Dramatic presentation of a giant fibrovascular polyp of Laimer's triangle

Hypopharynx giant fibrovascular polyps

“…According to the Ramalho et al's report [4], showed that the average age for FVP to occur is 57.5 years. Where 64% of patients had dysphagia, 31% of patients had respiratory symptoms and 41% of patients suffered from esophagus reflux [3,4]. Furthermore, many papers reported that FVP is one of the causes of sudden onset of suffocation [4,6,7].…”

“…Moreover, small polyps can often be mistaken for normal structures so that the further radiological evaluation may be essential for early diagnosis. Many cases were inexpertly diagnosed during routine thoracic CT or MRI imaging for other purposes [3,8]. The pathologic feature of FVP is the presence of different proportions of vascular structure, fibrous andadipose tissue, covered with normal mucosa, which demonstrated inhomogeneous signals on contrast enhancement CT or MRI [9][10][11].…”

“…The hypopharyngeal FVP usually originated from Killian dehiscence (the area between the superior and inferior cricopharyngeal muscles) or Laimer-Haeckermann area triangle (area between the inferior cricopharyngeal muscle and the proximal end of the esophagus) [2]. Due to weakness of muscles and the pressure during eating, loose mucosa prolapsed by gravity and elongate endoluminally from continuous peristaltic movements, leading to the mucosal and submucosal nodules valgus fold thickening and subsequent proliferative lesions [2,3]. Because of the dormant origination and the nature of slow growth [4], hypopharyngeal FVP is often asymptomatic and overlooked for years.…”
