1/247. 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.

2/247. Squamous cell papillomatosis of esophagus following placement of a self-expanding metal stent.

    The esophageal self-expanding metal stent has gained widespread acceptance for the management of tracheoesophageal fistulas and the palliative management of malignant esophageal strictures. The complications associated with its use can be classified as either immediate or delayed. The most frequent delayed complications include tumor ingrowth, stent migration, reflux of gastric contents, bleeding, and perforation. This case report illustrates an otherwise unrecognized delayed complication of a self-expanding metal stent. Near complete ingrowth of the stent by squamous mucosal hyperplasia occurred within six weeks of the metal stent's placement. This finding supports the hypothesis that mucosal injury and regeneration underlies the etiology of esophageal squamous cell papilloma formation.

3/247. 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.

4/247. Metachronous pulmonary and oesophageal neoplasia.

    Primary carcinomas of the lung and oesophagus are common, surgical resection offers the only hope of long-term survival with both conditions. We present the unusual case of a patient who underwent transhiatal oesophagectomy for an adenocarcinoma carcinoma of the oesophagus, 5 years after left pneumonectomy for small cell carcinoma of the lung.

5/247. Second primary Barrett's adenocarcinoma after 19 years.

    Because long survival after resection of esophageal carcinoma is uncommon, second esophageal cancers are rare. We report the case of a patient in whom adenocarcinoma developed within residual Barrett's esophagus 19 years after esophagectomy for stage IIb Barrett's adenocarcinoma. Implications relative to the type of operation and adequacy of resection are discussed. Long-term survival after Barrett's adenocarcinoma may occur more often if surveillance protocols achieve their aim. Questions concerning the management of such patients are identified.

6/247. Anaplastic and sarcomatoid carcinoma of the small intestine: an unusual tumor.

    Primary malignant tumors of the small intestine are rare, and sarcomatoid carcinomas have rarely been reported at this site. Anaplastic and sarcomatoid carcinomas are well described in the upper aerodigestive tract, particularly in the esophagus and the larynx. The authors report a case of anaplastic and sarcomatoid carcinoma of the ileum presenting as gastrointestinal bleeding. Their patient and the literature suggest that these tumors are much more aggressive than other small intestinal tumors. The importance of a systematic diagnostic approach in diagnosing these tumors is also discussed.

7/247. Clonal analysis of a case of multifocal oesophageal (Barrett's) adenocarcinoma by comparative genomic hybridization.

    Oesophageal adenocarcinomas arising in Barrett's epithelium occasionally present as multiple lesions. This could be due to either a multifocal presentation of the same tumour, or different neoplasms arising simultaneously in a dysplastic Barrett's oesophagus ('field cancerization'). This is a report of the genetic analysis of multiple neoplastic sites in a Barrett's oesophagus with an extensive area of dysplasia. In addition, the dysplastic Barrett's epithelium was evaluated. For the genetic screening, comparative genomic hybridization (CGH) allowed evaluation of the whole genome of each specimen. Five cancerous regions were selected and subsequently dissected from paraffin-embedded tissue blocks. The use of archival materials enabled a targeted collection of representative tumour locations. Multiple genetic aberrations were detected by CGH in all cancer sites. Losses on 3p, 4, 7q, 18q, and Y, as well as gains on 8q, 9q, 12p, 13q, 17q, 20p and X, were found in each specimen. In four out of the five lesions, simultaneous losses on 9p, 15q, and 16q, with concomitant gains on 5p, 7q, and 10p, were disclosed by CGH. Adjacent high-grade dysplastic Barrett's mucosa shared the losses on 3p, 4, 7q, 9p, 18, and Y, as well as the gains on 5p, 7q, 13q, 17q, and X, thereby confirming its precursor status. Within this single and rare case of multifocal Barrett's adenocarcinoma, a monoclonal genotype was present. This must have been caused by an extensive outgrowth of a single tumour.

8/247. Pleural incarceration of the gastric graft after trans-hiatal esophagectomy.

    We report on a 73-year-old man who underwent a transhiatal esophagectomy for a T2N1M0 adenocarcinoma of the distal esophagus and developed an incarcerated herniation of the gastric graft through a defect in the right mediastinal pleura. The patient experienced delayed gastric emptying postoperatively, which was initially suggested by barium swallow. The gastric herniation was unidentified by early postoperative swallowing studies and endoscopies. After diagnosis by a later computed tomographic scan and barium study, the herniation was reduced by incising the mediastinal pleura from the diaphragm to the apex of the chest and by plication of the stomach longitudinally in order to reduce its intrathoracic diameter.

9/247. Local treatment of early cancer in short Barrett's esophagus by means of argon plasma coagulation: initial experience.

    In recent years endoscopically controlled local therapeutic methods, such as photodynamic therapy, mucosectomy, or laser therapy, have been used with a curative aim for the destruction of early esophageal or gastric cancers. We report on our experience of treating histologically proven mucosal cancer in Barrett's esophagus with argon plasma coagulation (APC), in three patients. All the mucosal esophageal cancers, with a mean diameter of 4 mm, were successfully destroyed after one or two treatment sessions. Additionally, in two of the three patients the specialized columnar epithelium was replaced by normal squamous cell epithelium when APC treatment was combined with omeprazole. In the third patient with Barrett's esophagus, a partial squamous cell re-epithelialization was induced. No method-related mortality and morbidity were observed. During the mean follow-up of 24.3 /- 1.1 months (range 23-25 months) one tumor recurrence developed which was successfully treated with photodynamic therapy. In patients with small early Barrett's carcinoma APC might offer an effective, minimally invasive alternative to mucosectomy or photodynamic therapy, as the treatment procedure is less cumbersome and the equipment less expensive.

10/247. Clinicopathological and immunohistochemical study of cancer arising from Barrett's esophagus.

    In japan, Barrett's esophageal cancer is a very rare disease. We examined clinicopathologically and immunohistologically 4 patients with Barrett's esophageal cancer who underwent surgical resection in our department. Barrett's esophageal mucosa was classified into 3 types for detailed observation. Specialized columnar epithelium (SCE) remained on the orifice side of carcinoma, and progression to adenocarcinoma was observed in some dysplastic glands. positive findings were detected on p53 immunohistochemical staining, and the ki-67 labeling index was higher than other types. SCE-type Barrett's esophagus may be a precancerous lesion arising prior to the development of adenocarcinoma.
