1/1006. Hodgkin's disease of the esophagus: report of a case.Most esophageal malignancies are either squamous carcinomas or adenocarcinomas arising in the background of Barrett's esophagus. We describe a case of an 85-yr-old woman in whom the diagnosis of esophageal malignancy was difficult to confirm despite its endoscopic appearance and previous biopsies. This case illustrates the difficulty in diagnosing Hodgkin's disease of the esophagus. Despite the rarity of this entity, if clinically indicated by symptoms, large, deep biopsies by rigid esophagoscopy should be considered.- - - - - - - - - - ranking = 1keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
2/1006. Metastatic esophageal carcinoma to the orbit.PURPOSE: To report a case of esophageal adenocarcinoma and areas of gastric differentiation in the esophagus (barrett esophagus) metastatic to the orbit. methods: A 47-year-old man with a history of esophageal carcinoma developed turgescence around his left eye. He underwent a biopsy and histologic examination of a left orbital mass. RESULTS: Histopathology of the orbital tumor was consistent with metastatic adenocarcinoma from the esophagus. CONCLUSIONS: This metastatic adenocarcinoma to the orbit likely arose in barrett esophagus.- - - - - - - - - - ranking = 3.8671550283742keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
3/1006. Pedunculated esophageal leiomyosarcoma: a case report.We report a case of esophageal leiomyosarcoma that possibly arose from the muscularis mucosae, thereby showing a particularly unusual appearance. A large polypoid intraluminal lesion in the distal esophagus was found on an endoscopic examination of a 68-year-old man with a 3-month history of dysphagia. Although the histological examination of biopsy specimens clearly revealed leiomyosarcoma, the absence of an exophytic component on computed tomography (CT) scan caused us to suspect that the tumor was carcinosarcoma. The tumor was resected by a subtotal esophagectomy. Microscopic evaluation revealed no involvement in the layer of the muscularis propria and no component of carcinoma. Clinical features of the pedunculated esophageal leiomyosarcoma shown in this case and three additional cases previously reported in the literature are reviewed.- - - - - - - - - - ranking = 0.43357751418709keywords = carcinoma (Clic here for more details about this article) |
4/1006. p53 gene mutation in 150 dissected lymph nodes in a patient with esophageal cancer.For thoracic esophageal cancer, we perform extended three field lymph node dissection, and have achieved nearly 50% of overall 5-year survival. However, patients sometimes develop lymph node recurrences in spite of having no lymph node metastases found by conventional histopathologic examination. In a patient with esophageal squamous cell carcinoma, we sequenced all the p53 cDNA translated regions (exon 2-10) of primary carcinoma, and confirmed one p53 nonsense mutation in exon 10. Then we extracted genomic dna from 150 surgically dissected lymph nodes from that patient, and performed polymerase chain reaction analysis (PCR-RFLP) to detect the same p53 mutation in the lymph nodes. PCR-RFLP analysis showed the same p53 mutation in six lymph nodes. One node was located along the right recurrent laryngeal nerve, where no positive nodes was identified by conventional histopathologic examination. The p53 mutational diagnosis of metastatic cancer may be useful in detecting minimal residual disease.- - - - - - - - - - ranking = 0.86715502837418keywords = carcinoma (Clic here for more details about this article) |
5/1006. To B or not to B: is tylosis B truly benign? Two North American genealogies.Tylosis is a rare, autosomal dominant syndrome presenting with hyperkeratosis of the palms and soles of the feet. Two types have been identified. Late onset tylosis (type A) is reported to be associated with a high incidence of esophageal carcinoma, whereas early onset tylosis (type B) appears to be a benign disorder. This distinction has significant implications for surveillance and prognosis. We report two families exhibiting early onset type B tylosis, spanning five and seven generations, respectively, and believe these to be the first two extensive genealogies of tylosis type B reported in north america. They serve to verify the features of type B tylosis and its benign prognosis. The world literature is reviewed and clinical relevance is discussed. Recommendations for follow-up of afflicted individuals are proposed.- - - - - - - - - - ranking = 0.43357751418709keywords = carcinoma (Clic here for more details about this article) |
6/1006. tracheoesophageal fistula caused by a self-expanding esophageal stent.A patient is presented who had previously undergone an esophagectomy for an adenocarcinoma of distal esophagus. He experienced repeated strictures at the esophagogastric anastomosis at 22 cm. After multiple dilatations, a self-expanding metal stent was placed. Four months later the upper edge of the stent eroded through the esophagus into the trachea, forming a tracheoesophageal fistula. Muscle flap repair was successful.- - - - - - - - - - ranking = 0.56642248581291keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
