Diagnostic Questions for Acanthosis Nigricans

Your doctor may ask these questions to check for this disease:

  • Do you have darkened skin?
  • Do you have any rough patches in your mouth or genital area?
  • Is your skin itchy?
  • Are you feeling nauseous or have you been vomiting?
  • Is your skin getting harder from fingertip to back of your hand?

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
