branchiogenic

bran·chi·o·gen·ic

, branchiogenous (brang'kē-ō-jen'ik, -kē-oj'en-ŭs),
Originating from the pharyngeal (branchial) arches.
[G. branchia, gill, -gen, to produce]

branchiogenic

[brang′kē·ōjen′ik]
Etymology: Gk, branchia, gills, genein, to produce
pertaining to any tissues originating in the branchial cleft or arch. Also called branchiogenous.

branchiogenic

adjective Referring to or arising from the human anlage of gills, the branchial cleft or arch.

branchial, branchiogenic, branchiogenous

pertaining to, or resembling, gills of a fish or derivatives of homologous parts in higher forms.

branchial arches
paired arched columns that bear the gills in lower aquatic vertebrates and which, in embryos of higher vertebrates, become modified into structures of the face, mandible, ear and neck.
branchial clefts
the clefts between the branchial arches of the embryo, formed by rupture of the membrane separating corresponding entodermal pouch and ectodermal groove.
branchial cyst
a cyst formed deep within the neck from an incompletely closed branchial cleft, usually located between the second and third branchial arches. The branchial arches develop during early embryonic life and are separated by four clefts. As the fetus develops, these arches grow to form structures within the head and neck. Two of the arches grow together and enclose the cervical sinus, a cavity in the neck. A branchial cyst may develop within the cervical sinus. Called also branchiogenic or branchiogenous cyst. Seen rarely in dogs as a slowly developing swelling in the pharyngeal area, filled with saliva.
branchial groove
an external furrow lined with ectoderm, occurring in the embryo between two branchial arches.

The purpose of this overview is to summarize the current concept of carcinomas arising in branchial cleft cysts (so-called, branchiogenic carcinoma), indicating that most, if not all, represent cystic metastases from oropharyngeal squamous cell carcinoma primaries.
