We report a case of cutaneous angiolipoleiomyoma (angiomyolipoma) found on the anterior wall of the ventral part of the abdomen of a three-year-old female budgerigar (Melopsittacus undulatus). Histologic examination of the well-circumscribed, surgically removed tumour (1.5 cm in diameter) showed a benign admixed proliferation of blood vessels of different size, smooth muscle bundles, and mature adipose tissue, without evidence of malignancy. Endothelial cells of the haemangioma component were positive for claudin-5 endothelium-specific immunohistochemical marker, and the leiomyoma component was positive for α-smooth muscle actin. The differentiated lipocytes showed S-100 protein positivity. The Ki-67 labelling index was 2 to 3%. The mesenchymal tumour was negative for HMB45 melanocytic immunhistochemical marker. To the best of our knowledge, this is the first report describing a cutaneous angiolipoleiomyoma in a budgerigar with histological and immunohistochemical analyses.
