چکیده

Insulin resistance is a metabolic disorder in which target cells fail to respond to normal levels of circulating insulin. Insulin resistance has been associated with presence of acanthosis nigricans and acrochordons. It is known that early diagnosis and early initial treatment are of paramount importance to prevent a series of future complications. These dermatoses may represent an easily identifiable sign of insulin resistance and non-insulin-dependent diabetes.

Clearance of acanthosis nigricans associated with insulinoma following surgical resection.

Acanthosis nigricans is said to be a marker of insulin resistance. It is known to occur in patients with insulinoma where there is marked hyperinsulinaemia.
