A case of cutaneous angiolipoleiomyoma (angiomyolipoma) in a budgerigar (Melopsittacus undulatus)

Figures & data

Figure 1. Histopathological picture of the budgerigar angiolipoleiomyoma with classical triads—haemangioma, smooth muscle bundles, and mature white adipose tissues—at low magnification. Haematoxylin and eosin. Bar: 2000 µm.

Figure 2. Smooth muscle bundles arranged in well-defined fascicles and around vascular channels. Haematoxylin and eosin. Bar: 100 µm.

Figure 3. Masson's trichrome stained the smooth muscle portions of the mixed mesenchymal tumour bright red, and the collagen blue. Masson's trichrome. Bar: 100 µm.

Figure 4. α-SMA cytoplasmic positivity (brown) in benign neoplastic smooth muscle cells of the angiolipoleiomyoma. Immunohistochemistry, diamino-benzidine–chromogen. Bar: 20 µm.

Figure 5. Sarcomeric actin moderate cytoplasmic positivity (brown) in benign neoplastic smooth muscle cells of the angiolipoleiomyoma. Immunohistochemistry, diamino-benzidine–chromogen. Bar: 20 µm.

Figure 6. Myosin weak cytoplasmic positivity (brown) in neoplastic smooth muscle cells of the angiolipoleiomyoma. Immunohistochemistry, diamino-benzidine–chromogen. Bar: 20 µm.

Figure 7. Claudin-5 membranous positivity (brown) in neoplastic endothelial cells of the angiolipoleiomyoma. Immunohistochemistry, diamino-benzidine–chromogen. Bar: 20 µm.
