A 62-year-old man presented with upper abdominal discomfort underwent upper gastrointestinal endoscopy. Gastroscopy and endoscopic ultrasonography revealed a submucosal tumor (SMT) with homogenous echogenicity originated from extragastric organs. An abdominal contrast-enhanced computed tomography (CT) showed that the well-marginated ovoid mass, approximately 6 cm in diameter, enhanced homogenously to a similar degree as splenic parenchyma. 99mTechnetium sulfur colloid scintigraphy revealed the splenic nature of the mass. A diagnosis of accessory spleen mimicking gastric SMT was made. Subsequent follow-up was uneventful without performing splenectomy. 相似文献

Tuberculosis is a major health problem in India. Gastrointestinal tuberculosis is the sixth most common causes of extrapulmonary tuberculosis and it mostly involves the ileocaecal region. Primary gastric tuberculosis in immunocompetent person is very rare. Stomach as its site is rare and is the sixth most common site of gastrointestinal tuberculosis. It mostly presents as a cases of non healing ulcer or gastric outlet obstruction. Yield of endoscopic biopsies for granuloma is low due to submucosal location of these lesions and mostly they are diagnosed after surgical intervention. We report a case of isolated gastric tuberculosis in a middle age immunocompetent female who present as a cases of non healing ulcer and responded well to standard antitubercular treatment. A high index of its suspicion should be kept in mind in any chronic infiltrative lesions of stomach like non healing ulcers and gastric outlet obstruction for its early diagnosis and treatment. 相似文献

Human sparganosis is a rare parasitic disease caused by infection with the tapeworm Sparganum, the migrating plerocercoid(second stage) larva of Spirometra species. Sparganosis usually involves subcutaneous tissues and/or muscles of various parts of the body, but involvement of other sites such as the brain, eye, peritoneopleural cavity, urinary track, scrotum, and abdominal viscera has also been documented. Infections caused by sparganum have a worldwide distribution but are most common in Southeast Asia such as China, Japan, and South Korea. Rectal sparganosis is an uncommon disease but should be considered in the differential diagnosis of unusual and suspicious rectal submucosal tumors. We report a case of rectal sparganosis presenting as rectal submucosal tumor. We performed endoscopic submucosal dissection of the rectal submucosal tumor. The sparganosis was confirmed based on the presence of calcospherules in the submucosal layer on histological examination. Moreover, the result of the immunoglobulin G antibody test for sparganosis was positive but became negative after endoscopic submucosal dissection. Though rare, rectal sparganosis should be considered in the differential diagnosis of rectal submucosal tumor-like lesions. This case suggests that physicians should make effort to exclude sparganosis through careful diagnostic approaches, including detailed history taking and serological tests for parasites. In this report, we aimed to highlight the clinical presentation of Sparganum infection as a rectal submucosal tumor. 相似文献

A case of stomach carcinoma showing the features of a submucosal tumor (SMT) is reported. The patient was a 65-year-old woman admitted to the Internal Medicine Department with autoimmune hepatitis and complaining of anemia and tarry stools. Endoscopy revealed a submucosal tumor-like lesion with central ulceration. The lesion was the suspected cause of the anemia; therefore, a partial resection of the stomach was performed. The histopathologic examination revealed a mucinous adenocarcinoma (MUC). The tumor extended to the submucosa. Accordingly, a subtotal gastrectomy with regional lymph node dissection was performed. In stomach carcinoma simulating an SMT, generally preoperative diagnosis is important. However, in this patient, surgery was selected as the best treatment. 相似文献

Gastric tuberculosis is rare and usually presents as an ulcerated lesion or gastric outlet obstruction. Rarer presentations include massive gastrointestinal bleed and gastric perforation. A case of gastric tuberculosis presenting as linitis plastica is reported here. This is the first such case report. The patient was a young woman who presented with non-specific abdominal pain and significant weight loss. The gastric mucosa appeared oedematous and hyperaemic and there was spontaneous oozing of blood on upper gastrointestinal endoscopy. Computed tomography of the abdomen revealed diffuse thickening of the gastric wall. The diagnosis was confirmed by the presence of caseating granulomas with acid fast bacilli in the endoscopic biopsy specimen. The patient showed significant clinical improvement on four-drug anti-tuberculous treatment. 相似文献

The World Health Organization describes calcifying fibrous tumors(CFTs) as rare, benign lesions characterized by hypocellular, densely hyalinized collagenization with lymphoplasmacytic infiltration. These tumors rarely involve the gastrointestinal(GI) tract. A routine endoscopic upper gastrointestinal screen detected a 10-mm submucosal tumor(SMT) in the lesser curvature of the lower corpus of the stomach of an apparently healthy, 37-year-old woman with no history of Helicobacter pylori infection. Endoscopic ultrasonography(EUS) localized the internally isoechoic, homogeneous SMT mainly within the submucosa. Malignancy was ruled out using endoscopic submucosal dissection(ESD). A pathological examination confirmed complete resection of the SMT, and defined a hypocellular, spindle-cell tumor with a densely hyalinized, collagenous matrix, scattered lymphoplasmacytic aggregates as well as a few psammomatous, dystrophic calcified foci. The mass was immunohistochemically positive for vimentin and negative for CD117(c-kit protein), CD34, desmin, smooth muscle actin(SMA) and S100. Therefore, the histological findings were characteristic of a CFT. To date, CFT resection by ESD has not been described. This is the first case report of a gastric calcifying fibrous tumor being completely resected by ESD after endoscopic ultrasonography. 相似文献

Gastric abscess is a rare disorder with approximately 500 cases reported. Two variants are seen diffuse (Phlegemous) or localized. We report a spindle cell tumor (leiomyosarcoma) presenting as a localized gastric wall abscess. 相似文献
