Smooth muscle gastric tumors represent 2% of resected neoplasms of the stomach. Clinically, they are often silent and incidentally found at endoscopy or radiologic examination. These tumors can be histologically classified as benign (leiomyoma) or malignant (leiomyoblastoma), but clinical behavior is not strictly related to this classification. When symptomatic, they are present with anemia in 50% of cases due to mucosal ulceration. Surgical removal of the tumor is the accepted therapy, leaving a margin of surrounding free tissue: this treatment can be performed by laparoscopy, usefully associated with gastroscopy. We present one case of a patient with severe anemia due to bleeding from an ulcerated leiomyoblastoma 5 cm in diameter that we resected with combined gastroscopic-laparoscopic technique. We isolated the portion of gastric wall where the mass was located and resected the specimen under gastroscopic control. The postoperative period was uneventful, and the patient recovered promptly with minimal pain and discomfort.  相似文献

We report a case of large leiomyoblastoma of the jejunum. The sagittal views in pre-operative magnetic resonance imaging (MRI) indicated that a cystic tumor with solid component was present, sequential from the small bowel. We suspected a smooth muscle tumor of the small bowel, but did not rule out the malignancy. The operative diagnosis was smooth muscle tumor of the proximal jejunum, and partial resection of the small bowel was performed. The pathological examination revealed benign leiomyoblastoma of the jejunum without metastasis. MRI contributed to the pre-operative diagnosis of the origin of this rare tumor, in a non-invasive fashion.  相似文献

Medial medullary infarct is a rare type of brain stem infarction first described in 1908. It was only since the broad use of MRI that an accurate clinical topographical correlation could be documented in survivors. We observed two patients; one of them had an anteromedial unilateral infarction in the upper medulla, and the clinical picture was characterized by contralateral hemiparesis, facial weakness, dysarthria and palatal weakness. The outcome was good. The second patient however showed a severe tetraparesis with only minor brain stem signs, secondary to bilateral anteromedian infarction with a large craniocaudal extension. He survived with severe residual impairment. The most likely cause of infarction was arteriosclerosis of the A. vertebralis and A. spinalis anterior, respectively. These two different cases suggest that the medial medullary syndrome is heterogeneous comprising small unilateral infarctions with mild clinical signs as well as large bilateral infarctions with a poor outcome.  相似文献

Devascularization of the lower esophagus and the upper stomach is one method of treating patients with clinically significant gastric varices. We describe a new method of laparoscopically-assisted devascularization which has been applied in seven patients with esophagogastric varices. Three of the seven patients had an episode of gastric variceal bleeding, and the remaining four had moderate to large gastric varices with red color signs. The operative procedure was carried out without pneumoperitoneum by using an ordinary forceps and laparoscopic instruments through a small skin incision (3-5 cm); the abdominal wall was elevated with a U-shaped retractor. The operative field was obtained by laparoscopic and direct vision illuminated by laparoscopic light. The procedure time ranged from 100 to 180 minutes with minimal blood loss (70-320 g). No complications were encountered. All patients could be discharged within one week; postoperative pain was minimal and all patients returned to work early. Follow-up (mean 11.4 months) showed no recurrence of gastric varices although, due to an incomplete procedure in two cases, two patients were treated additionally by endoscopic injection of histoacryl.  相似文献

A case of a gastric small cell carcinoma discovered incidentally by screening ultrasonography is presented. Ultrasonography demonstrated a subcardial metastatic lymph node and multiple hepatic metastatic lesions. Upper GI series and gastroendoscopy revealed a large ulcerated tumor in the cardia of the stomach, and a Borrmann type II tumor, 4 x 2.5 cm, was found in the resected stomach. We describe the radiological findings of the upper GI series, ultrasonography, CT, and gastroendoscopy, and review the literature.  相似文献

Microcinematographic documentation of mitoses, amitoses, endomitoses, or cytoplasmic fusion shortly after completion of mitoses was done in bone marrow specimens of patients with quantitative platelet disorders and controls. In patients with platelet disorders, most mitoses with cell duplication occurred in large promegakaryocytes after 4-fold nuclear and cytoplasmic enhancement. Normal specimens showed polyploidization happening in small megakaryoblasts, while mitoses with cell duplication were seen only after cultivation in freeze-thawed sera of patients with platelet disorders. Frequently, lymphocytes were observed to contact megakaryoblastic cells undergoing mitoses, amitoses and endomitoses and to enter the cytoplasm of megakaryocytes (emperipolesis), leaving it again after several hours.  相似文献

Two patients with ectopic liver are described. In one patient, a small ectopic liver attached to the gastric serosa developed hepatocellular carcinoma (HCC). The preoperative diagnosis was an alpha-fetoprotein (AFP)-producing carcinoma and a malignant ulcer of the stomach. Total gastrectomy and esophago-jejunostomy were performed. The tumor that measured 4 x 2 x 2 cm contained an AFP-producing HCC and normal liver tissue. In another patient who had alcoholic cirrhosis, ectopic liver on the serosa of the gallbladder was found to have the same histological changes as the mother liver. A survey of the literature disclosed more than 20 cases in which HCC developed outside the liver; the liver did not have HCC. By contrast, there was only one report on HCC occurring in the liver in the presence of a noncancerous, relatively large accessory liver lobe. Because ectopic liver does not have a complete vascular and ductal system as a normal liver, it is perhaps functionally handicapped and more prone to hepatocarcinogenesis.  相似文献

