2/487. 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.- - - - - - - - - - ranking = 2.7807708592014keywords = neoplasm (Clic here for more details about this article) |
3/487. diagnosis and physiopathology of laryngeal deposits in autoimmune disease.We report the clinical features and pathology of a previously unreported form of vocal fold disease seen in 4 patients, 3 of whom were diagnosed as autoimmune disease. The characteristic features of these lesions were found as bilateral transverse lesions in the mid portion of the vocal folds. The patients had dysphonia and diplophonia. Stroboscopic examinations showed 180-degree phase shifts between the anterior and posterior portion of the vocal folds. Case 1 had systemic lupus erythematosus, case 2 had Hashimoto's thyroiditis, and case 3 had progressive systemic sclerosis. Prior to the onset of hoarseness, autoimmune antibody titers were increased. These cases need differential diagnosis from vocal fold nodules and cysts. Two cases were recurrent after endoscopic surgery, 1 recurring 3 times. Glucocorticoid was effective in preventing the recurrence in the early phase. recurrence may have occurred because the surgical strategy was the same as that used for vocal fold nodules or cysts.- - - - - - - - - - ranking = 0.16666666666667keywords = ear (Clic here for more details about this article) |
4/487. tamoxifen-associated polyps (basalomas) arising in multiple endometriotic foci: A case report and review of the literature.We present a case of a 62-year-old G0P0 Caucasian woman who developed endometrial adenocarcinoma, FIGO grade 2, endometrioid type, after receiving tamoxifen for 2 years following a diagnosis of invasive carcinoma and ductal carcinoma in situ of the breast. An incidental finding in the hysterectomy specimen was numerous endometriotic foci involving the submucosa, subserosa, and serosa of the cervix; lower uterine segment serosa; and bilateral ovaries. Polypoid structures, similar to the endometrial polyps occurring in tamoxifen-treated patients, were observed to arise from endometriotic foci in the serosa of the cervix and bilateral ovaries. We have found only one similar report in the literature. Since these structures do not fit the definition of "polyp," we suggest "basaloma" as an alternative. We also review all cases of tamoxifen-associated endometriosis reported in the world literature and cases of polypoid endometriosis occurring in non-tamoxifen-treated patients. Of 12 reported cases of tamoxifen-associated endometriosis, 4 occurred in premenopausal women, 1 in a perimenopausal women, and 7 in postmenopausal women, of whom none had a known history of endometriosis. The endometriotic foci gave rise to a spectrum of lesions which included epithelial metaplasias, simple and complex hyperplasias, polypoid lesions, and 2 cases of endometrioid carcinomas.- - - - - - - - - - ranking = 0.33333333333333keywords = ear (Clic here for more details about this article) |
5/487. motilin-producing liver and bone metastases evidenced 14 years after resection of a rectal polyp.A 62-year-old man with a history of a resected rectal polyp was diagnosed 14 years later with right liver and multiple bone metastases. The liver biopsy showed a malignant epithelial tumor that was positive for neuron-specific enolase immunostaining and negative for chromogranin. Electron microscopy was characteristic of that for an endocrine tumor. Most circulating hormonal peptide levels were within normal ranges and only motilin level was elevated. On the right hepatectomy, the three large metastases had a histologic picture suggestive of an endocrine tumor. immunohistochemistry revealed in some areas numerous tumor cells expressing motilin, and a few cells were strongly positive for pancreatic polypeptide and somatostatin. The retrospective analysis of the rectal polyp showed a similar histology and immunohistochemical profile, indicating that this lesion was the primary tumor. motilin-positive cells from one of the hepatic lesions were identified on semithin sections and further processed for electron microscopy. Neurosecretory granules were numerous in all cells. Immunoelectron localization enabled us to characterize the motilin-containing neurosecretory granules, which had a mean diameter of 168.3x38.1 nm. Although not all tumor cells were motilin-positive, a diagnosis of motilinoma for the rectal polyp and its hepatic and bone metastases was proposed.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
6/487. Report of a rare case of vocal fold carcinoma that was obscured by a prominent vocal fold polyp.We report the case of a 56-year-old man who was evaluated for hoarseness. Telescopic and fiberoptic examination revealed a huge, pedunculated polyp that obscured the vocal folds. Upon further examination, microlaryngoscopy revealed a coexisting superficial irregular lesion on the upper surface of the left vocal fold, which was identified as a microinvasive carcinoma. This unusual presentation emphasizes the importance of a microlaryngoscopic examination.- - - - - - - - - - ranking = 0.16666666666667keywords = ear (Clic here for more details about this article) |
7/487. Imaging of fibrosis of the oral mucosa by 20 MHz sonography.OBJECTIVES: To compare the ultrasonographic (US) appearances of the oral mucosa in health with patients with systemic sclerosis (SSc). methods: An innovative 20 MHz US scanner was used to examine the lips, cheeks and oral vestibule of ten healthy persons and ten patients with SSc. The clinical, US and histopathological features of one patient with a fibro-epithelial polyp of the buccal mucosa are reported in detail. RESULTS: Two patients with SSc displayed increased echogenicity due to fibrotic deposits. A similar echo pattern was seen in the case of the histopathologically verified fibro-epithelial polyp of the buccal mucosa. CONCLUSION: 20 MHz sonography may be suitable as a non-invasive tool for evaluation of fibrosis of the oral mucosa.- - - - - - - - - - ranking = 0.16666666666667keywords = ear (Clic here for more details about this article) |
8/487. Sulfatide cholecystosis.Polypoid masses metachromatic sulfatides have been found at autopsy in the gallbladder of patients with metachromatic leucodystrophy. In a 10-year-old girl with this disease oral cholecystrography demonstrated a filling defect, which was felt to represent a polyp. In the proper clinical setting, sulfatide cholecystosis should be considered in the differential diagnosis of polypoid lesions of the gallbladder.- - - - - - - - - - ranking = 0.16666666666667keywords = ear (Clic here for more details about this article) |
9/487. Gastric hyperplastic polyp occurring at the resection site of gastric adenoma.Endoscopic mucosal resection was carried out in a 70-year-old man with a gastric adenoma. endoscopy 1 year later revealed a subpedunculated polyp about 1 cm in diameter at the resection site. Pathological examination of the resected specimen showed hyperplasia of the regenerative epithelium. The mechanism of occurrence of hyperplastic polyp at the resection site is discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = ear (Clic here for more details about this article) |
