Intra-esophageal whitish mass - a challenging diagnosis.

Background Whitish intraluminal esophageal masses might represent the endoscopic feature of a bezoar or a pedunculated tumor, most likely a fibrovascular polyp, without exclusion of other mesenchymal tumors (leiomyoma, lipoma, gastrointestinal stromal tumor, leiomyosarcoma, granular cell tumor). If a process of dystrophic calcification is also encountered the differential diagnosis can be a challenge even after histological analysis, as it is highlighted by our case.