Although most subdural hematomas are considered to be venous in origin, they may also be of arterial origin. When subdural bleeding is due to the rupture of an intracranial aneurysm, most commonly at the middle cerebral or internal carotid arteries, the amount of subdural blood is usually small and of no clinical importance. We describe two patients with subdural hematomas secondary to rupture of an intracranial aneurysm, who needed prompt surgical treatment. The first patient had a left internal carotid artery aneurysm at the origin of the ophthalmic artery. In the second patient the aneurysm was at the anterior communicating artery and rebled into the subdural space directly through a right intraparenchymatous frontobasal hematoma. The most probable mechanism of subdural bleeding in our two patients was the existence of adhesions between the aneurysm and the arachnoid due to previous minor hemorrhages. The indication of cerebral angiography in a patient with subdural hematoma is based mainly upon the existence of meningeal signs, the presence of blood in more than one intracranial compartment or the rapid progression of bleeding.  相似文献

Smooth muscle tumors of the alimentary tract are uncommon. A retrospective study was made of 7 patients treated for leiomyosarcoma of the small and large bowel to identify prognostic factors that influence results. The symptoms associated with these tumors varied according to the anatomic sites of the lesions and the position of the growth in relation to the intestinal lumen but the most common presenting clinical signs are bleeding or obstruction. The differential diagnosis between benign and malignant smooth muscle tumors is sometimes quite difficult. Clinical behavior of the myosarcomas of the gastrointestinal tract can be predicted to a large extent by the site of the tumor, the presence or absence of invasion of adjacent vital organs, and the histopathologic grade of malignancy. Although the mitotic activity of a gastrointestinal stromal tumor remains the most critical prognostic factor, tumors have been seen to recur locally and to metastasize even with rare or absent mitotic figures. Further studies are needed to pinpoint the factors that may be correlated to the prognosis.  相似文献

Left ventricular myxoma is very rare. To our knowledge, only 26 cases have been reported in the English and 7 cases in the Japanese literature. A 71-year-old man in our care was being followed due to angina pectoris. Two-dimensional echocardiography revealed a small mass in the left ventricular outflow tract. An operation was performed under cardiopulmonary bypass on July 14, 1992. A small mass located on the anterior wall of the left ventricle was excised en bloc via a transaortic approach. The gelatinous mass measuring 24 x 12 x 3 mm was determined histopathologically to be a myxoma. The postoperative course was uneventful and there has been no sign of recurrence so far. Because recurrent cases have been reported in the past, careful follow-up will be performed periodically.  相似文献

Gastric leiomyoblastoma is a rare entity. In this report, we describe the magnetic resonance (MR) appearance of a recurrent gastric leiomyoblastoma 14 years after initial presentation. This tumor was heterogeneous and moderately low signal intensity on T1-weighted images and heterogeneous and moderately high signal intensity on T2-weighted images. The tumor also contained foci of low signal intensity on the post gadolinium images, consistent with areas of necrosis. The mass enhanced mildly and increased in enhancement on the delayed images, consistent with a hypovascular mass. Multiple liver metastases were noted. Magnetic resonance findings were confirmed with surgical specimens.  相似文献

Sarcoidosis of the small intestine is a rarely described complication of systemic sarcoidosis. Although bleeding from sarcoidosis of the esophagus, stomach, and colon has been reported, massive bleeding from this condition in the small intestine has not been previously described. We present here the first case of hemorrhage from a jejunal sarcoid lesion that was unsuspected and undiagnosed until laparotomy with resection was performed. As with most pathologic conditions of the small intestine, preoperative diagnosis is difficult. Furthermore, the refractory nature of bleeding from this lesion made resection necessary in this patient, suggesting the need for similar therapy in other affected patients.  相似文献

Echinococcus granulosus and Echinococcus multilocularis cause liver hydatid disease. One of its most common complications is rupture into the bile ducts; however, penetration of a cyst into a vessel is a very rare complication. We detected a defect (2 x 1 cm) on the wall of the right hepatic vein, in addition to three distinctive ruptures into the bile ducts, in our case. For systemic hypotension due to a bleeding during operation and to repair the vessel wall defect, an urgent right thoracotomy followed by a radial phrenotomy was needed. We were able to reach the operation site easily and repaired the vessel wall with polypropylene suture. Because of the occurrence of these two complications together and the difficulties of the operation, we decided to report this case.  相似文献

