A retrospective study of neoplasms in ornamental and pet birds diagnosed at the Hospital de Aves of the Universidad Nacional Autónoma de México (2007-2014)

Abstract

A retrospective study including a total of 44 ornamental and pet birds with neoplasms diagnosed at the Hospital de Aves, Facultad de Medicina Veterinaria y Zootecnia, Universidad Nacional Autónoma de México from January 2007 to April 2014 was conducted. Most of affected birds were Psittaciformes (n=26, 59%) including budgerigars (Melopsittacus undulatus) (n=12/26, 46.15%) and amazon parrots (Amazona spp.) (n=7/26, 26.92%), and followed by Passeriformes and Anseriformes (n=7/44, 15.90%, each) and Galliformes (n=4/44, 9.09%). The youngest studied bird was a 6.5-week-old lovebird (Agapornis sp.) with a papilloma, and the oldest bird was a 37-year-old yellow-naped parrot (Amazona auropalliata) with a hemangiosarcoma. Most of the affected birds were adults (n=23, 52.27%). The gender was determined for 17 birds (38.63%), of which eight (47.05%) were females and nine (52.94%) males. There were 45 reported neoplasms, as one salmon-crested cockatoo (Cacatua moluccensis) had two neoplasms. The two most frequent neoplasms were fibrosarcomas (n=9/45, 20%) and hemangiosarcomas (n=5/45, 11.11%). The largest number of neoplasms was found in the integumentary system (n=18/45, 40%), followed by the reproductive system (n=10/45, 22.22%). Of the 16 types of neoplasms, seven (43.75%) were malignant, six (37.5%) were benign, and three (18.75%) were potentially malignant. This study showed similarities with retrospective previously reported studies and contributes to the knowledge of the neoplastic diseases that occur in ornamental and pet birds in Mexico.

Laryngeal and oropharyngeal adenocarcinoma with pulmonary metastases in a common raven (Corvus corax)

“…Papillomavirus and Psittacid Herpesvirus-1 have been suggested as some of the ethiologic agents of IPP 11 12 13 . There are also some cases of papillomatosis described in passerines such as finches and canaries 14 15 . In the present case, inclusion bodies suggestive of viral infection were not seen histologically.…”

Osteoma in Agapornis roseicollis

“…https://doi.org/10. 21708/avb.2022.16.4.11208 CLINICAL REPORT a 2-year-old Canarium, affecting the musculoskeletal system, but no further information about the location was available (SÁNCHEZ-GODOY et al, 2020). Recently there was a case of bilateral osteoma cutis in a Peach-Faced Lovebird secondary to trauma (PINZÓN-OSORIO et al, 2020).…”
