ABSTRACT

ABSTRACT: This study described the pathological aspects of a mature intracranial teratoma with meningocele in a one-day-old lamb. The diagnosis of mature teratoma was based on microscopic features, where well-differentiated tissues representative of the three germ layers were observed. The tumor consisted of respiratory, gastrointestinal and urinary epithelium as components of the endoderm; muscle and bone tissues as components of the mesoderm; and keratinized stratified squamous epithelium and adnexa as components of the ectoderm. To the best of our knowledge, this is the first report of intracranial teratoma with meningocele in animals.


RESUMO: Descrevem-se os aspectos patológicos de um teratoma intracraniano benigno com meningocele em um cordeiro de um dia de idade. O diagnóstico de teratoma benigno foi baseado nos achados histopatológicos, com tecidos representativos das três camadas germinativas. O tumor consistia de epitélio respiratório, gastrintestinal e urinário como componentes do endoderma; tecido muscular e ósseo do mesoderma; e epitélio escamoso estratificado queratinizado e anexos como componentes do ectoderma. Com base no conhecimento dos autores, este é o primeiro relato de teratoma intracraniano com meningocele em animais.
