Primary small bowel tumors account for 1-6% of all Gastrointestinal (G.I.) tract malignancies. Among these pedunculated lipomas are unusual. We report a case of a 66-year-old male with a history of G.I. hemorrhage and acute anemia, negative upper and lower endoscopies and a pedunculated lipoma in distal ileum, revealed by CT enterography. The patient was successfully treated by open surgery. Patients with G.I. hemorrhage and negative upper and lower endoscopies need an accurate evaluation of small bowel. Multislice CT enterography or Magnetic Resonance enteroclysis/ enterography represent the fastest and more accurate tools to obtain an exhaustive evaluation of small bowel...

REVIEW
Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

The increased use of abdominal imaging has led to a major increase in small renal tumors incidence particularly in the elderly population. Their management is evolving with the development of percutaneous ablation, particularly radiofrequency ablation, cryoablation, and microwave ablation. The typical indications that must be validated by a multidisciplinary committee include solid tumors less than 3cm in patients with multiple comorbidity factors (including age), contraindications to surgery, hereditary renal cancer, bilateral renal tumors, solitary kidney, pre-existing chronic kidney disease, or at high risk of predialysis renal function after partial nephrectomy...

PURPOSE: One of the rarest gastrointestinal neoplasm is small bowel cancer. Experience with its treatment modalities is limited. Stereotactic ablative radiation therapy (SABR) has improved, with image-guided radiation therapy becoming a curative option in many tumors. Especially when surgery cannot be performed due to comorbidities, SABR provides a good toxicity profile and an excellent tumor control rate owing to its specific schedule: high dose on a limited and well-defined area. METHODS: An 83-year-old man had arterial hypertension and congestive cardiomyopathy, with recent history of upper abdominal pain, weight loss over 10 kg, and progressive severe fatigue...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

Brunner's gland adenoma is an extremely rare benign small bowel neoplasm, often discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics. In few cases, it tends to cause gastrointestinal hemorrhage or intestinal obstruction. We report here our experience with a 47-year-old woman with a Brunner's gland adenoma of more than 6 cm in size, located in the first part of the duodenum and causing gastrointestinal bleeding. Initially, we performed a partial endoscopic resection using endoloop and snare alternatively to prevent severe bleeding...

Small bowel tumors are rare tumors. Duodenal tumors occur more commonly compared with other small intestinal tumors. To summarize the clinicopathological features of duodenal tumors, in the present study 44 cases of duodenal tumors were collected, and the comparative clinicopathological characteristics between tumors of the ampulla and non-ampulla, the choice of treatment, and differences in the prognosis, were analyzed. The pathological type identified was predominantly adenocarcinoma; periampullary duodenal tumors were almost classifiable as adenocarcinoma in terms of their type...

Sarcomatoid carcinoma of the small intestine is a very rare and aggressive variant of small intestinal cancers with poor prognosis. The tumour primarily affects middle-aged and older patients with a mean age of 57 years at the time of presentation. We report a woman aged 58 years without any relevant medical history who presented with small intestinal obstruction. She underwent radiologic and endoscopy investigation with persistent features of small bowel obstruction. The patient was found to have a small bowel tumour causing the obstruction and underwent surgical excision of the tumour...

Digestive neuroendocrine neoplasms (DNENs) have an incidence of 2.39 per 100,000 inhabitants per year, and a prevalence of 35 cases per 100,000; the gap between these rates is to be referred to the relatively long survival that characterizes the majority of these tumors, which can be thus considered as chronic oncological diseases. Up to 80% of patients are stage IV since the first diagnosis, presenting a 5-yr overall survival rate of 35%-55% and a twice higher mortality than limited disease. DNENs express somatostatin receptors in more than 80% of cases, detected through immunohistochemistry or functional imaging tests (FITs)...

UNLABELLED: In this article, we reviewed the case of a patient who was object, in 1999, of a published case report of schwannoma of the jejunal wall. Recently, the patient has been referred to our institution for a mass of the stomach identified by upper gastrointestinal endoscopy. The patient underwent a wedge resection of the stomach and a histopathological diagnosis of GIST of the stomach, based on a positive immunohistochemical staining of c-kit and CD34, was made. In consideration of these findings, we performed immunohistochemistry for c-kit and for CD34 on the previous lesion of the jejunal wall, which resulted strongly positive for CD117 and negative for CD34...

INTRODUCTION: Merkel Cell Carcinoma is an aggressively malignant, neuroendocrine-derived, cutaneous neoplasm that commonly affects sun-exposed areas of the elderly population. MCC typically presents as a rapidly enlarging, painless nodule that is red to purple in color and located on sun exposed areas such as the head, neck and arms. Although rare, cases of MCC on non-sun exposed skin have been documented and typically have a worse prognosis. PRESENTATION OF CASE: We report an atypical case of Merkel Cell Carcinoma originating in a non-sun exposed area of the body with evidence of distant metastasis...

BACKGROUND: Inflammatory fibroid polyp (lFP) is a rare, benign, and solitary neoplasm predominantly located in the gastric antrum and small bowel. Its clinical symptoms are heterogeneous and essentially depend on the location and size of the tumor. Definitive diagnosis is made through histopathology and this pathology has excellent long-term prognosis. AIM: To identify the cases of IFP seen at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán over a 10-year period...
