Angiofibroma in a Cockatiel (Nymphicus hollandicus)

Publication date: Available online 26 February 2015 Source:Journal of Comparative Pathology Author(s): G.A. Doss , J.L. Miller , H. Steinberg , C. Mans Human angiofibromas are rare and arise typically in the nasopharynx. In veterinary medicine they have only been described in the dog. Microscopically, angiofibromas consist of irregular groups of blood vessels within a stroma of connective tissue, with oedema and secondary inflammation often present. A cockatiel (Nymphicus hollandicus) was presented with an oral mass that consisted of aggregates of blood vessels surrounded by a connective tissue stroma, with the presence of oedema and secondary inflammation. Tumours of the oral cavity are uncommon in birds and to the authors' knowledge this is the first case of avian angiofibroma.
