Congenital lateral cervical cyst, also called branchial cyst, is a relatively rare cystic disease of the neck which presents many problems regarding origin, differential diagnosis, therapy, recurrence, etc.<BR>We report here on 7 congenital lateral cervical cysts which were treated surgically in our clinic from 1979 to 1988 and diagnosed as lateral cervical cysts both clinically and histopathologically.<BR>The patients were 4 males and 3 females aged 17 to 59 years. All had been previously treated in as many as 4 other clinics, and bad been treated by puncture or incision as many as 20 times. Three eases showed inflammation of the upper airway which seemed to be a premonitory symptom of swelling induced by secondary infection. All cases showed painless swelling. Some showed althralgia of the jaw, hoarseness, dyspnca, difficulty in swallowing, and fever from neck swelling that caused secondary infection. We performed total resection in all 7 cases. In 3 of the cases there was adhesion to the internal jugular vein. In 2 case the cyst was accidentally ruptured during the operation. All cysts were on the upper or middle neck as defined by Rickles et al., and were classified as Baily Type II. Histopathologically, all cysts contained lymphoid tissue, and in 5 cases there was the formation of lymph follicles. There was stratified squamous epithelium without keratinization in 5 cases, stratified squamous epithelium with keratinization in one, and mixed cuboidal and squamous epithelium in one.<BR>We discuss the significance of these observations and the problems associated with such patients.
