My son was born with aplasia cutis congenita. He is now one year old and the spot on his head is about 4 inches long and 1/2 inch wide. As his head grows, the lesion continues to get bigger. His dermatologist has prescribed a skin cream to keep it moist, but my son continues to scratch it open daily. My son's doctor says that there is nothing that can be done until he is a teenager when a portion of the membrane can be removed and his scalp can be stitched together. I can't see waiting that long without a better recommendation. What treatment options are available?
