What condition is indicated by darkened or velvety skin on a patient's neck, groin, and axilla?

Seborrheic Keratosis
Actinic keratosis
Keratoacanthoma
Acanthosis nigricans

The correct answer is: Acanthosis nigricans

Acanthosis nigricans is characterized by darkened or velvety skin, typically found in areas such as the neck, groin, and axilla. This condition is often associated with insulin resistance and can be indicative of underlying metabolic disorders, such as obesity and type 2 diabetes. The thickened, discolored skin results from an increase in the number of skin cells in the epidermis and changes in pigmentation, which gives it a velvety texture. Patients with acanthosis nigricans may also present with other associated symptoms, depending on the underlying cause, and the condition can serve as an important clinical sign for healthcare providers in assessing potential metabolic abnormalities. Recognizing this condition is crucial, as it can lead to further investigation into possible related health issues, allowing for timely intervention and management.
