#asktheexpert My baby is having this mark from birth .. what is it?

A. White patches on a baby's skin can be caused by several factors. Here are a few common possibilities: 1. Congenital Nevus: These are benign pigmented lesions that can appear as white patches. They are typically harmless. 2. Pityriasis Alba: This is a common skin condition in children characterized by light-colored patches, often more noticeable on darker skin. It may be associated with dry skin. 3. Vitiligo: This is a skin condition that causes loss of pigment, resulting in white patches. It's rare in infants but can develop in early childhood. 4. Tinea Versicolor: A fungal infection that can cause lighter or darker patches on the skin. 5. Eczema or Allergic Reactions: Some skin conditions can lead to light patches due to inflammation or irritation. It's best to consult a pediatrician or dermatologist to get a proper diagnosis and treatment plan if needed. They can assess the patch and determine if it requires any attention.
