1/74. Diffuse metastatic infiltration of a carcinoma into skeletal muscle.Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report a patient with rapidly progressive contractures due to metastatic infiltration of a carcinoma of unknown origin into the skeletal muscle. This 61-year-old man presented with a 1-month history of rapidly evolving, painful restriction of mobility of his right arm and his legs. Computed tomography showed diffuse metastatic nodules in all muscles, particularly in the hip abductors. Muscle biopsy revealed extensive infiltration of the muscle with carcinoma cells.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/74. pancreaticoduodenectomy for metastatic tumors to the periampullary region.Although operative resection of metastatic lesions to the liver, lung, and brain has proved to be useful, only recently have there been a few reports of pancreaticoduodenectomies in selected cases of metastases to the periampullary region. In this report we present four cases of proven metastatic disease to the periampullary region in which the lesions were treated by pancreaticoduodenectomy. Metastatic tumors corresponded to a melanoma of unknown primary site, choriocarcinoma, high-grade liposarcoma of the leg, and a small cell cancer of the lung. All four patients survived the operation and had no major complications. Two patients died of recurrence of their tumors, 6 and 63 months, respectively, after operation; the other two patients are alive 21 and 12 months, respectively, after operation. It can be inferred from this small but documented experience, as well as a review of the literature, that pancreaticoduodenectomy for metastatic disease can be considered in selected patients, as long as this operation is performed by experienced surgeons who have achieved minimal or no morbidity and mortality with it.- - - - - - - - - - ranking = 0.16666666666667keywords = carcinoma (Clic here for more details about this article) |
3/74. Ossifying intramuscular metastasis from colon cancer: report of a case.PURPOSE: This report presents a patient who developed severe buttock pain because of an ossified intramuscular metastasis from a sigmoid colon cancer. methods: This is a case report and review of the literature for intramuscular metastasis from colon cancer. RESULTS: Computed tomography and magnetic resonance imaging showed a soft-tissue mass with heavy calcification. Histologically, mature compact bone was observed with adenocarcinoma cells dispersed among the bony trabeculae. CONCLUSION: When an intramuscular mass is seen, even if it contains extensive calcification, metastasis from colon cancer should be included in differential diagnosis.- - - - - - - - - - ranking = 0.19428482815531keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
4/74. Bilateral pulmonary resection for lung metastases: report of two cases.Resection of bilateral pulmonary metastases is exceptional. However, in carefully selected patients extensive resections might be successfully performed. We report two patients who underwent a pneumonectomy and excision of pulmonary metastases in the other lung, via a left wedge resection for patient 1 and left segmentectomy for patient 2. Resections were carried out for metastases of a malignant fibrous histyocytoma and for a teratocarcinoma. Both patients are still alive 9 months and 4 years after their last metastasectomy, respectively.- - - - - - - - - - ranking = 0.16666666666667keywords = carcinoma (Clic here for more details about this article) |
5/74. Skeletal muscle metastasis from carcinoma of the bladder.Metastasis to skeletal muscle from carcinoma of the bladder is extremely rare. To the best of our knowledge, there is no reported case in the English literature. In this report, we describe a 41-year-old man with bladder carcinoma with metastasis to the right deltoid muscle.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
6/74. An unusual cause of thigh pain in colonic cancer. Inflammatory oncotaxis?Colonic carcinoma metastasis in order of frequency to the liver, lung, bone and brain. Metastases elsewhere are unusual. We report a very rare case of metastatic spread to skeletal muscle and skin. There follows a review of the theories of anomalous metastatic localization. Inflammatory oncotaxis is offered as the most likely explanation of this phenomenon. The importance of good history taking in colorectal cancer follow up clinics is emphasised.- - - - - - - - - - ranking = 0.16666666666667keywords = carcinoma (Clic here for more details about this article) |
7/74. Malignant intramuscular forearm tumor with overwhelming squamous element.Squamous cell carcinoma (SCC) arising in the skeletal muscle is rare. A case of a 19-year-old female patient with an intramuscular forearm tumor showing a histopathologically overwhelming squamous element is presented. Microscopic examination revealed the classical features of SCC, including horn pearls, individual cell keratinization and intercellular bridge. A malignant spindle cell component was not detected. Neither evidence of another primary site nor skin lesion over the tumor was found and no metastatic lesion was detected in the 5 years since the appearance of the mass.- - - - - - - - - - ranking = 0.16666666666667keywords = carcinoma (Clic here for more details about this article) |
8/74. Contemporaneous bilateral forearm triceps metastases from adenocarcinoma of the lung.Haematogenous skeletal muscle metastases from non-small-cell lung cancer (NSCLC) are rare, and are even more uncommonly observed bilaterally. Usually, NSCLC metastasizes to the liver, adrenal glands, lung, bone, central nervous system and kidney. We report a case of a long-surviving patient with contemporaneous histologically proven bilateral muscle metastases in the right and left forearm triceps, from adenocarcinoma of the lung.- - - - - - - - - - ranking = 0.97142414077655keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
9/74. Metastatic non-small cell lung carcinoma with involvement of extremity musculature: case report and review of the literature.Hematogenous dissemination of non-small cell lung carcinoma (NSCLC) metastatic to skeletal musculature in the absence of osseous involvement is an infrequent occurrence. We retrospectively reviewed our institution's indexed database for patients evaluated from 1975 through 1997 who were diagnosed as having skeletal musculature metastases from NSCLC. Eight men and 2 women were identified (age range, 51-80 years at time of metastases). Four primary adenocarcinomas, 4 primary lung squamous cell carcinomas (SCCs), and 2 poorly differentiated primary NSCLCs were identified. Approximate tumor sizes ranged from 10 cm3 to 288 cm3. External-beam radiation therapy was used in 7 of 10 cases; complete surgical excision was performed in 3 cases. patients with known neoplasm who have extremity pain and negative findings on bone scan should be evaluated for soft tissue tumor involvement because such findings significantly affect clinical management. One case of lung SCC metastatic to the quadratus femoris muscle in a 63-year-old man is discussed in detail.- - - - - - - - - - ranking = 1.1942848281553keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
10/74. Metastasis to the forearm skeletal muscle from an adenocarcinoma of the colon: report of a case.While the liver and lung are primary targets for distant metastasis from colorectal carcinoma, metastasis in other distant sites is rarely found. We report herein an unusual case of metastasis to the skeletal muscle of the right forearm from an adenocarcinoma of the transverse colon. A 60-year-old man was originally admitted to our hospital for surgical treatment of an intestinal obstruction caused by a transverse colon carcinoma. Transverse colon resection along with lymph node dissection was performed and no evidence of distant metastatic foci was found. angiography-enhanced computed tomography scanning done 14 months after the first operation revealed multiple hepatic metastases which were resected. A metastasis was subsequently detected in the right extensor carpi ulnaris muscle 2 years after the primary resection, and a major part of the right extensor carpi ulnaris and the extensor digiti minimi muscle were resected, warranting a sufficient margin of 5 cm of normal tissue from the tumor. Reattachment of the residual muscles into the ulna was performed. Metastases to bone and/or soft tissues from colorectal carcinomas are extremely rare and to our knowledge, only eight other cases have been reported in the world literature. This low incidence may be related to the anatomical characteristics and/or the biochemical environment of the skeletal muscle, but it is also possible that the true incidence is underestimated. Recent improvements in interventional radiological procedures may facilitate a diagnosis of skeletal muscle metastasis being made more frequently.- - - - - - - - - - ranking = 1.4714241407766keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
