Acanthosis nigricans (AN) is a condition characterized by a hyperpigmentation described as a brown-grey velvety thickening of the skin. AN commonly appears on the neck, axillae, and groin. AN can affect men, women, and children of all ages, and is predominant among African-Americans, Hispanics, and Native Americans.
AN can frequently be associated with other disorders such as metabolic or endocrine syndromes (obesity, diabetes, polycystic ovarian syndrome, insulin resistance, Cushing’s syndrome, acromegaly), or cancer. Due to this close relationship, AN’s early diagnosis is very important and can be the initial sign of another disease. AN can also appear in conjunction with a genetic or hereditary condition, like Down Syndrome; or as an adverse drug reaction to common medications like systemic glucocorticoids, insulin, or oral contraceptives, among others.
At Florida Skin Center, AN can be diagnosed clinically by one of our providers. AN is a benign skin condition, and in our offices we will address all related skin concerns with a variety of treatments. It is encouraging to know that, in many cases, AN can regress once the underlying cause is resolved.
If you have any questions about Acanthosis nigricans or any other skin condition, please contact any of our four offices and we will be happy to schedule an evaluation with one of our providers.
