Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells. We here report a case of stromal tumor of the small intestine in order to analyze it in the light of literature data and imaging results, which may suggest prebiopsy diagnosis as well as its therapeutic and prognostic peculiarities...

Approximately 25-30% of patients with renal cell carcinoma (RCC) have metastatic disease at the time of diagnosis, where the most common sites of metastasis are the lung (50-60% of patients with metastatic disease), bones (30-40%), liver (30-40%), and brain (5%). Although RCC metastasis to the small intestine is thought to be exceedingly rare, with predominantly isolated case reports and a few case series in the literature, we present below three additional cases at our institution of metastatic RCC to the small bowel presenting as GI bleeding...

BACKGROUND: Kaposi's sarcoma (KS) is a vascular tumor arising in association with human herpesvirus-8 (HHV-8) infection, and different variants show different clinical presentations. Isolated intestinal KS in the background of Crohn's disease (CD) is exceedingly rare with only 3 cases reported in the English literature (from 1966 to 2016). CASE PRESENTATION: Herein, we report a case of intestinal KS in a 21-year-old HIV-negative Ethiopian male with a long-standing history of steroid therapy for his underlying IgA nephropathy...

Mesenteric paragangliomas are a rare entity; consequently, only 12 cases have been reported to date. Although considered benign and often found incidentally, they have the potential to metastasize and are an important diagnosis to consider for patients with a mesenteric tumor. We report the case of a 71-year-old woman who was found on magnetic resonance imaging to have an incidental, large, complex, intra-abdominal mass that had initially been misdiagnosed as ovarian in origin. She underwent an open resection of the tumor and adjacent small bowel with no perioperative complications; histology confirmed the mass to be a mesenteric paraganglioma...

Purpose: Pathologic complete response to neoadjuvant chemoradiation therapy (CRT) is associated with improved outcomes for patients with locally advanced rectal cancer (LARC). Increased response rates have been reported with higher radiation doses, but these studies often lack long-term outcome and/or toxicity data. We conducted a case-control analysis of patients with LARC who underwent definitive CRT to determine the efficacy and safety of intensified treatment with a concomitant boost (CB) approach...

RATIONALE: Myeloid sarcomas (MSs) are rare malignant hematological tumors. They most commonly occur in patients with acute or chronic myeloid leukemia. A de novo MS with no evidence of blood system disease is rare, but may represent the first sign of a systemic illness that precedes a full-blown disease. Herein, we report the computed tomography (CT) findings of an extremely rare case of a nonleukemic MS that progressed to acute myelogenous leukemia (AML) and simultaneously involved the small intestine, kidneys, mesentery, and mesenteric lymph nodes...

Despite the proven efficacy of biological drugs for inflammatory bowel disease, these therapies are costly and do carry some risks, providing incentive for exploring strategies to discontinue therapy in patients with prolonged remission. We presently review multiple cohort studies indicating the overall risk of relapse after stopping an anti-tumor necrosis factor (TNF) in inflammatory bowel disease patients is roughly 40% at 12 months after therapy cessation. Despite methodological differences across studies, it appears that patients without deep remission (ie, patients with endoscopic or biomarker evidence of inflammation) are at increased risk of relapse after stopping anti-TNF, as are those with high-adequate levels of anti-TNF before stopping...

In France, upper gastrointestinal haemorrhages have an estimated annual incidence of 143 cases per 100,000 inhabitants. Classically, two types of digestive hemorrhage are described: acute and chronic digestive hemorrhages. Upper endoscopy is carried out in case of hematemesis or melena. It requires that the patient has been fasting for at least 6hours for solids and 3hours for liquids. The main etiologies of hemorrhagic hemorrhage of the origin are the vascular abnormalities, inflammatory or drug-induced ulcerations, intestinal tumors, Meckel's diverticulum, and Dieulafoy ulcer...

Despite being the largest part of the human gastrointestinal (GI) tract, the small intestine accounts for only 1-1.4% of all GI malignancies. Adenocarcinoma is the most common primary small bowel malignancy, with the most common site being the duodenum. On the other hand, squamous cell carcinoma (SCC) of the duodenum is extremely uncommon. We report the first case of mixed adenocarcinoma and SCC occurring in the third part of duodenum (D3). Our patient, a 64-year-old female with history of GERD, hypertension, and IDDM presented with 4 weeks of nausea, vomiting, and abdominal pain...

Neoplasms of the small bowel are rare and comprise only 1-5% of all gastrointestinal neoplasms. The most frequent malignant tumors located in the small bowel are adenocarcinomas, lymphomas and neuroendocrine tumors. Rarely observed are gastrointestinal stromal tumors (GIST), leiomyosarcomas and leiomyomas. Leiomyomas are most frequently seen in the jejunum followed by the ileum and lastly the duodenum. In most cases, a definite diagnosis of these tumors is not possible prior to surgical treatment. The treatment of choice for these tumors is surgery...

Despite the small bowel comprising 90% of the mucosal surface area of the gastrointestinal tract, it is a rare site for neoplasia and only accounts for a little over 3% of the tumors that arise in the digestive tract. Benign small bowel lesions include lipomas, lymphangiomas, leiomyomas, neurofibromas, nodular lymphoid hyperplasia and adenomas, many of which are precursors to malignant lesions. Several polyposis syndromes are associated with small bowel polyps as well, including familial adenomatous polyposis syndrome, lynch syndrome, Peutz-Jeghers syndrome, Cowden syndrome and juvenile polyposis syndrome...

OBJECTIVE: Meckel diverticulum may become symptomatic if it is complicated by hemorrhage, intestinal obstruction, diverticulitis, or tumor. Although classically described in children, it is often missed in adults because of lack of suspicion and difficulty in detection. The purpose of this article is to review the imaging findings and management of Meckel diverticulum and its complications. CONCLUSION: Although it is infrequently encountered incidentally, Meckel diverticulum should be considered especially when interpreting examinations for abdominal pain, small-bowel obstruction, and gastrointestinal bleeding...

The term inflammatory bowel disease (IBD) refers principally to two major categories of chronic relapsing inflammatory intestinal disorders: Crohn's disease (CD) and ulcerative colitis (UC). In the United States, it is currently estimated that about 1.5 million people suffer from IBD, causing considerable suffering, mortality and economic loss every year. Yet the cause of IBD is unknown, and until we understand more, prevention or cure will not be possible. There is a lot of variation in the incidence and prevalence of CD based on geographic region, environment, immigrant population, and ethnic groups...

To date, because of their rarity, the clinicopathological features and surgical outcomes of small bowel adenocarcinomas (SBAs) have been insufficiently explored. We evaluated the clinicopathological features and long-term outcomes of patients who underwent surgery for SBA.This retrospective study (from 1999 to 2016) examined patients with SBA treated surgically at the China National Cancer Center/Cancer Hospital. Clinicopathological features, preoperative evaluation, surgical treatment, and outcome parameters were reviewed and analyzed...
