Histopathological microphotographs of our case of periapical granuloma with actinomycosis. (A) Low-power microphotograph showing an inflamed fibrous connective tissue and an actinomycotic colony. (B and C) Medium- and high-power microphotographs exhibiting foci of hemorrhage and a severe lymphoplasma cell infiltrate in a vascularized fibrous connective tissue. (D) Medium-power microphotograph showing an actinomycotic colony with significant variations in the color between the center and periphery of the colony. (E and F) Medium- and high-power microphotographs of an actinomycotic colony exhibiting pale blue and red radiating filamentous bacteria at the center of the colony and deep blue filamentous bacteria arranging in a characteristic sun-ray pattern at the peripheral part of the colony. The actinomycotic colony was surrounded by both acute and chronic inflammatory cells. (Hematoxylin and eosin stain; original magnification; A, 2×; B, 20×; C, 40×; D, 10×; E, 20×; F, 40×).
