Symptoms of Congenital Hemangioma
Most congenital hemangiomas are a circle or oval, but they can take any shape. They can be as large as 10 cm, and may range in color from pink to blue to very dark purple. They might look swollen and feel warm to the touch.

There are two types of congenital hemangiomas:

rapidly involuting congenital hemangioma (RICH) - This type of hemangioma shrinks (involutes) without treatment and is mostly gone by the time a child is 12–24 months old.

non-involuting congenital hemangioma (NICH) - This type of hemangioma does not shrink.

A congenital hemangioma that has both types mixed together is called a partially involuting congenital hemangioma (PICH).

A congenital hemangioma will grow as a baby grows, but not at a faster rate than the baby does. This means that the hemangioma will stay roughly the same size relative to the baby's body. This is called proportional growth. A RICH may have some proportional growth before it starts shrinking, but a NICH will continue proportional growth until the child is fully grown.
