Lymphangioma
Overview
Lymphangioma is a lymphatic malformation, a benign proliferation of lymph vessels, forming a yellowish tumor on the skin, composed of a mass of dilated lymph vessels. It is often removed by a form of surgery using an electric current electrocoagulation for cosmetic reasons. It is rare, incidence being estimated at around one per 10,000 live births. Lymphangiomas are fluid-filled sacs resulting from blockage of the lymphatic system, and are often associated with karyotype abnormalities such as Turner syndrome.
Causes
The reason that these embryonic lymph sacs remain disconnected from the rest of the lymphatic system is not known.[7] Cystic Hygroma is a birth defect.It occurs as the baby grows in the womb from pieces of material that carry fluid and white blood cells. This material is called embryonic lymphatic tissue.After the child is born,cystic hygroma usually looks like a soft bulge under the skin. Sometimes the cyst is not noticeable right after the birth, it may appear later on in the child's life.
Treatment
The treatment for cystic hygroma involves the removal of the abnormal tissue. This can be complicated because this tissue may have invaded other parts in the neck or area where it is found making the procedure almost impossible.Some treatments have been used but only with limited success:chemotherapy medications,injection of sclerosing medications,radiation therapy,and steroids.When cystic hygroma is removed it is most likely to return.
