Hemangiomas in muscle tissue can develop at any age, but most often occur in young adults. This angiogram image shows a hemangioma deep in the thigh. Hemangiomas in Muscle, Bone, and Internal OrgansĪlthough not as common as hemangiomas of the skin, hemangiomas do develop in other tissues, including muscle and bone. These hemangiomas are fully grown at birth and either completely involute during a baby's first year (called rapidly involuting congenital hemangioma), or they do not involute at all (called non-involuting congenital hemangioma). Hemangiomas that are present at birth (called congenital hemangioma), follow a different growth pattern. In addition, because these tumors can grow to be large and often appear on the face, neck, and scalp, a child's emotional needs must be considered when determining treatment options. However, some hemangiomas can cause problems with vital functions like breathing, eating, and seeing, and require some form of treatment. Most of these hemangiomas will shrink completely on their own and require no treatment. How long it takes for the tumor to reach full-size and then shrink varies greatly, but most infantile hemangiomas have finished involution by the time the child reaches puberty. Girls are affected slightly more often than boys.Ĭommon infantile hemangiomas follow the same growth pattern: a period of rapid growth, often during the first year, followed by a period of tumor shrinkage (called involution or regression). Most infant hemangiomas are capillary hemangiomas, although cavernous and compound types do occur.

They are sometimes present at birth, but most typically appear within the first weeks or months of life.

Hemangiomas of the skin are common in infants. This type of hemangioma is also sometimes referred to as a "pregnancy tumor" because they often appear during pregnancy, typically in the nose and mouth. Because they contain so many blood vessels, they bleed easily - often with just mild contact.

Lobular capillary hemangioma (pyogenic granuloma). These small, red bumps often appear on the hands, face, and arms.

Compound hemangioma. Some hemangiomas are a mix of the capillary and cavernous types.

Like capillary hemangiomas, this type also varies greatly in size and can occur throughout the body. When they develop in the skin, cavernous hemangiomas are often referred to as "deep," and sometimes first appear as a bluish swelling underneath the skin. The blood vessels are not as closely packed as in a capillary hemangioma, and the spaces (or "caverns") between them are filled with blood.

Cavernous hemangioma. In contrast with a capillary hemangioma, a cavernous hemangioma is made up of larger blood vessels that are dilated (widened).

Some appear as a spongy mass that covers an entire extremity (called "diffuse hemangioma" or "angiomatosis"). They can be small or large in size and may be flat to the skin, raised, or protrude out as a nodule. When it develops in the skin, a capillary hemangioma is often referred to as "superficial." Due to their close proximity to the surface of the skin, capillary hemangiomas are typically bright red in color. These capillaries form a tightly packed group held together by thin, connective tissue. It is made up of small capillaries that are normal in size and diameter, but high in number.

Capillary hemangioma. This is the most common type of hemangioma.

Some of the more common types are described below: It is possible to have more than one hemangioma.

A hemangioma occurs when small blood vessels begin to multiply at an abnormal rate and form a mass or lump.
