👉 Keratodermia is a condition that occurs in infants and children, often due to an abnormal growth of the skin cells called keratinocytes. These cells are responsible for producing hair, nails, skin, and other organ structures. The condition can cause abnormal growths on the skin, such as small bumps or patches that look like small craters or lumps. Keratodermia is typically diagnosed in infancy and occurs due to a lack of adequate supply of keratinocytes
