The aspirate was taken 5 days after the photograph in Figure 1, when the lesion was 5–6 mm in diameter. There is a mixed population of inflammatory cells composed of toxic and degenerating neutrophils, and phagocytically active macrophages. Rare lymphocytes, plasma cells, and red blood cells are also present. (Modified Wright-Giemsa stain, high power magnification).
