1/5. Case report: gastroduodenal intussusception of a gastrointestinal stromal tumour.Gastrointestinal stromal tumours (GISTs), previously termed leiomyomas and leiomyosarcomas are relatively common tumours of the gastrointestinal tract, most commonly found in the stomach. Most GISTs are asymptomatic but may cause abdominal pain or bleeding from ulceration of the overlying mucosa. A rare case of gastroduodenal intussusception of a large gastric stromal tumour, which presented with intermittent abdominal pain and gastric outlet obstruction, is reported. Pre-operative diagnosis was made on abdominal CT and confirmed at laparotomy. Pre-operative diagnostic difficulties and management are discussed.- - - - - - - - - - ranking = 1keywords = gastrointestinal stromal tumour, gastrointestinal stromal, stromal tumour, stromal (Clic here for more details about this article) |
2/5. intussusception due to gastrointestinal stromal tumour of the colon: diagnosis by colonoscopy.intussusception of the intestine is rare in adults. We report a case of a 45-year-old male who presented with long-standing pyrexia of unknown origin, abdominal pain, gastrointestinal bleeding and constitutional symptoms. Colonoscopic examination revealed a large invaginated mass suggestive of colonic intussusception due to gastrointestinal stromal tumour of the colon. His symptoms disappeared after surgical removal of the tumour.- - - - - - - - - - ranking = 1.2184556585045keywords = gastrointestinal stromal tumour, gastrointestinal stromal, stromal tumour, stromal (Clic here for more details about this article) |
3/5. Infantile intestinal leiomyosarcoma is prognostically favorable despite histologic aggressiveness: case report and literature review.Intestinal leiomyosarcomas in children are extremely rare. The authors present a case of infantile intestinal leiomyosarcoma of the colon that was resected and was classified histologically as grade 2 because of abundant mitoses. The tumor cells infiltrated the submucosa and the serosal surface. Immunohistochemically, these cells were positive for alpha-smooth muscle actin but not for CD34 or CD117, by which the tumor was differentiated from gastrointestinal stromal tumor (GIST). The patient underwent follow-up without adjuvant therapy and is now doing well with no evidence of the disease for 42 months. Based on the current case and a review of 18 reported cases, it is concluded that infantile intestinal leiomyosarcoma, which is differentiated from GIST, has a favorable prognosis even when the histologic appearance is suggestive of aggressive biological characteristics. Adjuvant therapy is unnecessary when tumors are completely resected.- - - - - - - - - - ranking = 0.087148428883085keywords = gastrointestinal stromal, stromal (Clic here for more details about this article) |
4/5. Neonatal gastrointestinal stromal tumor. Report of a case and review of literature.Gastrointestinal stromal tumor (GIST) is very rare in infancy. Most of the reported cases in the literature are in adults; some are in children but there are a few reported cases in the literature. The present case is a 6-day-old female neonate presenting with lethargy, poor feeding, constipation, abdominal distention, and rectal bleeding. She was operated on with the impression of intestinal obstruction, and right hemicolectomy was performed on her. Surgical specimen showed a well-defined and round 3-cm mass in the cecal area. diagnosis was made by histologic and immunohistochemical studies which showed a GIST. The tumor showed positive vimentin and c-kit but negative for all other markers (desmin, actin, S100, NSE, and CD-34). So the case was an undifferentiated GIST. After 1 year of follow-up the patient was completely normal.- - - - - - - - - - ranking = 0.34914551426162keywords = gastrointestinal stromal, stromal (Clic here for more details about this article) |
5/5. Gastroduodenal intussusception of a stromal gastric tumour.An elderly patient presented with intermittent vomiting. The cause was a gastric tumour causing gastroduodenal intussusception. On excision and histological examination this was found to be a stromal tumour of uncertain malignant potential ('STUMP').- - - - - - - - - - ranking = 0.014824931515317keywords = stromal tumour, stromal (Clic here for more details about this article) |
