Acanthosis Nigricans: Diagnostic Tests and Procedures
As acanthosis nigricans has hardly a single symptom, there are no elaborate diagnostic procedures and tests to detect presence of Acanthosis Nigricans. Doctors normally look at your skin and diagnose acanthosis nigricans. Sometimes, skin biopsy is done to detect possible changes in skin texture. A patch of skin is taken for biopsy at laboratory. Biopsy examines skin microscopically and evaluates any possible changes or lesions.
If there are no clear signs of acanthosis nigricans, doctors prescribe numerous tests like x-rays and blood tests to determine underlying medical conditions. Blood tests check blood sugar levels while X-rays and endoscopy detect presence of diabetes or cancer.
Neck discoloration as occurring in acanthosis nigricans is very similar to symptoms of Casal collar, a disease occurring due to nutritional deficiency. Early stages of discoloration are similar in both cases and even doctors are unable to detect accurately. However, nutritional supplements absolve Casal collar symptoms and thereafter it is simpler to diagnose acanthosis nigricans.
In adult patients with acanthosis nigricans symptoms, check malignancy of skin lesions as this is a common occurrence. Also, screen for insulin resistance. Normally, plasma insulin levels are high if you have insulin resistance. This test delivers perfect results even in young people with acanthosis nigricans. They normally do not have abnormal glycosylated hemoglobin level or overt diabetes mellitus. Yet, plasma insulin level is high indicating insulin resistance. This may cause acanthosis nigricans.
