How are you? Aplasia cutis congenita is a rare condition in which there is a congenital absence of skin and commonly affects the scalp, trunk, arms, and legs. The cause of this condition is unclear and appears to be multifactorial. It is the result of more than one disease process and more than one mechanism is involved. Aside from genetic factors, teratogens (eg, methimazole, carbimazole, misoprostol, valproic acid), compromised vasculature to the skin, and trauma are also responsible. In your case, this depends on the extent of the accidents, trauma and exposure to medications during this time. Talk to your doctor about this for proper management. Take care and best regards.
