Inflammatory myofibroblastic tumor of the transverse colon with synchronous gastrointestinal stromal tumor in a patient with ulcerative colitis: a case report.

INTRODUCTION: Inflammatory myofibroblastic tumor (IMT) is a rare proliferative disease of uncertain etiology, characterized by the proliferation of fusate or epithelioid myofibroblasts admixed with predominantly mononuclear inflammatory cells. IMT is generally considered a benign lesion, although in some cases this neoplasm has shown an aggressive behavior in terms of local recurrence and metastasis. We report the case of a patient with a ten-year history of ulcerative colitis affected by IMT of the transverse colon and by synchronous gastrointestinal stromal tumor (GIST) of stomach. PRESENTATION OF CASE: A 59-year-old woman with a ten-year history of ulcerative colitis has been admitted to our hospital with signs and symptoms of acute recurrence of ulcerative colitis: abdominal pain, diarrhea, hematochezia and rectal tenesmus. Colonoscopy showed a left colon with diffuse hyperemia, mucosal erosions and a 2-cm, irregularly shaped, polypoid lesion at the level of the transverse colon. Histopathological examination of the specimen obtained via biopsy of the polypoid lesion has revealed a mesenchymal neoplasm with uncertain characters of malignancy. Due to the severity of the inflammatory bowel disease resistant to immunosuppressive and steroid drug treatment, surgical indication was given. DISCUSSION: Although the relationship between IMT and Crohn's disease has been widely reported in literature, the relationship between IMT and ulcerative colitis has never been previously described. CONCLUSION: To the best of our knowledge, this is the first case of IMT associated with ulcerative colitis reported in literature and the synchronous association with a gastric GIST represents another primacy.

Over the past three decades, non-operative management has been shown to be an effective therapeutic option in hemodynamically stable patients. We retrospectively reviewed the last 7 years of our experience with the non-operative management of blunt abdominal traumas. From January 1998 to July 2005, 123 patients with blunt abdominal traumas and injuries to the spleen, liver and pancreas were admitted to our hospital. Fifty-eight of them (47.2%) were submitted to non-operative management; 5 (8.6%) presented associated splenic and hepatic injuries. We performed non-operative treatment for 27 splenic injuries (33.7% of all splenic injuries), 32 hepatic injuries (62.7% of all hepatic injuries) and 3 pancreatic injuries (75% of all pancreatic injuries). There was no mortality and no complications. We submitted one haemodynamically stable patient who presented a grade V hepatic injury and "contrast pooling" at abdominal CT scan to angiography and transarterial embolisation; this patient was successfully managed non-operatively. The overall success rate of non-operative management was 98.5%. The only non-operative management failure was a patient with both splenic and hepatic injuries. The success rate for injuries to the spleen was 96.3%, to the liver 96.9% and to the pancreas 100%. We conclude that hemodynamically stable patients suffering intra-abdominal injury can be safely managed non-operatively.
