It has been known since the writings of Roser that certain cysts ofthe neck originate in the incomplete closure of branchial clefts and he described the branchial cyst, in which the internal and external openingswere closed, the intermediate portion becoming cystic and the cysticfistula in which one end remains open. Branchial cysts develop or becomeapparent at or about puberty or even the 3rd. and 4th. decade of life, butare congenital, because they develop upon a matrix of congenital cyst contents are of epithelial origin and we may speak of mucous,serous and atheromatous cysts. Dermoid cysts contain the characteristicsecretions of the skin and its appendages; the branchial contain theproducts of the epithelial cells, because their walls do not contain anyhair follicles, sebaceous or sweat glands, as the branchial clefts close be-fore these appendages are formed. Branchio-genetic cysts form but avery small proportion of the tumors broadly designated as cystic tumors.
