An unusual cause of mechanical dysphagia: an agglomerate of calculi in a tonsillar residue.
We report the case of a 68-year-old man affected by severe oropharyngeal dysphagia for solid food, who had undergone tonsillectomy when he was 22 years old. Videolaryngoscopy revealed a smooth-surfaced, elongated overgrowth on the left lateral pharyngeal wall that protruded toward the left pyriform fossa and impeded the transit of solid boli. A computed tomography scan showed that the solid content of the lesion was markedly inhomogeneous and denser than the surrounding soft tissues. The mass was removed by means of direct pharyngoscopy under general anesthesia. It was found that it arose from the inferior pole of the left tonsillar fossa and had a central cavity filled with caseum and multiple calculi. Histopathologic examination showed that its soft tissue component consisted of lymphoid tonsillar tissue. The operation totally resolved the swallowing disturbance. This case report highlights that tonsilloliths in a tonsillar residue should be considered in the differential diagnosis of mechanical oropharyngeal dysphagia, even in tonsillectomized patients.
