1/179. Bilateral renal masses after local bacillus Calmette-Guerin therapy for postcystectomy ureteral cancer.bacillus Calmette-Guerin was administered through the ileal conduit of a 63-year-old man with upper tract recurrence of transitional cell carcinoma. Subsequent computed tomography showed bilateral renal masses, which were granulomatous at pathologic examination. The bacilli likely reached the kidneys via proven ileoureteral reflux. patients with reflux may benefit from antituberculous prophylaxis.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/179. 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 = 1.8160239914442keywords = cancer, neoplasm (Clic here for more details about this article) |
3/179. Pulmonary small cell carcinoma associated with sarcoid reactions: report of a case.A 45-year-old male was admitted to our hospital for investigation of a nodular shadow in segment 5 of the right lung on a chest computed tomogram. A right middle lobectomy with mediastinal lymph node dissection was performed under a diagnosis of lung cancer, and histologic examination confirmed small cell carcinoma. There were sarcoid reactions in the resected lymph nodes and the lung parenchyma, but no signs of systemic sarcoidosis were evident. Sarcoid reactions are rarely observed in the regional lymph nodes draining malignant tumors. Moreover, while they are most common in squamous cell carcinoma of the lung, they extremely rare in small cell carcinoma. To our knowledge, this is only the third report of this unusual entity in the English and Japanese literature.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
4/179. Peritoneal sarcoidosis: case report and review of the literature.OBJECTIVES: This study was performed to report a patient with peritoneal sarcoidosis and review the literature for similar cases. methods: We described the clinical presentation, course, and outcome of the patient, and reviewed the medical literature from 1966 till 1997 using medline and the key words sarcoidosis, scar, and peritoneum. RESULTS: Our patient presented with a rapidly growing tumor-like mass at the site of an old appendectomy scar. laparoscopy showed a large peritoneal mass and multiple small peritoneal nodules that were found to be noncaseating granulomas by pathology. The medline search uncovered only 16 cases of peritoneal sarcoidosis, most of which presented with ascites. CONCLUSION: This case illustrates the need to consider sarcoidosis, in addition to infections and neoplasms, in the differential diagnosis of peritoneal nodules and exudative ascites.- - - - - - - - - - ranking = 0.0660239914442keywords = neoplasm (Clic here for more details about this article) |
5/179. lymphomatoid granulomatosis in a child with acute lymphatic leukemia in remission.lymphomatoid granulomatosis, a tumor-like process of unknown etiology, produced progressively destructive disease of the larynx, trachea and bronchi in an eight-year-old girl with acute lymphoblastic leukemia of five years duration. The leukemia had been in remission for 4 1/2 years at the clinical onset of the lymphomatoid granulomatosis. Whether this occurrence suggests that lymphomatoid granulomatosis is a type of neoplasm, or is associated with immunologic depression, cannot be stated. Fortunately rare, and of poor prognosis, the disorder may become more frequent with improved survival rate of patients with leukemia and other neoplasms.- - - - - - - - - - ranking = 0.1320479828884keywords = neoplasm (Clic here for more details about this article) |
6/179. Gastric cancer with sarcoid reactions in the regional lymph nodes, the stomach wall, and the splenic parenchyma: report of a case.A 66-year-old man was referred to our institute for investigation of heartburn and epigastralgia. Endoscopic examination demonstrated a type 4' gastric cancer which occupied the whole stomach. At laparotomy, multiple small nodules were found in the spleen which were diagnosed as metastases of the gastric cancer. Thus, total gastrectomy with distal pancreatectomy, splenectomy, cholecystectomy, and left adrenalectomy, combined with D4 lymph node dissection, was performed. Microscopic examination of the tumor revealed tubular and mucinous adenocarcinoma which invaded the muscularis propria. Sarcoid reactions were observed in the submucosa adjacent to the carcinoma tissue. Only one lymph node from station no. 8a demonstrated tumor metastasis, while those from station nos. 1, 2, 7, 8, 9, 10, 11, 13, and 16 revealed sarcoid reactions without tumor metastases. Subsequently, the multiple small nodules that had been presumed to be splenic metastases at laparotomy were found to be sarcoid reactions similar to those seen in the submucosa and regional lymph nodes. Since no skin or ocular lesions indicative of systemic sarcoidosis were seen in this patient, a diagnosis of advanced gastric cancer associated with sarcoid reactions was established. To our knowledge, there have been no previous reports regarding an association between sarcoid reactions in the spleen and gastric cancer.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
7/179. Endoscopic sonography in the diagnosis of xanthogranulomatous cholecystitis.Xanthogranulomatous cholecystitis (XGC) is an unusual inflammatory disease of the gallbladder that may simulate gallbladder cancer. We report the findings with conventional sonography, endoscopic sonography (EUS), and CT in 3 cases of XGC. EUS could visualize hyperechoic nodules in the gallbladder wall, probably representing xanthogranulomas, but loss of the multilayered structure of the gallbladder wall and infiltration into adjacent organs make differentiating XGC from gallbladder cancer difficult with EUS alone.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
8/179. myiasis secondary to Sermatobia hominis (human botfly) presenting as a long-standing breast mass.A case of a 54-year-old woman who presented with a breast mass is reported. Histologically, a chronic granulomatous inflammatory response was observed. The response was associated with an organism diagnosed as a fly larva, Dermatobia hominis (human botfly). The incidence of myiasis, infestation by fly larvae, presenting as a long-standing breast mass and mimicking a neoplasm is extremely rare, especially in the united states.- - - - - - - - - - ranking = 0.0660239914442keywords = neoplasm (Clic here for more details about this article) |
9/179. A patient with diabetes insipidus and periorbital swellings; erdheim-chester disease.erdheim-chester disease is a rare multisystem disease in which a progressive xanthogranulomatous infiltration of several tissues can be seen. We describe a woman, known to have diabetes insipidus for ten years, with periorbital, retroperitoneal, mediastinal, axillar and inguinal involvement. On histological examination a granulomatous infiltration of fatty tissue and striated muscle was seen, consisting of Touton giant cells, histiocytes with foamy cytoplasm and lymphocytes. Immunohistochemical staining with CD-1a and S-100 was negative and on electron microscopy no Langerhans granules were seen. These findings led to the diagnosis of erdheim-chester disease. She had a good response on steroids. Because of some similar clinical features of Langerhans cell histiocytosis and erdheim-chester disease, a histiocyte disorder seems the most probable cause.- - - - - - - - - - ranking = 0.076295546369061keywords = muscle (Clic here for more details about this article) |
10/179. Fibro-osseous lesions of the central nervous system: report of four cases and literature review.Fibro-osseous lesions, also reported as calcifying pseudoneoplasms of the neural axis, are uncommon lesions of the CNS. We report four additional cases: two extraaxial and two intraaxial, in patients ages 33, 47, 49, and 59 years at presentation. Fibro-osseous lesions involving the CNS demonstrate variable proportions of fibrous stroma, bone, palisading spindle to epithelioid to multinucleated cells in association with a highly distinctive, perhaps pathognomonic, chondromyxoid-like matrix often distributed in a nodular pattern. This histopathologically distinctive lesion can be seen in many regions of the neuraxis, often with a dural association, and most commonly along the vertebral column. It appears to be a slow-growing lesion and, with wide excision, the prognosis is excellent. The etiology remains unclear, but the preponderance of data favors a reactive rather than neoplastic process. If this putative pseudotumor is not recognized histopathologically, a neoplastic or infectious differential might result in inappropriate investigations and potentially harmful therapies.- - - - - - - - - - ranking = 0.0660239914442keywords = neoplasm (Clic here for more details about this article) |
