ABSTRACT: Introduction Fibrovascular polyps (FVPs) are rare benign tumors originating in the cervical esophagus, and, rarely, in the hypopharynx. A case of FVP from the larynx has not yet been described in the literature. Objectives To discuss a unique case of FVP originating in the larynx. Resumed Report A 58-year-old woman presented with a 6-month history of progressive dysphagia. Endoscopic exams identified an elongated polypoid lesion originating from the mucosa of the epiglottis and the right pharyngoepiglottic fold. Excision of this mass under direct laryngoscopy revealed an 11.5 × 0.8-cm polypoid lesion, histologically diagnosed as an FVP. Conclusion The location of this FVP is important because, despite being a benign tumor, it carries a potentially lethal risk of upper airway obstruction.
Project description:Giant polyps in the esophagus are rarely occurring benign tumors and may contain lipomas, fibrovascular polyps, fibrolipomas or neurofibromas polyps. Clinical symptoms include dysphagia, vomiting, retrosternal pain, shortness of breath, and asthma. In some cases, the polyps are regurgitated into the oral cavity and represent a spectacular manifestation. The reported case in this study was of a 50-year-old man who complained of emesia for half a year and dysphagia for one month before being hospitalized. Occasionally, a fleshly mass reached into his mouth. The results of endoscopic ultrasonography, barium swallow in the upper digestive tract, and a computed tomography scan demonstrated a giant polyp in the esophagus, which was subsequently removed by gastroscopy. Pathological examination determined a fibrovascular polyp.
Project description:Fibrovascular polyp of the cervical esophagus represents about 0.5% to 1% of all benign oesophageal tumours. Usually asymptomatic, when FP protrudes into the oesophageal lumen, this may cause respiratory obstruction and provoke dysphagia, vomiting, dyspnoea, and retrosternal pain. In this article, we describe a multimodal approach in the treatment of a complex recurrent FP, for which surgical resection represents the safer and less invasive procedure.
Project description:Esophageal fibrovascular polyp is rare in esophageal neoplasms and usually very large. Here, we present a case of giant esophageal fibrovascular polyp. The patient had dysphagia and choking sensation at presentation. She underwent positron emission-computed tomography (PET-CT), endoscopy, endoscopic ultrasonography, and fine needle aspiration. She was clinically diagnosed as having an esophageal benign tumor and underwent endoscopic submucosal dissection. The polyp was successfully resected; however, the process was very difficult, and the lesion was too large to pass through the upper esophagus. Finally, we removed the lesion surgically. Fibrovascular polyps are often large, and if endoscopic resection is chosen, it is necessary to consider the difficulties that may be encountered during resection, before initiating treatment.
Project description:In this study, 23 subjects produced cyclic transitions between rounded vowels and unrounded vowels as in /o-i-o-i-o-…/ at two specific speaking rates. Rounded vowels are typically produced with a lower larynx position than unrounded vowels. This contrast in vertical larynx position was further amplified by producing the unrounded vowels with a higher pitch than the rounded vowels. The vertical larynx movements of each subject were measured by means of object tracking in laryngeal ultrasound videos. The results indicate that larynx lowering was on average 26% faster than larynx raising, and that this velocity difference was more pronounced in woman than in men. Possible reasons for this are discussed with a focus on specific biomechanical properties. The results can help to interpret vertical larynx movements with regard to underlying neural control and aerodynamic conditions, and to improve movement models for articulatory speech synthesis.
Project description:Intussusception is common in infants and young children. The most common type is small intestinal intussusception or ileo-colic intussusception. Colonic intussusception is rare. Intestinal polyps, especially large polyps or multiple polyps, can cause intussusception. Here, we report a rare case of colo-colic intussusception caused by a giant juvenile polyp of sigmoid colon, and the patient achieved good clinical effect through polypectomy under colonoscopy. So, when children have colonic intussusception, the possibility of colonic polyps should be considered.
