Lymphangioma circumscription can be healed when treated with a flashlamp pulsed dye laser, although this can cause port-wine stains and other vascular lesions. [15] Orbital lymphangiomas, which carry significant risks from surgical removal, can also be treated with sclerosing agents, systemic medication, or through observation. [16]
Some telangiectasias are due to developmental abnormalities that can closely mimic the behaviour of benign vascular neoplasms. They may be composed of abnormal aggregations of arterioles, capillaries or venules. Because telangiectasias are vascular lesions, they blanch when tested with diascopy.
It often presents in infancy with cardiac failure because of extensive arteriovenous shunting within the lesion.
