What are the 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. All of these conditions can be considered potentially dangerous. • Acanthosis nigricans can affect otherwise healthy people, or it can be associated with medical problems. Some cases are genetically inherited. • It is most common among people of African descent. Obesity can lead to acanthosis nigricans, as can many endocrine disorders. It is frequently found in people with diabetes. • Some drugs, particularly hormones such as human growth hormone or oral contraceptives (“the pill”), can also cause acanthosis nigricans. • People with cancers of the gastrointestinal or genitourinary tracts or with lymphoma can also develop severe cases of this acanthosis nigricans.
