1/293. Pseudocapsulorrhexis in a patient with iridocorneal endothelial syndrome.We describe a patient with Chandler's syndrome variant of the iridocorneal endothelial syndrome in whom ectopic Descemet's membrane was found intraoperatively on the anterior surface of the lens. Initially, the membrane was confused with the anterior lens capsule during extracapsular cataract extraction, leading to the performance of a pseudocapsulorrhexis. Electron microscopy disclosed that the epilenticular membrane was composed of multiple layers of abnormal basement membrane consistent with the iridocorneal endothelial syndrome.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
2/293. Nasal gliomas: main features, management and report of five cases.Nasal gliomas are neurologic malformations that should be considered in the presence of a congenital nasal mass. Appropriate pre-operative examination must be performed to identify a possible connection with CNS, which is present in 15-20% of the cases. This examination should determine whether initial craniotomy is necessary. Here, we report five cases and review the main characteristics and management of this pathology.- - - - - - - - - - ranking = 3.1383879019347keywords = propria (Clic here for more details about this article) |
3/293. electrocoagulation biopsy of aberrant pancreas of the stomach. A case of aberrant gastric pancreas.Histopathological diagnosis of submucosal tumors of the stomach has been difficult by conventional examination, e.g. roentgenography, gastroscopy and/or routine biopsy procedure. When endoscopic diagnosis of submucosal tumor is made, surgery is generally performed for tissue biopsy. We have been attempting to avoid such exploratory laparotomy to determine the histologic nature of small asymptomatic submucosal tumors of the stomach by a technic of endoscopic biopsy followed by electrocoagulation. With such a procedure, we have been able to diagnose a case of aberrant pancreas of the stomach. Our experience suggests that this technic is a safe and useful diagnostic tool.- - - - - - - - - - ranking = 526.18257622983keywords = mucosa (Clic here for more details about this article) |
4/293. Symptomatic heterotopic gastric mucosa in the upper oesophagus.The presence of heterotopic gastric mucosa in the upper oesophagus has been reported to occur in up to 10 per cent of individuals but it is usually asymptomatic. We present two patients with symptomatic oesophageal heterotopic gastric mucosa and discuss the aetiology, pathogenesis, and management of the condition.- - - - - - - - - - ranking = 1052.3651524597keywords = mucosa (Clic here for more details about this article) |
5/293. Laparoscopic resection for ectopic gastric mucosa of the duodenum: report of a case.We report herein the case of a 53-year-old man in whom ectopic gastric mucosa was successfully resected laparoscopically. radiography and endoscopy showed a well-demarcated and sessile polypoid lesion measuring 2.0 cm in diameter in the second part of the duodenum. Under the diagnosis of a submucosal tumor of the duodenum, a wedge resection of the duodenum was performed laparoscopically. Subsequent histological examination revealed that the tumor was ectopic gastric mucosa of the duodenum.- - - - - - - - - - ranking = 1227.7593445363keywords = mucosa (Clic here for more details about this article) |
6/293. A case of aberrant pancreatic cancer in the jejunum.We report a case of aberrant pancreatic cancer of the jejunum in a 63 year-old man. The patient was admitted to our hospital with epigastric discomfort and vomiting due to obstruction of the jejunum. laparotomy revealed a submucosal tumor on the jejunum with multiple liver metastases. Histological examination showed the tumor to be a well differentiated tubular adenocarcinoma originating from aberrant pancreatic tissues lacking islets. Only 1 case of aberrant pancreatic cancer in the jejunum has been previously reported in the literature.- - - - - - - - - - ranking = 175.39419207661keywords = mucosa (Clic here for more details about this article) |
7/293. Heterotopic pancreas as lead point in intussusception: new variant of vitellointestinal tract malformation.Two cases of intussusception are reported with heterotopic pancreatic tissue attached to and draining into the ileum. The first patient, a boy aged 16 months, presented with ileoileal intussusception. The diagnosis was confirmed on ultrasound scan. laparotomy and resection were performed. A 12-mm nodule of heterotopic pancreatic tissue was identified in the ileal serosa at the apex of the intussusceptum, fully formed with acinar tissue, islets, and draining duct. The second patient, also a boy aged 16 months, presented with obstructed ileocolic intussusception in which the lead point at surgery resembled a Meckel's diverticulum. Histopathology revealed a similar 10-mm nodule of fully formed pancreatic tissue in the ileal serosal tissues, with some acinar tissue extending through the wall of the intestine alongside ductal structures. In both cases there was ectopic gastric mucosa either in the distal part of the draining duct or in the small intestine itself at the opening. Heterotopic pancreas is a rare cause of intussusception. We propose that this lesion is of vitellointestinal tract origin, conceptually similar to a Meckel's diverticulum but without a diverticulum as such. Heterotopic pancreatic tissue occurring alone is more common in the proximal small intestine, duodenum, and stomach than in the ileum, and it is often asymptomatic.- - - - - - - - - - ranking = 175.39419207661keywords = mucosa (Clic here for more details about this article) |
8/293. lingual thyroid gland: clinical evaluation and comprehensive management.Although lingual thyroid gland is the most common benign mass found at the junction of the anterior two-thirds and the posterior one-third of the tongue, it is still a rare clinical entity. This developmental anomaly is the result of an arrested descent of the gland anlage early in the course of embryogenesis. patients may have symptoms of dysphagia due to obstruction or even hemorrhage. These symptoms can occur at any time from infancy through adulthood. The clinical findings, laboratory tests, and radiographic imaging studies employed in confirming the diagnosis and in planning appropriate treatment have been evaluated. The primary therapeutic goal is to restore thyroid function. We describe a case of lingual thyroid gland and summarize the current management principles for this condition.- - - - - - - - - - ranking = 3.1383879019347keywords = propria (Clic here for more details about this article) |
9/293. Heterotopic sebaceous glands in the esophagus: histopathological and immunohistochemical study of a resected esophagus.A resected esophagus with numerous heterotopic sebaceous glands was examined in an attempt to determine whether esophageal heterotopic sebaceous glands are the result of a metaplastic process or a congenital anomaly. The present case concerns a 79-year-old Japanese man with numerous esophageal heterotopic sebaceous glands accompanied by superficial esophageal cancer. The resected esophagus possessed numerous heterotopic sebaceous glands, which could be seen clearly as slightly elevated, yellowish lesions. Histological examination of these glands, all of which were located in the lamina propria, revealed lobules of cells that showed characteristic sebaceous differentiation. Bulbous nests of proliferating basal cells showing sebaceous differentiation were occasionally observed in the esophageal epithelium. Of the antibodies against six different keratins used, only anti-keratin 14 labeled both the heterotopic sebaceous glands and the bulbous nests. Acquired metaplastic change of the esophageal epithelium is probably the pathogenetic mechanism involved in these unusual lesions.- - - - - - - - - - ranking = 3.1383879019347keywords = propria (Clic here for more details about this article) |
10/293. Tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.Ectopic thyroid tissue within the submucosa of the trachea is a rare cause of upper airway obstruction. Primary neoplasms arising from such thyroid nests are rare.