7/1006. radiation-induced esophageal carcinoma 30 years after mediastinal irradiation: case report and review of the literature.A 54-year-old man who had been irradiated in 1964 for cervical involvement by Hodgkin's disease was admitted in December 1994 to our clinic with strong complaints of dysphagia. The reason was a moderately differentiated squamous cell carcinoma of the proximal esophagus in the previously irradiated region. The patient had no risk factors (abuse of nicotine or alcohol) for the developement of esophageal carcinoma. A reirradiation was performed, but the disease progressed locally and two weeks after the beginning of the therapy the patient developed two tracheoesophagocutaneous fistulae. The radiation therapy was discontinued and the tumor stenosis was bridged by a tube closing the fistulae. A retrospective dose analysis to evaluate the applied doses will be performed. Furthermore, an overview of 66 cases of the literature with radiation-induced esophageal carcinoma analysed concerning applied dose and latent interval will be given. In conclusion the reported case fits the criteria for radiation-induced malignancies (Chudecki Br J Radiol 1972;45:303-4) known from literature: (1) a history of previous irradiation, (2) a cancer occurring within the irradiated area, (3) gross tissue damage due to an excessive dose of radiation, and (4) a long latent interval between irradiation and development of cancer. Esophageal carcinomas belong to the rare secondary malignancies after the therapeutic use of ionizing radiation. Nevertheless in patients with dysphagia they should be suspected as a differential diagnosis even many years after mediastinal irradiation. The treatment of these tumors is very difficult and is associated with a poor prognosis.- - - - - - - - - - ranking = 3.4686201134967keywords = carcinoma (Clic here for more details about this article) |
8/1006. Massive pleural effusion and ascites resulting from esophagectomy with extensive lymphadenectomy for cancer of the abdominal esophagus.chylothorax is an uncommon but well recognized complication of esophagectomy. We present the case of a 57 year-old man with squamous cell carcinoma of the abdominal esophagus who underwent subtotal esophagectomy by right thoracotomy. Post-operatively, the volume of pleural effusion from the right chest was increased (1600-2000 ml/day). The effusion was straw colored, not changing to milky after meals. The characteristics and composition of the pleural fluid were similar to those of chyle. We therefore treated this patient using methods for treatment of chylothorax, conservatively, by administration of OK-432 and minocycline/hydrochloride into the pleural cavity from the chest tube with success. We discuss the pathophysiology of this unusual condition and its treatment.- - - - - - - - - - ranking = 0.43357751418709keywords = carcinoma (Clic here for more details about this article) |
9/1006. Esophageal adenocarcinoma that probably originated in the esophageal gland duct: a case report.A case of primary esophageal adenocarcinoma in a 64-year-old man is reported. An ulcerating tumor was located in the middle intrathoracic esophagus. Histopathological examination revealed a moderately differentiated adenocarcinoma, which had invaded down to the adventitia. The cancerous tubuli were lined by flattened cuboidal cells with eosinophilic cytoplasm, which were analogous with the esophageal gland ducts and syringoma of the skin. The carcinoma was spread widely in the lamina propria mucosae without intraepithelial neoplastic elements. An immunohistochemical profile of individual cytokeratins and other epithelial markers in the carcinoma was similar to that of the esophageal gland ducts. Barrett's metaplastic epithelium or ectopic gastric mucosa was not found around the tumor. It is strongly suggested that this unique carcinoma is derived from the esophageal gland ducts.- - - - - - - - - - ranking = 4.6992674574387keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
10/1006. Esophageal mucoepidermoid carcinoma containing signet-ring cells: three case reports and a literature review.We report 3 cases of esophageal signet-ring cell carcinoma which were found in a set of 505 resected esophageal tumors. The incidence of esophageal signet-ring cell carcinoma was 0.6%. All of the signet-ring cell carcinomas were histologically mixed with squamous cell carcinoma (mucoepidermoid carcinoma). The signet-ring cells had intracellular mucin, which was positive for both periodic acid-Schiff (PAS) and alcian blue at pH 2.5. At the time of presentation, extensive extraesophageal tumor spread and local extension were found in all cases. All of the patients died within 2 years after the esophagectomy irrespective of whether they received chemotherapy or radiotherapy. Our results, and those previously reported, suggest that most esophageal carcinomas containing signet-ring cell carcinoma are aggressive neoplasms associated with a poor prognosis after esophagectomy.- - - - - - - - - - ranking = 4.769352656058keywords = carcinoma (Clic here for more details about this article) |
