Abstract
Acute pharyngitis is a common disease. However, acute pharyngitis caused by Klebsiella pneumoniae with a gross appearance mimicking hypopharyngeal malignancy has never previously been reported. We report the case of a 57-year-old man with a right hypopharyngeal tumor which was disclosed by fiberoptic laryngoscopy and computed tomography scan. However, both the frozen and final pathologies showed no evidence of malignant cells, and a bacterial culture revealed the growth of K. pneumoniae. The hypopharyngeal lesion completely regressed after 2 weeks of antibiotic treatment. Clinicians should perform biopsy along with tissue culture for tumor-like lesions because infectious agents can lead to lesions with malignancy-like appearance.
