Peripheral Nerve Sheath Tumours in Cattle
Samples of morbid bovine tissues obtained from slaughterhouse were submitted to histopathological examination. Neoplastic growth within the peripheral nerves was observed microscopically, with the presence of Antoni A and Antoni B patterns, and sporadically Verocay bodies. Additionally, immunohistochemical examination of the sections revealed positive reaction to vimentine, neuron specific enol...

متن کاملImpaired Pten Expression in Human Malignant Peripheral Nerve Sheath Tumours
Malignant peripheral nerve sheath tumours (MPNST) are aggressive sarcomas that develop in about 10% of patients with the genetic disease neurofibromatosis type 1 (NF1). Molecular alterations contributing to MPNST formation have only partially been resolved. Here we examined the role of Pten, a key regulator of the Pi3k/Akt/mTOR pathway, in human MPNST and benign neurofibromas. Immunohistochemis...
متن کاملThe ultrastructure of bovine peripheral nerve sheath tumours.
Bovine peripheral nerve sheath tumours from 30 cattle were similar ultrastructurally to human schwannomas and neurofibromas. Bovine neurofibromatous tissue had large amounts of extracellular material, primarily collagen and electron lucent granular material. The principal cells had basal laminae and a disorganized proliferation of the plasmalemma. Axons were consistently seen and were surrounde...
متن کاملCentral Mandibular Nerve Sheath Myxoma
Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement...
