Key points
Appearance
Hemangiomas can have a variable appearance. They may appear as raised, bright red or purplish bumps on the skin or as deeper, bluish masses. Some hemangiomas are flat, while others are elevated and have a rubbery texture. Their size can range from small to large, depending on the individual case.
Location
Hemangiomas can occur anywhere on the body, but they are most commonly found on the face, scalp, neck, and trunk. Internal organs, such as the liver, can also be affected by hemangiomas, but this is relatively rare.
Growth pattern
Hemangiomas go through two distinct phases – the proliferative phase and the involution phase. During the proliferative phase, which typically lasts several months to a year, the hemangioma grows rapidly. After this phase, it enters the involution phase, where the growth slows down and the hemangioma starts to shrink gradually over time.
Complications
Most hemangiomas are harmless and do not cause any complications. However, in some cases, complications can arise, particularly if the hemangioma is large or located in certain areas (e.g., around the eyes, nose, mouth, neck, extremities or genital area). Complications may include ulceration, bleeding, infection, interference with vision or breathing, or cosmetic concerns.
