Spectroscopic and Colorimetric Analysis of Acanthosis Nigricans in Patients With Hyperinsulinemia

• Status: Completed
• Trial end date: 2012-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Acanthosis Nigricans is skin disease that associated with hyperinsulinemia. Clinical is velvety hyperpigmented plaques on neck, axilla, groin. If hyperinsulinemia is improved by treated with oral metformin and/ or diet control, acanthosis nigricans would be improved as well. Hyperpigmented plaques will be changed. We assess objective measurement by using spectroscopic and colorimetric analysis.
