Microscopic findings (with hematoxylin and eosin staining). Histopathological examination of the excised tissue specimen in a) loupe view reveals a pouched appearance with inflammatory infiltration in the stroma. The epithelial lining of the diverticulum is continuous with the surrounding buccal mucosa. The muscle tissue below the lesion is partially observed in the surrounding tissue (black arrow). b) Medium and high magnification (× 100 and × 200) views of the excised specimen show normal buccal epithelium with a collagenous wall and inflammatory cell infiltration
