Chest computed tomography showed a midesophageal diverticulum projecting rightward at the tracheal bifurcation (Figure 1).
White deposits and residue in the esophagus. (A) Esophagogastroduodenoscopy revealing several white deposits throughout the esophagus. The midesophageal diverticulum was localized on the right wall approximately 30 cm distal to the incisors. White residue was observed at the diverticulum margin and was easily flushed out. (B) In the diverticulum, extensive white deposits were observed and biopsied (yellow circle).

The midesophageal diverticulum was localized on the right wall approximately 30 cm distal to the incisors (Figure 2).
Histopathological findings. (A) Hematoxylin and eosin staining revealed significant inflammatory cell infiltration and acantholytic, finely fragmented squamous epithelial cells. (B) Grocott staining revealed yeast and fungal filaments. Scale bars represent 50 microm.

His-topathological examination (hematoxylin and eosin staining) showed significant inflammatory cell infiltration and acantholytic finely fragmented squamous epithelial cells (Figure 3A), Grocott staining showed yeast and fungal filaments (Figure 3B), and mucosal culture revealed Candida albicans.
