Vaginal Smear - Metestrus.
Vaginal cytology indicative of metestrus (early diestrus). Note the numerous neutrophils. One or two neutrophils are located within the cytoplasm of intermediate epithelial cells. These cells are termed "metestral cells" and their presence is nearly pathognomonic for metestrus. The majority of epithelial cells are intermediate cells with a few parabasal and a few superficial cells.
