case_images: Microscopic examination revealed acute osteomyelitis with mixed flora, including branching rods and cocci, colonies of filamentous bacteria consistent with Actinomyces, and numerous organisms morphologically consistent with Entamoeba gingivalis (Figure 1(a)). PAS and trichrome stains highlighted the forms morphologically consistent with Entamoeba gingivalis (Figure 1(b)), which were negative for CD68 and CD163 immunohistochemical stains.
