Exotic bird pathology is an emerging field, needed for an accurate understanding of the biology and disease response of these species. The present paper is aimed to emphasize different lesions in some organs of psittacine cases submitted to necropsy due to sudden death, tumoral disease or metabolic disease. The study was conducted over a two year period (2013-2014) at the Department of Pathological Anatomy from the Faculty of Veterinary Medicine,.Bucharest. Seven psittacine cases, from three different species were submitted to diagnosis. The following organs were submitted to gross and histopathologic examination for each case: lung, heart, liver, kidney, gastro-intestinal tract, spleen and brain. Lesional changes in the organs were classified as: inflammatory, circulatory, necrotic, distrophic and tumoral. The lung presented circulatory lesions in all seven cases and for one case tumoral lesion as well, while the kidney presented both circulatory and necrotic changes in five of the seven cases. The heart was affected in two cases of necrosis, one case of distrophy and one case of tumoral lesion. The liver was affected in two cases by circulatory lesions and one case of inflammatory lesion. The brain was affected in two cases by inflammatory lesions and one case of circulatory injury. The gastro-intestinal tract was affected in one case of necrosis and the spleen, in one case of circulatory lesion. In addition, normal aspects were observed in nine organs, mostly in heart, liver and, spleen. Post-mortem transformation was noticed in 21 organs, mostly kidneys, gastro-intestinal tract, spleen and brain. In conclusion, circulatory and necrotic lesions were frequently encountered in the studied cases. Regarding nonlesional changes in the organs, these appeared with increased frequency, proving the importance.of a rapid diagnosis.
