Acanthosis Nigricans (Pictures)

Acanthosis nigricans is a disorder that may begin at any age. It causes velvety, light-brown-to-black, markings usually on the neck, under the arms or in the groin. Acanthosis nigricans is most often associated with being overweight.

Causes of acanthosis nigricans

The exact cause of this acanthosis nigricans is unknown. It can be a genetic (inherited) condition. When inherited, it is not considered dangerous. However it is sometimes associated with obesity, diabetes, cancer and certain drugs.

Symptoms of acanthosis nigricans Acanthosis nigricans usually appears slowly and doesn't cause any symptoms other than skin changes. Eventually, dark, velvety skin with very visible markings and creases appears in the armpits, groin, and neck. Sometimes, the lips, palms, soles of feet, or other areas may be affected.

Treatment for Acanthosis nigricans

Because acanthosis nigricans itself usually only causes changes to the appearance of the skin, no particular treatment is needed. It is important, however, to attempt to treat any underlying medical problem that may be causing these skin changes. Some treatments of acanthosis nigricans include the following:

• When acanthosis nigricans develops a medical work-up should be done to determine whether or not the patient has a gland (endocrine) disorder or a tumor.
• Treatment to just improve the appearance includes Retin-A, 20% urea, alpha hydroxyacids, and salicylic acid prescriptions.

Acanthosis nigricans may not be life threatening but it sure indicates an underlying condition that may prove fatal if ignored. Therefore it is necessary for the examiner to make a proper diagnosis so that the patient can be treated accordingly and any new or worsening symptoms can be controlled before they assume a malignant form.
