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


Etymology: Gk, branchia, gills, genein, to produce
pertaining to any tissues originating in the branchial cleft or arch. Also called branchiogenous.


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.

TDC should be distinguished from branchiogenic cysts developed close to the midline, solitary cysts in the thyroid gland, hemangioma, cystic lymphangioma and cystic degenerated lymph nodes [7].
Clinically, TDC can often be confused with the low-lying branchiogenic cyst, anterior cyst of thyroid gland or lymphoepithelial cyst [13].

Branchiogenic carcinoma--conceptual or true clinico-pathological entity.
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.
Imaging is generally insufficient to differentiate cystic nodal metastases from primary branchiogenic carcinomas, with both exhibiting soft tissue components associated with a cystic lesion.
31) The presence of in situ carcinoma lesions in the epithelial wall of the branchial cleft cyst in case 1 has also been described in humans (28,32-34) and could represent a link (premalignant lesion) between branchial cysts and primary branchiogenic carcinomas.
10) Cysts of the lateral neck were also believed to be of branchial origin, and in 1912, Wenglowski described the branchiogenic origin of lateral cervical cysts through his work with the human embryo and with cadaver dissection.

This installment of PATHOLOGY CLINIC focuses on cervical cystic squamous cell carcinoma (cSCC), which is commonly misdiagnosed as squamous cell carcinoma arising in a branchiogenic cyst or as a branchiogenic carcinoma.
