Strawberry hemangiomas are benign growths made up of blood vessels that typically appear as bright red or purple marks on the skin. They are most commonly found in infants and usually develop within the first few weeks of life. These growths can vary in size and may grow rapidly before gradually shrinking over time. While strawberry hemangiomas are generally harmless and do not require treatment, they can sometimes cause complications if they interfere with vision, breathing, or other functions. In most cases, they fade away completely by the time a child reaches school age, leaving little to no trace behind.
