Klebsiella pneumoniae pharyngitis mimicking malignancy: a diagnostic dilemma
1Department of Otolaryngology, Taipei Veterans General Hospital, No. 201, Sec. 2, Shipai Rd, Taipei, 11217, Taiwan, R.O.C.
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.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Pneumonia I: Introduction
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Pneumonia I: Introduction
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
