A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life. A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. They tend to grow for up to a year before gradually shrinking as the child gets older. A hemangioma may need to be treated if it interferes with vision or breathing or is likely to cause long-term disfigurement. In rare cases internal hemangiomas can cause or contribute to other medical problems. The first line treatment option is beta blockers, which are highly effective in the majority of cases. Types
Hemangiomas are benign (noncancerous) vascular tumors, and many different types occur. The correct terminology for these hemangioma types is constantly being updated by the International Society for the Study of Vascular Anomalies (ISSVA). The most common are infantile hemangiomas, and congenital hemangiomas. Infantile hemangiomas
Infantile hemangiomas are the most common benign tumor found in children. They are made up of blood vessels, often called strawberry marks, and are more common in girls than in boys. They usually appear on the skin of infants in the days or weeks after birth. They tend to grow quickly for up to a year. Most then shrink or involute without further problem, however some can ulcerate and form scabs which can be painful.
Lichen scrofulosorum  is a rare tuberculid that presents as a lichenoid eruption of minute papules in children and adolescents with tuberculosis. The lesions are usually asymptomatic, closely grouped, skin-colored to reddish-brown papules, often perifollicular and are mainly found on the abdomen, chest, back, and proximal parts of the limbs. The eruption is usually associated with a strongly positive tuberculin reaction. Of the three tuberculids, the incidence of lichen scrofulosorum was found to be the lowest (2%) in a large study conducted in Hong Kong. This highlights its rarity and significance as an important marker of undetected tuberculosis. See also
