Cystic neck disease

Lymphangioma is not a true tumor, but a congenital benign misgrowth tumor. Due to the tumor-like abnormalities that occur when the original lymphatic sac is isolated from the lymphatic system during embryonic development. About half existed at birth, and more than 90% were found within the age of two. The incidence is roughly similar for men and women. Cystic lymphangiomas occur in the neck and are also called cystic hydromas. It is the most common in the clinic, accounting for about 3/4, and the rest is found in the axilla, mediastinum, retroperitoneum and pelvis.
