Evaluation of accuracy of fine needle aspiration cytology for diagnosis of feline mammary tumours. A: Malignant epithelial cells; nuclei exhibit nuclear criteria of malignancy (variable size, macronucleoli); nuclei superimposed and in different focal planes, together with variation in cell (anisocytosis) and nuclear. (anisocytosis) size are present and abundant vacuoles, May-Graun-Giemsa staining method, 1000X. B: Cytological appearance of spindle shape cells (tomour from the cat n°1) and pleomorphic malign epithelial cells in adenocarcinoma, May-Grünwald Giemsa (MGG) staining method, 1000X. C and D: Myoepithelial cells (spindle shape) with abundant chromatin granules, irregular in shape, and unevenly dispersed throughout nucleus in adenocarcinoma, May-Grunwald-Giemsa, X 400 and X 1000.
