A cystic hygroma is a thin-walled, sac-like structure filled with lymph. Cystic Hygroma is fetal malformation of lymphatic vessels, usually around the head and neck. Cystic hygroma form as the result of budding lymphatics and, thus, may occur anywhere in the body, although they are most frequently encountered in the neck (75%) and axilla (20%). After birth, a cystic hygroma usually looks like a soft bulge under the skin. The cyst can't be seen until after birth, and sometimes is not noticed until the person is older. This condition is a congenital (present before birth ) abnormality caused by embryonic lymphatic tissues. Cystic hygromas are tumors derived from these tissues. They are usually slow-growing and may spontaneously resolve or reduce in size. Rapid growth does occasionally occur if there is internal bleeding into the cysts or if there is a complicating infection. The majority of female fetuses with cystic hygroma probably have Turner's syndrome. This, the ultrasound detection of a cystic pouch at the back of the neck is highly suggested of monosmy x.

Sign and Symptoms of Cystic Hygroma
Diagnosis, Treatment, and Cure of Cystic Hygroma
Treatment involves complete removal of the abnormal tissue whenever possible. However, cystic hygromas can often invade other neck structures, making this impossible. Typically, this disorder becomes apparent in infancy or early childhood. Ninety percent of cases are symptomatic by the age of two years. The medical treatment of cystic hygroma includes injection of sclerosing agents and/or steroids. Treat an infection with intravenous antibiotics and perform definitive surgery once the infection has resolved. However, some infected cystic hygromas may improve with use of a sclerosing agent, such as OK-432, which contains penicillin and streptococci.
