Fibromatous polyp of the hypopharynx.
We treated a patient with hypopharyngeal fibromatous polyp and speculated the mechanism of this disease. Fibromatous polyp, consisting of fibrous tissue hyperplasia with small vessels, fatty cells and inflammatory cells, is a clinically diagnostic name. Most of pharyngeal fibromatous polyps are arising from the palatine tonsil, and those from the pharyngeal epithelium are rare. The greater part of hypopharyngeal tumors is squamous cell carcinomas, and benign tumors are really uncommon. Fibromatous polyp is not thought to be a true tumor, but the symptoms are almost the same as tumorous diseases, e.g., discomfort in the throat, swallowing difficulty and respiratory distress. Complete resection is used as the treatment method. We operated on this patient under a laryngoscope and successfully resected the polyp. Five months after the operation, there is no sign of recurrence and the patient has no symptoms. This type of polyp is considered to enlarge gradually and it can cause asphyxia and/or dysphagia, so complete ablation should be performed as soon as possible.
