Figure 3. — ( a) Representative histopathology section of a mucocele showing positively stained macrophages (red arrows), cystic lining (CL) and cystic cavity (CC) (CD68 Immunohistochemistry x400), ( b) High power magnification of CD68+ cells in a mucocele histopathology section. Cytoplasmic vesicles (black arrows) and phagosomes (red arrows) are clearly demonstrated (CD68 Immunohistochemistry x1000), ( c) Representative histopathology section of a symptomatic periapical granuloma showing CD68+ cells which stained brown (black arrows) (CD68 Immunohistochemistry x400), ( d) High power magnification of the larger CD68+ cells showing spongy appearances and wavy cellular outlines which resembled macrophages. Positive immunostaining is located on the cell membrane as well as the cytoplasm. Unstained intracellular vesicles can be identified (black arrows) (CD68 Immunohistochemistry x1000), ( e) High power magnification of the smaller CD68+ cells showing a rounded cellular profile which resembled monocytes (black arrows) (CD68 Immunohistochemistry x1000).
