1/44. Giant fibrovascular polyp of the esophagus: CT and MR findings.We present a case of giant fibrovascular polyp of the esophagus with predominant fat contents. Both computed tomography (CT) and magnetic resonance imaging (MRI) findings of this rare tumor are reported. The employment of CT and MRI in the presurgical evaluation of fibrovascular esophageal polyp is suggested.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/44. Giant fibrovascular polyp of the oropharynx.We describe a case of a giant fibrovascular polyp arising from the oropharynx and causing vague clinical symptoms. To our knowledge, this is the first description of an oropharyngeal fibrovascular polyp reported in the medical literature. The diagnosis was based on MR imaging findings, which showed the size and configuration of the polyp as well as the site of attachment. The patient underwent surgery, and the diagnosis was confirmed histologically.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/44. Double ileoileal intussusception caused by a giant polypoid mass of heterotopic pancreas in a child.Heterotopic pancreatic tissue has been found in several abdominal and intrathoracic locations. In the ileum, it is a rare, usually asymptomatic, incidental finding. CONCLUSION: A unique case of a recurrent ileoileal intussusception in an 11-year-old girl is presented caused by a giant polypoid mass composed of ectopic pancreatic tissue that remained undetected during several diagnostic tests during two previous admissions and laparoscopic abdominal exploration.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
4/44. Fibrovascular esophageal polyp as a diagnostic challenge.Fibrovascular polyps are rare benign esophageal tumors that usually arise from the proximal third of the esophagus. We present the case of a 48-year-old man with a history of dysphagia and 7-kg weight loss over a period of 2 months. A barium swallow showed a distended esophagus with a tumor extending from the upper esophageal sphincter to the cardia. On a thoracic computed tomographic scan, a homogeneous intramural mass with a density of 22 Hounsfield units was seen, which extended throughout the entire esophagus. Fiberoptic endoscopy confirmed the presence an intramural tumor beginning at the upper esophageal sphincter and reaching to the cardia. The tumor was completely covered with mucosa, except for an ulcerated area at its distal end, which herniated into the stomach. On endoscopic ultrasound, the tumor appeared to grow submucosally and to respect the muscularis propria. Endoscopic biopsies from the ulcerated distal aspect of the tumor suggested a leiomyoma. None of the imaging modalities used revealed evidence of a polyp or intraluminal esophageal tumor. Rather, a potentially malignant extensive intramural tumor was suspected, and an esophagectomy was performed. Only at the time of removal of the specimen did it become evident that the tumor mass was located intraluminally with a pedicle in the region of the upper esophageal sphincter. The final pathological diagnosis was a giant fibrovascular polyp of the esophagus.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
5/44. Recurrent esophageal fibrovascular polyps: case history and review of the literature.Fibrovascular esophageal polyps are rare benign tumors. They can grow to considerable length and cause symptoms such as dysphagia, retrosternal discomfort, vomiting, and even asphyxia. A barium contrast esophageal radiography will show a filling defect compatible with an esophageal mass. Surgical removal through cervical esophagotomy is the preferred treatment, and recurrences after surgery are rare. We describe a patient who developed three recurrent giant fibrovascular esophageal polyp within eight years. A review of the literature is given.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/44. Protruding giant cervical polyp in a young adolescent with a previous rhabdomyosarcoma.Giant cervical polyps are rare entities, with only 8 reported cases in the international literature (medline 1966-2002). Of these cases, only one has been described in the pediatric population. There has been no report of a giant cervical polyp occurring in the older, although early, adolescent period. The discovery of a giant cervical polyp in a young adolescent is a gynecological oddity. The immense size of giant cervical polyps, together with their menacing appearance and unusual presentation, can simulate a malignant neoplasm. Care must be taken in their diagnosis and management so that the patient's fertility is not compromised. We report on a young adolescent girl with a previous history of a rhabdomyosarcoma (RMS), who presented with a giant cervical polyp protruding from the vaginal introitus. The literature on this entity is reviewed.- - - - - - - - - - ranking = 8keywords = giant (Clic here for more details about this article) |
7/44. Giant fibrovascular polyp of the esophagus. A lesion causing upper airway obstruction and syncope.Giant fibrovascular polyp of the esophagus is a rare but dramatic entity. These large polyps arise in the proximal esophagus and can cause airway obstruction secondary to mechanical pressure on the larynx, or they can present as a mass that is regurgitated into the oral cavity. We present a 66-year-old man who complained of nausea and vomiting that were associated with a fibrovascular polyp protruding into the mouth. He had also experienced several episodes of syncope resulting from intermittent airway obstruction. He underwent an open resection of an 11.8-cm fibrovascular polyp and an endoscopic resection of a second fibrovascular polyp 2 days later. Histopathologically, both masses were composed of a mixture of mature adipose tissue lobules and fibrovascular tissue, lined by reactive squamous epithelium. Despite their large size, giant fibrovascular polyps should be recognized radiologically and pathologically as benign lesions. However, they can result in significant morbidity.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/44. Giant fibrovascular polyp of the esophagus.The role of endoscopic ultrasound (EUS) in the diagnosis and management of a giant fibrovascular polyp of the esophagus in a 46-year-old woman is described here. The fibrovascular polyp was detected at esophagogastroduodenoscopy, and EUS demonstrated that it originated from the submucosa. EUS-guided fine-needle aspiration was performed, and cytological examination of the specimen revealed benign fibro-fatty elements. The lesion was resected via a transcervical esophagotomy. The literature on fibrovascular polyps is reviewed.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/44. Symptomatic gastric leiomyoma mimicking giant gastric polyp: endoscopic diagnosis and removal.Gastric leiomyoma is an uncommonly found benign submucosal neoplasm which may cause hemorrhage in rare cases. A 67-years-old patient was admitted to our attention due to two episodes of hematemesis and melena occurred in the previous two days. Esophagogastroduodenoscopy showed a giant semi-pedunculated gastric polyp (diameter of 4 centimeters) located at the distal body. A large ulcer with a clot was seen on the polyp. We treated endoscopically the giant polyp using the new two-steps-technique recently described by us for the treatment of the large pedunculated gastric and colorectal polyps, and the polypectomy was successfully performed without immediate or delayed complications. Histological evaluation of the transected polyp revealed morphology according to a gastric submucosal leiomyoma. Endoscopic control, performed one and four weeks and 12 months later, showed complete reepithelization of the gastric mucosa, without any sign of endoscopic, endosonographic and histological recurrence of the disease. This case report shows that our endoscopic approach may be successfully used also for giant semi-pedunculated gastric polyps.- - - - - - - - - - ranking = 7keywords = giant (Clic here for more details about this article) |
10/44. An unusual cause of complete distal ureteral obstruction: giant fibroepithelial polyp.Fibroepithelial polyp of the ureter is a rare benign neoplasm of mesodermal origin. It is an extremely rare cause of hydronephrosis in children. It usually causes partial ureteral obstruction without loss of renal function. The preferred treatment is endoscopic or surgical resection of the polyp with preservation of the renal unit. The authors present an adolescent patient with a nonfunctioning left hydronephrotic kidney caused by complete ureteral obstruction caused by a giant fibroepithelial polyp of the distal ureter. This is an extremely rare presentation and outcome of this benign ureteral neoplasm with resultant loss of renal unit.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