A 42-year-old man with Beh?et's disease of the intestinal type and a chronic cholestatic profile is presented. He had oral aphthea, genital ulcer, erythema nodosum, thrombophlebitis and central retinitis during the clinical course. Deep ileal ulcers recurred with massive bleeding and perforation. Cholestatic laboratory findings were also noted in the clinical course. A biopsied liver specimen, taken at the second operation for the ileal ulcer, showed chronic portal inflammation associated with ductopenia and epithelial degeneration of the small interlobular bile ducts, but periductal concentric fibrosis was not found. The patient died of sepsis 7 months after the last laparotomy. Although there was no significant abnormality in the large biliary tract at autopsy, pericholangitis in the small portal tracts and cholestasis were pronounced. Sclerosing cholangitis is one of well-known complications of ulcerative colitis or Crohn's disease. We report herein another rare association of small bile duct damage resembling sclerosing cholangitis with enteritis in Beh?et's disease.  相似文献

BACKGROUND: Ovarian hemangioma is extremely rare. CASE: We report a case of a 32-year-old woman who complained of pelvic pain due to a large right adnexal mass. On color Doppler sonography the mass showed very rich and complex vascularity, with prominent blood flow. A 10 x 8-cm hemangioma of the right ovary was resected. CONCLUSION: Hemangiomas should be considered when a richly vascularized tumor with prominent blood flow is detected on color Doppler sonography or magnetic resonance imaging.  相似文献

Dieulafoy's disease is an unusual cause of gastrointestinal hemorrhage, reported to account for less than 2% of acute gastrointestinal bleeding episodes. Bleeding occurs from a defect in an unusually large submucosal artery, through a minute mucosal erosion. Endoscopic diagnosis is sometimes difficult, but primary endoscopic therapy may be successful and should be attempted. In most cases the lesion is found in the proximal stomach. Sixteen cases of Dieulafoy's lesion located in the colon have been reported in the literature but only nine have been confirmed by histology. We present the case of a 63 year-old male with Dieulafoy's lesion of the transverse colon which was diagnosed by endoscopy and confirmed by histology.  相似文献

A case of adenosarcoma arising from the uterine cervix of a 55-year-old female who complained of vaginal discharge is reported. A polyp, 6 x 2 x 1.5 cm in size, identified in the cervical canal was clinically diagnosed as benign cervical polyp and resected. Histologically, the polyp was composed of benign epithelial components and sarcomatous stroma wherein periglandular hypercellularity and some mitoses including atypical ones were noted. Immunohistochemically, stromal cells were positive for muscle-type actins, desmin and estrogen receptor. Adenosarcoma is a rare, biphasic tumor of the uterus and usually presents as a polypoid mass in the endometrial cavity. When they arise from the cervix, adenosarcomas may be confused with benign cervical polyps clinically and pathologically. As the former often recurs, microscopic differentiation is crucial for further treatment.  相似文献

The authors present a case of Crohn's disease that initially showed common localisations, and later a rare gastro-duodenal involvement. When the definitive diagnosis of the latter was reached there were already signs of obstruction at the exit of the stomach. Treatment with Prednisolone I.M. and Omeprazole was not successful, and surgery was necessary as a last recourse to resolve the obstruction. A theoretic revision of the main clinical, diagnostic, and therapeutic aspects of this rare from of involvement of Crohn's disease is also presented.  相似文献

Malignant fibrous histiocytoma (MFH) in the stomach is very rare, and only four cases have been reported. As a result, there is still little understanding of its clinical and pathological features. We recently experienced two cases of gastric MFH. The first case was a 78-year-old man with epigastralgia and a loss of body weight. Endoscopy revealed an ulcerated submucosal tumor. A gastrectomy was performed and the diagnosis of MFH was made histopathologically. The second case was a 77-year-old man with pulmonary symptoms. An image diagnosis indicated a strong suspicion of lung cancer, and a right middle and lower lobectomy was thus performed. One month after the operation, a bleeding gastric tumor was found and therefore a gastrectomy was performed. Both tumors were diagnosed as MFH. From the analysis of six reported cases including ours, a preoperative correct diagnosis is found to be difficult although the lesion has grown to a considerable size at the time of operation. Since a metastatic lung lesion was first detected in two out of six cases, it is thus recommended that the stomach should be examined when lung MFH is found. Considering the high mortality and the short survival in the six cases, the prognosis for gastric MFH seems to be poorer than that in the extremities. However, lymph node metastasis is uncommon, and a curative resection is possible in some cases such as in our second case.  相似文献

Whipple's disease is a rare, generalized inflammatory disorder due to the recently described bacterium Tropheryma whippelii. We report an unusual, successfully treated case of a 32-year-old woman, who presented with a 25 month history of large abdominal lymphomas, polyserositis and cachexia. The diagnosis of Whipple's disease was confirmed by duodenoscopy, lymph node and duodenal histology and polymerase chain reaction analysis of biopsy material and cerebrospinal fluid. A prolonged convulsive seizure with a subsequent 5 day period of coma were interpreted as signs of cerebral involvement. Under antibiotic treatment with trimethoprim-sulfamethoxazole (co-trimoxazole) the patient recovered completely, CT scans showed a complete regression of abdominal lymphomas. The therapy was continued over 18 months without the occurrence of a relapse.  相似文献
