Case:
A 69-year-old man reported globus sensations since November X and was diagnosed with bilateral pneumonia in December at a local clinic. The patient was subsequently admitted to our hospital for a diagnosis and treatment. His pneumonia improved with antibiotics, but pneumonia recurred. However, pneumonia recurred in February X+1, and antibiotic treatment once again provided relief. However, globus sensations persisted even after the remission of pneumonia. Endoscopic observations revealed a tumor in the hypopharynx, which caused saliva aspiration into the insufficiently closed vocal cords. The hypopharyngeal cancer was treated with chemoradiotherapy, and thereafter, the frequency of aspiration pneumonia decreased.
Conclusion:
The present case illustrated that sometimes aspiration pneumonia may be caused by laryngeal and hypopharyngeal cancer.

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...
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,...

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:
