Abstract:
The giant fibrovascular polyp of the hypopharynx is a rare and benign tumor. We report one case in a 46-year-old man. This lesion, usually unique, affects predominantly men with an average age of 53 years. These polyps are located predominantly in the upper esophagus and rarely in the hypopharynx. They are usually asymptomatic and small, detected by endoscopy. They can grow to considerable length and cause digestive or respiratory symptoms. Histologically, fibrovascular polyps consist of a various mixture of fibrous and lipomatous elements with abundant vascularisation and they are covered by normal squamous epithelium. The lack of muscular support and the pressure difference in the peristaltic wave contribute to polyp formation.

Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
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,...
Anatomy of Respiratory System I: Upper Respiratory Tract
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
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:
Poliomyelitis
Esophageal Achalasia
