2 (1)Fibrinous pericarditis5 (2)Acute suppurative appendicitis15 (3)Foreign body reaction (pilonidal sinus)22 (4)Granulation tissue30

3 Specific PointWide Area Note: 1)Some cases have photos taken from more than one slide. They may differ a little bit. 2)Not all the features “written in the practical sheet” are shown in the slides, but only the ones important and the ones that I could see. (the best I can do) 1,2,3,..etc Numbers are used in identifying the needed histological layers. Zooming “higher magnification”

4 Inflammatory cells: 1)Lymphocyte 2)Neutrophil 3)Monocyte (macrophage) 4)Eosinophil Fibrobast regenerates collagen. When macrophages unite together the form multinucleated “Giant cells”.
