Information about lymph vessel tumors, know as cystic hygroma or lymphangioma

Introduction to Cystic Hygroma (lymphangioma)

A cystic hygroma, otherwise known as a 'lymphangioma' is a very rare condition, where a tumour usually present from birth, develops just underneath the skin especially in the neck, and more rarely in the armpit region. The tumour consists of a collection of abnormal lymph vessels.

Lymph is a milky body fluid which contains certain white blood cells (lymphocytes), proteins and fats. This lymph collects outside the blood vessels, but has it's own drainage system, called the lymphatic system, which flows back into the blood stream via lymph vessels. These vessels can develop abnormally becoming grossly enlarged to produce `cystic hygromas'. Lymph is an extremely important part of the bodys immune system, and it is also involved in absorption of fats into the circulation from the intestine.

A cystic hygroma is benign; it is not a cancer or malignant tumour, and therefore does not spread to other parts of the body nor does it become a life threatening condition. A cystic hygroma is a soft swelling, usually resembling a bunch of small white grapes. The swelling can become very large, quite unsightly and very disturbing to parents of the affected child.

This cystic swelling is usually allowed, when possible, to grow with the child and then, it is removed surgically when the child is about 5 years old.

Apart from affecting the side of the neck this condition may also affect the lips (where it is known as macrocheilia enlarged lips) or the tongue (known as macroglossia enlarged tongue). Occasionaly a cystic hygroma remains stationary in size for long periods, but more often than not it increases rapidly in size, and therefore will need to be removed surgically.
