1/52. 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.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/52. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/52. Metastasis of an esophageal carcinoma to a giant gastric ulcer.In patients with esophageal carcinoma it is considered that stomach metastasis is induced mainly via the lymphatic route rather than via the bloodstream route that is common in other types of distant organ metastasis. A 56 year-old patient is reported who underwent synchronous subtotal esophagectomy and total gastrectomy for a middle third esophageal carcinoma and a giant peptic ulcer within the gastric fundus. The final histopathologic examination revealed a squamous cell carcinoma of the esophagus with concomitant squamous tumor implantation within the gastric ulcer. The increased cell proliferation in the ulcer margin can serve as a "biological background or base" for implantation.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
4/52. Pleomorphic giant cell carcinoma of the esophagus with coexpression of cytokeratin and vimentin and neuroendocrine differentiation.A pleomorphic (giant cell) carcinoma of the esophagus is reported in a 52-year-old man who had dysphagia and weakness. The 8-cm-high vegetating tumor consisted of solid sheets of poorly cohesive epithelioid cells broken into clusters by strands of stroma. Numerous giant cells showing phagocytic phenomenon were present. Immunochemical analyses demonstrated the epithelial origin of the neoplasm, although most of the tumor cells strongly expressed vimentin. Numerous tumor cells expressed synaptophysin. Neurosecretory granules were detected in some tumor cells on electron microscopic examination. The patient died 4 months after he became symptomatic. As far as we can ascertain, this is the first case report describing a pleomorphic carcinoma arising in the esophagus. This poorly differentiated carcinoma might be of neuroendocrine differentiation. In the esophagus, pleomorphic carcinoma must be distinguished from polypoid tumors such as carcinosarcoma and malignant melanoma.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
5/52. Giant polypoid tumor of the esophagus.A patient with a giant polypoid tumor of the esophagus, measuring 22 cm in length is described in this report. The patient presented with cough attacks and respiratory distress. Diagnostic and therapeutic intervention required aggressive airway management, radiographic and endoscopic evaluation, and definitive surgical treatment. Benign esophageal tumors are rarely seen and originate from the upper third of esophagus, frequently close to the cricopharyngeus muscle. They may attain giant proportions. A variety of clinical presentations are described, the most serious being asphyxia secondary to laryngeal obstruction. We observed a giant esophageal tumor which was interpreted as angiofibromyolipoma that caused laryngeal obstruction. We present the clinical picture and histopathological findings of the tumor.- - - - - - - - - - ranking = 3keywords = giant (Clic here for more details about this article) |
6/52. 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.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/52. Recurrent esophageal fibrovascular polyps: case history and review of the literature.Fibrovascular esophageal polyps are rare benign tumors. They can grow to considerable length and cause symptoms such as dysphagia, retrosternal discomfort, vomiting, and even asphyxia. A barium contrast esophageal radiography will show a filling defect compatible with an esophageal mass. Surgical removal through cervical esophagotomy is the preferred treatment, and recurrences after surgery are rare. We describe a patient who developed three recurrent giant fibrovascular esophageal polyp within eight years. A review of the literature is given.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/52. Giant leiomyoma of the esophagus.leiomyoma is the most common benign tumour found in the esophagus but it is, however, a rare neoplasm; in fact of all esophageal tumours, benign tumours account for fewer than 10%, of which 4% are leiomyomas. Leiomyomas should be removed when diagnosed, even if asymptomatic, because malignancy cannot otherwise be excluded and symptoms are likely to develop if treatment is delayed or omitted. Enucleation of esophageal leiomyoma is a safe and effective procedure. We report a case of symptomatic giant anular leiomyoma of the distal esophagus, compressing the trachea and the descending aorta, resected after right thoracotomy.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/52. Giant esophageal leiomyoma with secondary megaesophagus.A 25-year-old woman presented with a giant leiomyoma in the lower third of the esophagus. She had no digestive symptoms, although there was a severe esophageal dilation. Such a megaesophagus secondary to a leiomyoma has not been described previously. Esophagogastric resection was performed, followed by an uneventful recovery period. The literature on esophageal leiomyoma is reviewed.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/52. Esophageal tuberculosis presenting with an appearance similar to that of carcinoma of the esophagus.A case of esophageal tuberculosis presenting with an appearance similar to that of esophageal cancer is reported. The patient was an 82-year-old man with progressive dysphagia. barium swallow and esophagoscopy revealed an elevated lesion with deep ulceration in the middle thoracic esophagus. Esophageal carcinoma, in particular, an undermining type of undifferentiated carcinoma, was suspected fluoroscopically and endoscopically. Histological examination of biopsy specimens revealed no malignancy, but there were epithelioid granulomas and a few Langhans' type multinucleated giant cells. Endoscopic ultrasonography clearly demonstrated an extramural lesion with calcification and direct infiltration of enlarged subcarinal lymph nodes into the esophageal wall. Ultrasonographic and histological findings indicated the possibility of esophageal tuberculosis. Although no bacteriological evidence was obtained, a therapeutic trial for tuberculosis, using antituberculous drugs, was started. After 2 weeks, the enlarged subcarinal lymph nodes were markedly reduced in size. The patient's symptoms improved gradually and had disappeared 8 weeks after he started treatment, when tubercle bacilli were isolated from sputum. A connection between the esophageal wall and its adjacent structures was clearly demonstrated by endoscopic ultrasonography. For patients with findings indicative of esophageal tuberculosis on endoscopic ultrasonography, a therapeutic trial for tuberculosis should be considered, even if polymerase chain reaction assay or culture is negative.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
