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.
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
Segmental hemangiomas are larger, and appear to encompass a region of the body. Larger or segmental hemangiomas that span a large area can sometimes have underlying anomalies that may require investigation, especially when located on the face, sacrum, or pelvis. Unless ulceration occurs, an IH does not tend to bleed and is not painful.

Infantile hemangioma is the most common vascular tumor. It is a benign tumor, which occurs in 4-5% of Caucasian infants, but rarely in dark skinned infants. [6] It occurs in 20% of low weight premature infants and 2.2 to 4.5 times more frequently in females. [7]
A pyogenic granuloma or lobular capillary hemangioma [3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. [4] [5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh. [6]
Targetoid hemosiderotic hemangioma manifests as a single, tiny, reddish-violaceous to brown targetoid lesion that can grow centrifugally in the acute phase is encircled by a hemorrhagic halo. [3] The halo may vanish in later phases, leaving just a central papule. [4] [5] There have been reports of certain cases without targetoid development. [6]
Bowel intussusception can occur with various benign colonic tumors.
