hemangioma

 [he-man″je-o´mah]
a congenital vascular malformation consisting of a benign tumor made up of newly formed blood vessels clustered together; it may be present at birth in various parts of the body, including the liver and bones. In the majority of cases it appears as a network of small blood-filled capillaries near the surface of the skin, forming a reddish or purplish birthmark.
cavernous hemangioma a congenital vascular malformation that has a soft, spongy consistency and may contain a large amount of blood. It usually appears during the first few postnatal weeks and disappears by the age of 9 years. The most common sites are head, neck, and viscera such as the liver, spleen, or pancreas. Treatment varies according to the size of the lesion.
strawberry hemangioma a circumscribed capillary hemangioma, which may be present at birth or may appear soon after birth. These are most common on the head, neck, and trunk and appear as small macules that develop into raised purplish-red lobulated tumors. Most involute by age 2 to 3.

cav·ern·ous he·man·gi·o·ma

old term for deep cutaneous hemangioma with dilated vessels on gross and microscopic examination. Also used incorrectly for venous malformation.

cavernous hemangioma

Etymology: L, caverna, hollow place; Gk, haima, blood, oma, tumor
a benign, congenital red or purple tumor consisting of enlarged blood vessels. The scalp, face, and neck are the most common sites, but these tumors have been found in the liver and other organs. Superficial cavernous hemangiomas are friable and easily infected if the skin is broken. Treatment includes observation, irradiation, sclerosing solutions, and laser surgery and excisional surgery. Also called angioma cavernosum, cavernoma. Compare capillary hemangioma, nevus flammeus.

cav·ern·ous he·man·gi·o·ma

(kav'ĕr-nŭs hē-man'jē-ō'mă)
A vascular malformation containing large blood-filled spaces, due apparently to dilation and thickening of the walls of the capillary loops; in the skin, extends more deeply than a capillary hemangioma and is less likely to regress spontaneously.

HEMANGIOMA BENEATH THE RIGHT EYE
A benign tumor found on the skin or in an internal organ, composed of dilated blood vessels, and often encapsulated within a fibrous shell. Synonym: cavernous hemangioma See: illustration

cavernous hemangioma

Hemangioma.

infantile hemangioma

A dull red benign lesion, usually present at birth or appearing within 2 to 3 months thereafter. This type of birthmark is usually found on the face or neck and is well demarcated from the surrounding skin. It grows rapidly and then regresses. It is caused by a proliferation of immature capillary vessels in active stroma. Synonym: strawberry hemangioma; strawberry mark; strawberry nevus (2)

Treatment

If removal is necessary, plastic surgical excision using the carbon dioxide, argon, or potassium titanium oxide phosphate laser is effective in ablating this lesion.

CAUTION!

The use of laser treatment necessitates observance of all laser safety precautions.

lobular capillary hemangioma

A fleshy, polyp-shaped hemangioma that may develop at the site of a wound. It bleeds easily and is usually tender.

strawberry hemangioma

Infantile hemangioma.

cavernous

pertaining to a hollow, or containing hollow spaces.
