A Suspected Palatine Tonsil Tumor Hides an Unrecognized Vagal Schwannoma in a 75-Year-Old Patient: A Case Report

Background. We discuss a particular case of apparent palatine tonsil cancer that was then shown to be vagal schwannoma. Only a few cases of palatine schwannoma have been discussed in the international literature. This case is the first in which a vagal schwannoma manifested itself as a palatine tonsil cancer. Case report. A 75-year-old man reported persistent dysphonia associated with dyspnea in a horizontal position with lateral left decubitus that had started four months prior in the absence of any apparent causes. After conducting clinical examinations and a biopsy, we initiated MRI and CT investigations prior to surgery. We identified the correct diagnosis of vagal schwannoma. After surgery, the patient was resolved completely of his symptomatology, and he retained his nerve function. Conclusion. In some cases, the history and the age of patients can render diagnoses incorrect. We emphasize that rare diseases can mimic other pathologies.
