Histopathology of erosion caused by CPA. a Cavity [§] is covered by ciliated epithelium without erosion (H-E). Note the Splendore-Hoeppli phenomenon (eosinophilic staining in fungus ball [†]). b Immounohistochemical staining for cytokeratin AE1/AE3 is done in case A. Erosion ratio is 3.7 %. c Epitheliums disappear and inflammatory granulation tissue exposes the surface of cavity. d Immounohistochemical staining for cytokeratin AE1/AE3 is done in case A. Erosion ratio is 95.3 %
