case_images: It measured about 3.5x2.5 cm (Figure 1).
case_images: Microscopic examination. A fine needle aspiration cytology smear shows corrugated keratinous material (A), with a few nucleated and anucleated squamous cells in a background of keratin debris (B). Hematoxylin and eosin-stained microscopic photograph of the incisional biopsy shows corrugated parakeratinized stratified squamous epithelium of uniform thickness with palisaded hyperchromatic basal cell layer and flat junction between the epithelium and connective tissue (C).

case_images: After about half an hour, we fitted and modified the tray on the chairside and provided it to the recipient (Figure 3A, 3B).
case_images: Hematoxylin and eosin-stained microscopic photographs of the excisional biopsy. At low magnification (A) and higher magnification (B), multiple fragments of cystic lining characterized by a uniform thickness of corrugated parakeratinized stratified squamous epithelium and a hyperchromatic and slightly hyperplastic palisaded basal layer are seen.
