The perforating ulcer is a dermatological lesion
, most frequently on the foot, whose origin is a neurological disorder. The best known perforating ulcer is the plantar ulcer that is predominantly seen in diabetic patients, mainly on the sole of the heel. The progression of diabetes
leads to a peripheral neuropathy
, among other complications
, with a loss of pain
sensation. The lack of feeling pain associated with the pressure generated by walking on the support areas initially causes mild inflammation
that evolves into a blister, then the area may grow larger in the absence of care and generate a wound which can go to the bone if these areas are not monitored. There is a major risk of infection. A rarer form is the perforating mouth
ulcer which causes a loss of teeth.
