Dr. Cobin describes the skin condition acanthosis nigricans.
Acanthosis is an unusual skin condition where the skin becomes a little thickened and furrowed and oftentimes it’s a little bit discolored, anywhere from mildly tannish to actually dark, dark brown or almost black. And typically it occurs in the sides or back of the neck, but it can occur other places as well as the elbows, around the waist, around the belly button, and sometimes underneath the breasts, and that condition is actually a marker on the skin for abnormalities in insulin secretion that allow us to know that these women are actually making too much insulin because their body isn’t responding properly to the insulin that they make.
