Teratomas are defined as germ cell origin neoplasms that can be rarely found in either humans or animals. Their most common localization is the gonads, although extragonadal localization has also been observed. In avian medicine, there is scarce literature about the occurrence of teratomas and their clinical implications, and this is mainly in wildlife birds . For this reason, we report the first description of a teratoma with both retrobulbar and intracranial locations in a 10-day-old chick of… Expand
Ocular teratoid medulloepithelioma in a northern red-shouldered macaw: case report and literature review
TLDR
A 4-mo-old northern red-shouldered macaw was admitted to the veterinary hospital of the Arruda Câmara Zoo, in the State of Paraiba, Brazil, for investigation of an orbital mass, and was euthanized, and an autopsy was performed. Expand
Brain teratoma in a free-ranging mallard (Anas platyrhynchos) ˗ case report
ABSTRACT Teratoma is a rare neoplasia with differentiation in two or three germ cell lines. Intracranial teratoma in birds has rarely been reported, especially affecting the brain. This is the firstExpand
Retrobulbar adenocarcinoma in an Amazon parrot (Amazona autumnalis)
TLDR
A retrobulbar mass creating exophthalmia and neurologic signs in a red-lored Amazon parrot is described, which was diagnosed as an adenocarcinoma. Expand
Extragonadal teratoma in a domestic turkey (Meleagris gallopavo domestica)
TLDR
This is the first report of a primary, spontaneous and, most probably, congenital teratoma in a domestic turkey, localized in front of the left eyeball, and the proliferative activity of the tumour cells was confirmed using proliferating cell nuclear antigen immunostaining. Expand
Recurrent Subcutaneous Teratoma in an Adult Red-crowned Amazon Parrot (Amazona viridigenalis)
TLDR
An approximately 42-year-old, wild-caught, red-crowned Amazon parrot was evaluated for a subcutaneous mass to the right of the keel, diagnosed as a teratoma with stratified squamous epithelial and neuroectodermal components. Expand
Ovarian Teratocarcinoma in an Emu (Dromaius novaehollandiae): Histopathological and Immunohistochemical Characterization.
TLDR
A 17-year-old female emu (Dromaius novaehollandiae) was presented for clinical evaluation due to a 3-week history of anorexia and progressive weight loss and died after sedation, confirming the diagnosis of teratocarcinoma. Expand
Intracoelomic Teratoma in an Eclectus Parrot (Eclectus roratus)
TLDR
Histopathologic examination of submitted tissue from the mass with immunohistochemistry revealed mixed populations of neoplastic cells differentiated from 3 primordial germinal layers, confirming the diagnosis of teratoma. Expand
COELOMIC TERATOMA IN A BLUE-AND-YELLOW MACAW (ARA ARARAUNA)
TLDR
This study is the first, to the authors' knowledge to report a case of a teratoma in a blue-and-yellow macaw, which was theorized to have originated from Meckel's diverticulum. Expand

TLDR
The author propounds the following hypothesis: intracranial dysembryogenetic tumors composed of cells resembling the cells that appear in the earlier stages of embryogenesis are more malignant than those composed ofcells resembling those appearing in the later stages of embryos. Expand
Intracoelomic Teratoma in a Juvenile Bald Eagle (Haliaeetus leucocephalus)
TLDR

Sex chromosome determination in extragonadal teratomas by interphase cytogenetics: clues to histogenesis.
TLDR
The data do not support the theory of parthenogenetic EGT development, at least in males, and strongly suggest that EGTs arise from pluripotent diploid precursor cells, for example, either premeiotic germ cells that have not yet undergone the first meiotic division or pluripoline embryonal or extraembryonal cells.
