Cystic lesions of the neck

Introduction Lymphangioma is not a true tumor, but a congenital benign sulcus. Tumor-like malformations occur during the development of the embryo during the development of certain parts of the original lymphatic sac that are isolated from the lymphatic system. About half of them existed at birth and more than 90% were found within 2 years of age. The incidence of men and women is roughly the same. Cystic lesions are the most common in clinical practice, accounting for about 3/4, and the rest are seen in the ankle, mediastinum, posterior peritoneum, and pelvis.

1. The cystic mass in the posterior triangle of the neck has the characteristics of spreading to four strokes (upper and lower clavicle, bottom of the mouth, tracheal esophagus and mediastinum), and the boundary is often unclear. More common in infants and young children. It is huge at birth and can grow up gradually.

2. The cystic tumor is soft, generally non-compressive, and can transmit light. The surface of the skin is normal and does not stick.

3. The contents are light yellow transparent or chyle-like, occasionally bloody. A large number of lymphocytes containing cholesterol crystals can be seen under the microscope.

4. Cystoma may have language, breathing or swallowing disorders when it involves the bottom of the mouth, tongue or throat. When the cystic tumor is located on the clavicle, there may be dyskinesia or muscle atrophy when the brachial plexus is compressed. Sometimes the trachea is displaced by pressure.

Differential diagnosis

It should be differentiated from thyroid gland cyst, cleft palate cyst, dermoid cyst, and lipoma.
