“…These tumors occasionally become large, as was the case here, and cause obstructive symptoms and sometimes present as bilateral (4,5,9). The reported cases have mostly been in adults with only a few exceptions (2)(3)(4)(5)(6)(7)(8). The present case also expressed that he had experienced occasions of bloody saliva, especially after meals.…”

“…Lymphangiomatous polyps generally present as a pale or pink pedunculated lesion attached to the palatine tonsil. They consist of dilated amorphous lymphatics with fibrous, lymphoid, and/or adipose stroma, and they are considered to be a hamartoma or, to some authors, an acquired lymphangiectatic malformation (3)(4)(5)(6)(7). Because of the eccentric histopathological features of these polyps, there is still difficulty in describing them with a common terminology and in classifying them correctly.…”

Lymphangiomatous polyps are rare benign hamartomatous tumors of the palatine tonsils that can cause significant distress to the patients such as sore throat, foreign body sensation, a lumpy feeling in the throat region, dysphagia, and eventual suffocation. In this paper, the case of a 17-year-old male who came to the outpatient clinic with a complaint of difficulty in swallowing, eventual vomiting, and occasions of hematemesis is presented. On physical examination, the patient had a smooth-surface, polypoid, pedunculated tumoral lesion originating from the middle pole of the left palatine tonsil and protruding into the oropharyngeal isthmus. The patient underwent left tonsillectomy. Histopathological examination of the surgical specimen showed typical features of a lymphangiectatic fibrolipomatous polyp. The case reported herein with the brief literature review points out the clinical and the benign, non-neoplastic characteristics of the lymphangiectatic fibrolipomatous polyp, which can be cured by surgical excision along with tonsillectomy.

“…The dilated appearance of the lymphatic channels along with the fact that tonsils possess only efferent lymph vessels led us to verify if inflammatory hyperplasia with obstruction of lymphatic channels could be a contributing factor for the polyp formation [5]. Nevertheless, no evidence of lymphatic obstruction was found in the polyps or in the tonsils removed along with the lesion, even after serial sectioning of the tissue specimens.…”

Immunohistochemical study of stromal and vascular components of tonsillar polyps: high endothelial venules as participants of the polyp’s lymphoid tissue

et al. 2011

Tonsillar polyps are nonneoplastic lesions usually composed of variable amounts of lymphoid and vascular and connective tissues. All of them are generally assumed to be hamartomatous proliferations, but the profile of vascular and connective components has yet to be explored. The vascular system of the tonsils is complex and includes highly specialized structures (i.e., high endothelial venules (HEVs)) involved in lymphocyte homing into lymphoid tissues. In 14 tonsillar polyps and 26 control tonsils, an immunohistochemical study was performed using CD34 (blood vessels and HEVs), MECA-79 (HEVs), D2-40 (lymphatic vessels), Ki-67, collagens I and III, fibronectin, and tenascin-C. The polyps showed increased total lymphatic area, whereas the number of blood vessels and lymphatics and the blood vascular area did not differ significantly from those of control tonsils. Rare Ki-67+ endothelial cells were found. In the polyps, we detected, possibly for the first time, HEVs amid lymphoid tissue, and that the amount of the latter correlated positively with HEV density. The polyps also presented lesser amounts of fibronectin and collagens I and III than in normal tonsils, which were distributed in a disorganized fashion. Tenascin-C expression was uncommon in the polyps and control tonsils. Tonsillar polyps are composed of disorganized connective tissue and lymphatic channels which can be considered hamartomatous proliferations. However, the lymphoid component is possibly reactive due to its relationship with the HEVs. The highly differentiated phenotype of the HEVs and their complex biology are not in agreement with what would be expected for a component of hamartomatous nature.

“…Since Kardon et al 1 study in 1999, we found and reviewed 7 articles in their entity that were relevant to our search. [2][3][4][5][6][7][8] Eight patients were identified as having a diagnosis of LAP of palatine tonsil. Table 1 provides a comparison between the 2 groups (Kardon et al data versus published articles since 1999).…”

“…One is that there was a case that occurred in bilateral palatine tonsil and the other is that complete removal through tonsillectomy was more used than excisional in the treatment. [2][3][4][5][6][7][8] Lymphangiomatous polyp of the palatine tonsil usually occurs in young adults and children and does not appear to have a gender predilection. [1][2][3][4][5][6][7][8] The pathogenesis of LAP of the palatine tonsil is not clearly known, but 2 hypotheses have been proposed.…”
