Vascular, Lymphatic and Systemic Conditions

A hemangioma is a mass comprised of tangled blood vessels and connective tissue. Congenital hemangiomas are present at birth. Capillary hemangiomas are the most common type of hemangiomas. They are a bright red color. Cavernous hemangiomas are comprised of larger, dilated blood vessels. The blood vessels stretch and pool with blood, hence they are termed "cavernous." A hemangioma that is comprised of both capillary and cavernous types is known as a compound hemangioma. Congenital hemangiomas typically disappear within months to years.
