Hamartomas form in different parts of the body, especially the skin, mouth, and gastrointestinal tract. Other benign tumors may also occur in the thyroid, breast, uterus, soft tissue, and brain. Other signs and symptoms include a larger-than-average head, abnormal skin changes, blood vessel problems, autism spectrum disorder, and learning and developmental delays.
