1/57. 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.

2/57. Giant fibrovascular polyp of the esophagus.

    Giant fibrovascular polyps (FVP) are the most common intraluminal tumors of the esophagus. The case of a second, nonrecurrent FVP is presented. A thorough review of the literature was conducted to provide an informative discussion on this benign but potentially life-threatening neoplasm.

3/57. Inflammatory fibroid polyp of the esophagus.

    The case of a 76-year-old woman with a submucosal tumor of the esophagus, whose principal symptoms were dysphagia and epigastric/retrosternal pain, is reported here. endoscopy, barium swallow and a CAT scan all pointed to extramucosal localization. The lesion was located in the lower esophagus lying on the stomach fundus. An ulcer in the region of the cardia complicated the tumor. Two sets of conventional biopsies failed to detect malignancy, only inflammation and intestinal metaplasia were seen in the specimens of the mucosa surrounding the ulcer. The endoscopic ultrasonographic findings were an indistinct margin, hypoechogenicity, homogeneous appearance and location within the second and third echographic layer. The surgical resection of the tumor was complemented by an anterior partial fundoplication. The histologic study revealed an inflammatory fibroid polyp, which is a rare, benign, non-capsulated submucosal lesion composed mainly of loose connective tissue and vessels, with an eosinophilic inflammatory component. This lesion is seldom found in the esophagus.

4/57. Hamartomatous polyp of the esophagus.

    Hamartomatous polyp of the cervical esophagus in a 60-year-old man was treated by local resection, and the patient did well. The histopathologic findings showed a predominance of cartilaginous tissue, but the specimen also contained glandular structures and adipose tissue. The diagnosis was choristoma or hamartoma. review of the literature shows this to be the third case reported.

5/57. 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.

6/57. Fibrovascular polyp of the esophagus in infant.

    A five month female was referred complaining of intermittent vomiting with protrusion of a sausage-like mass through the oral cavity. Esophageal endoscopy and esophagogram revealed a mass in the upper esophagus, which was diagnosed as a fibrovascular polyp. Under general anesthesia, the mass was grasped through the oral cavity with a forcep and ligated and excised at the base, where a stump arose from the posterior wall of the cervical esophagus. The pathology was confirmed as a fibrovascular polyp, which is a rare benign esophageal lesion occurring mostly in adult males, and has not been reported in infancy.

7/57. Polypoid sarcomas of the esophagus. A rare but potentially curable neoplasm.

    Five patients with polypoid esophageal sarcoma are reported. All had dysphagia similar to that occurring in epithelial carcinoma of the esophagus. The clinical diagnosis of sarcoma was suspected when barium swallow showed a large polypoid lesion. biopsy was often inconclusive concerning the nature of the lesion except to identify it as a neoplastic process. In spite of their large size, the tumors remained superficial within the esophageal wall. Nodal or distant organ metastasis was absent in 4 of the 5 patients. The histology of these tumors suggests that so-called carcinosarcoma is an epithelial carcinoma of the esophagus with varying amounts of spindle cell features and should be considered separately from sarcoma arising from mesenchymal tissue. Unlike carcinoma, esophageal sarcoma has a favorable prognosis following radical resection, and recent advances in esophageal surgery have decreased the mortality and morbidity of esophagectomy.

8/57. Rare case of inflammatory fibrous polyp of the esophagus.

    Esophageal inflammatory fibrous polyps are extremely rare benign neoplasms. The manuscript illustrates a case of a man complaining of pyrosis and gastroesophageal reflux symptoms. Diagnostic work-up showed an expansive lesion of the distal esophagus simulating malignancy but with negative, repeated, multiple biopsies. The considerable size of the lesion, and the suspicion of a malignant tumor because of the presence of ulceration, indicated esophagectomy with extensive lymphadenectomy and intrathoracic esophagogastroplasty. The diagnosis of inflammatory polyp of the esophagus was achieved postoperatively. The Discussion deals with a review of the literature and considers the performed operation a good choice considering the hypothesis of a malign neoplastic evolution of this lesion.

9/57. Newly developed 3D endoscopic system: preliminary experience.

    Although there have been earlier reports on the use of three-dimensional endoscopic systems in the gastrointestinal tract, real-time three-dimensional imaging has not previously been described. This paper presents experience in three cases with a novel endoscopic system for three-dimensional observation in clinical situations. Case 1 was a hyperplastic gastric polyp, the shape of which was considerably enhanced in comparison with two-dimensional endoscopic viewing. Case 2 was an advanced esophageal cancer, in which the sense of depth was improved in the esophagus. Case 3 was a depressed early gastric cancer, the shape of which was also enhanced. Between July 2001 and March 2002, three experienced endoscopists also used this new system in a further 34 patients. A three-dimensional endoscopic environment was visible with the system in all patients, and all of the endoscopists were able to obtain visual information regarding spatial depth. This experience suggests that the three-dimensional video-endoscopic system used here can be of value in gastrointestinal endoscopy.

10/57. 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.
