoes:

More questions patients ask

What is acanthosis nigricans and what causes it?

Acanthosis nigricans (AN) is a skin condition characterized by dark, thick, velvety skin in body folds and creases — most commonly the neck, armpits, and groin, but also the knuckles, elbows, and feet. The darkening and thickening result from epidermal hyperproliferation driven by insulin and insulin-like growth factors. The most common cause is insulin resistance (pre-diabetes, type 2 diabetes, polycystic ovary syndrome, obesity). Less commonly, it can be triggered by medications (niacin, corticosteroids, oral contraceptives) or rarely signal an underlying malignancy (acanthosis nigricans paraneoplastica). Finding acanthosis nigricans is an important visual marker of insulin resistance that warrants diabetes screening. Balance Foot & Ankle (810) 206-1402 — Howell and Bloomfield Township.

Is acanthosis nigricans a sign of diabetes?

Yes — acanthosis nigricans is strongly associated with insulin resistance and diabetes. In the pre-diabetic state, elevated insulin levels act on keratinocyte and fibroblast insulin-like growth factor receptors, stimulating epidermal overgrowth and melanocyte activity. The American Diabetes Association includes acanthosis nigricans as a physical sign supporting diabetes risk assessment. Severe acanthosis nigricans correlates with the degree of insulin resistance. Multiple studies show that acanthosis nigricans in overweight children and adolescents predicts future type 2 diabetes development. The presence of AN in any patient, regardless of age or body weight, should prompt fasting glucose, HbA1c, and insulin level testing.

Can acanthosis nigricans be treated or reversed?

Treatment depends on addressing the underlying cause. With insulin resistance: weight loss (even 5–10% body weight loss) significantly improves AN — the skin darkening visibly lightens with insulin sensitivity improvement. Blood sugar optimization with metformin also causes improvement. Topical treatments can improve appearance: retinoid creams (tretinoin), topical vitamin D analogs (calcipotriene), keratolytics (urea, salicylic acid, lactic acid), and triple combination lightening creams. For medication-induced AN, stopping or switching the offending medication resolves the condition. For malignancy-associated AN, treating the cancer causes AN to resolve. Completely reversing AN requires addressing the root cause, but topical treatments can meaningfully improve appearance.

Can acanthosis nigricans appear on the feet?

While acanthosis nigricans most commonly appears in the neck and axillary (armpit) creases, it can involve the feet — particularly the knuckles over the toes, the ankle creases, and less commonly the plantar surface. On the feet, dark, thickened skin in pressure areas may be confused with hyperkeratosis (calluses) or post-inflammatory hyperpigmentation. Key distinguishing features of AN: velvety texture, associated with skin fold areas, typically not preceded by inflammation, and found in multiple locations simultaneously. Diabetic patients with AN on their feet have significant underlying insulin resistance and likely other diabetic skin manifestations. Balance Foot & Ankle evaluates all unusual skin changes on diabetic feet at 4330 E Grand River, Howell and 43494 Woodward Ave #208, Bloomfield Township.

What is the connection between obesity, insulin resistance, and skin changes?

Obesity, particularly central (abdominal) obesity, drives insulin resistance through multiple mechanisms including adipokine dysregulation, chronic low-grade inflammation, and ectopic fat deposition. Elevated insulin levels from compensatory hyperinsulinemia stimulate IGF-1 receptors in the skin, causing the characteristic changes of acanthosis nigricans. This pathway also promotes skin tag formation (multiple skin tags are another cutaneous marker of insulin resistance). From a foot health perspective, obesity increases mechanical load on the feet, raises diabetes risk (and all its complications), promotes inflammation, and creates the metabolic environment that drives both cosmetic skin changes and serious complications. Balance Foot & Ankle addresses both the mechanical and metabolic contributors to foot health — call (810) 206-1402.

How often should diabetics check their feet?

Daily self-exams plus professional exams annually (or every 3-6 months for neuropathy/PAD patients). Dr. Biernacki provides comprehensive diabetic foot care programs.

Why do diabetics have foot problems?

Diabetes causes nerve damage, reduced blood flow, and impaired immunity. Injuries go unnoticed and heal slowly. ~15% of diabetics develop ulcers. Prevention through regular podiatric care is essential.

What are signs of diabetic neuropathy?

Tingling, burning, numbness starting in toes, sensitivity to touch, muscle weakness, balance problems. Schedule evaluation at 810-206-1402 for nerve testing and management.
