Abstract

Primary respiratory tract neoplasia is uncommon in companion birds or at least there are insufficient reports of cases to make judgements on their risk factors or biological behaviour. In Moluccan cockatoos (Cacatua moluccensis) a primary mucinous adenocarcinoma within the right humerus has been reported in a 13-year-old male and a cystadenocarcinoma protruding from the right axilla and also involving the humerus has also been described. A primary bronchial carcinoma with haematogenous metastasis to the right humerus has been reported in an African grey parrot (Psittacus erithacus) and, as in other animal species, metastatic spread of carcinomas to the lung is possible in birds but is probably even rarer than primary respiratory neoplasia. In this paper we describe the clinicpathological, radiographic and histological features of 4 cases of air sac cystadenocarcinoma that presented as primary causes of respiratory distress in 3 galahs (Eolophus roseicapilla) and a sulphur crested cockatoo (Cacatua galerita). The pathogenesis and diagnosis of these lesions are discussed.
