Lymphangiomatous polyps are non‐neoplastic developmental lesions comprised of tissue elements native to the nasopharynx and categorised as hamartoma. Lyphangiomatous polyp of tonsil is a kind of hamartomatous lesion that has been described by different nomencultures such as lymphangietatic fibrous polyp, polypoid lymphangioma of the tonsil, hamartomatous tonsilar polyp, pedunculated squamous papilloma and so on. The pedunculated polyps of the palatine tonsil are relatively rare. Because of the unusual clinical and pathological features of these polyps, pathologists and clinicians alike may have difficulty in classifying them correctly. Various symptoms associated with these polypoid masses are acute tonsillitis, recurrent sore throat, blood in sputum, dysphagia, mass in throat, slowing deglutition and lump in throat. Microscopically, it is lined by squamous epithelium and its stroma is composed of variably loose or more dense collagenous tissue and adipose tissue, usually containing dilated lymphatic channels and various components of lymphoid tissue. In this report we present our experience on a case of lymphangiomatous polyp of tonsil.
A 32‐year‐old woman was admitted to Imam Reza Hospital with a polypoid and painful oral cavity mass on the upper lobe of the right pharyngeal tonsil which had been present for 2 months. The patient underwent a right tonsillectomy. She had the following symptoms: recurrent and acute one‐sided tonsillitis, recurrent sore throat, sensation of foreign body, halitosis, sleep apnea, shortness of breath and snoring. She was not a smoker with any previous history of surgery or treatment. The physical examination revealed cervical lymphadenopathy.
Grossly it was a 2.8×2.5×1.8 cm, firm polypoid mass that was attached to the tonsil. The cut surface was a creamy soft tissue. Histologicaly the polyp was covered by squamous epithelium with hyperkeratosis and its stroma was composed of dialated lymphatic vascular channels, varying amounts of fibrous connective tissues and aggregates of lymphoid tissues.
