Small bowel neoplasm

Mahir Gachabayov, Petr Mityushin
Angioleiomyoma being a type of true smooth muscle gastrointestinal tumors can lead to serious life-threatening gastrointestinal bleeding. We report a case of 21-year-old male patient with recurrent midgut bleeding. Contrast-enhanced CT revealed highly vascular small bowel neoplasm. The patient underwent laparotomy with bowel resection and recovered uneventfully. Histopathology revealed jejunal angioleiomyoma.

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...

Intussusception of small bowel is considered a rare cause of bowel obstruction in adults accounting for only about 1% of bowel obstruction in adults. Intussusception in adults is uncommon with 95% cases of intussusceptions occurring in children. Adult intussusception from small intestinal lymphoma is also rare with only 36 cases reported in the literature between 2000 and 2011. Plasmablastic lymphoma (PBL) is an aggressive lymphoid neoplasm usually seen in the oral cavity in the clinical setting of human immunodeficiency virus (HIV) infection...

Neuroendocrine neoplasmas are a form of cancer arising from cells of diffuse neuroendocrine system. They produce peptides or amines that act as hormones or neurotransmitters. Incidence of NENs is relatively low. Diagnostic work-up and treatment requires a multidisciplinary team approach. The aim of this study was an analysis of data from patients with well-differentiated neuroendocrine neoplasmas of gastrointestinal tract. The study included patients followed up from 1998 to 2013 with histologically confirmed well-differentiated digestive neuroendocrine neoplasm with low or intermediate malignant potential...

BACKGROUND: Stool DNA testing in patients with inflammatory bowel disease (IBD) may detect colorectal cancer and advanced precancers with high sensitivity; less is known about the presence of DNA markers in small IBD lesions, their association with metachronous neoplasia, or contribution to stool test positivity. METHODS: At a single center in 2 blinded phases, we assayed methylated bone morphogenic protein 3, methylated N-Myc downstream-regulated gene 4, and mutant KRAS in DNA extracted from paraffin-embedded benign lesions, and matched control tissues of patients with IBD, who were followed for subsequent colorectal dysplasia...

BACKGROUND: Inflammatory myofibroblastic tumor is a rare tumor of a borderline malignancy. Although it is commonly seen in children, the number of childhood cases in the current literature is limited. The lung is the most commonly affected location. However, cases that have been documented in the mesentery-omentum have mostly been located in the mesentery of the small bowel and not in the antimesenteric edge as in our patient. CASE PRESENTATION: A 6-year-old Greek boy was referred to our hospital with acute abdominal pain mimicking appendicitis...

The small intestine is a relatively privileged organ that only rarely develops malignant or even benign tumors. Given this rarity, the relative inaccessibility of the organ during routine endoscopic procedures, and the typical absence or nonspecific nature of clinical manifestations, these tumors often go undiagnosed. Treatment and prognosis are tailored to each histological subtype of tumor. This chapter will discuss the epidemiology, presentation, diagnostics, and management for the most common small bowel tumors, and will highlight the importance of recognizing patients at higher risk of small bowel neoplasia...

Conservation efforts to preserve the red wolf (Canis rufus) have been in progress since the 1970s through the U.S. Fish and Wildlife Service Red Wolf Recovery Program and the Association of Zoos and Aquarium's Red Wolf Species Survival Plan. An ongoing part of this project has been to monitor mortality trends, particularly to look for potential genetic conditions resulting from inbreeding given the small founding population of only 14 individuals. An initial survey was conducted in the 1990s but a comprehensive assessment of the population has not been done since then...

BACKGROUND: A gap exists between in vivo and ex vivo coagulation when investigated by use of the coagulation tests prothrombin time (PT) and activated partial thromboplastin time (APTT). The thrombin generation assay (TGA) has been developed to fill this gap. CONTENT: TGA evaluates thrombin generation (resulting from the action of the procoagulant driver) and decay (resulting from the action of the anticoagulant driver), thus assessing the balance between the two...

OBJECTIVES: Literature describing the risk factors predisposing inflammatory bowel disease (IBD) patients to anal squamous neoplasia is very scarce. Case reports and small case series have implicated perianal Crohn's disease (CD), long-standing IBD, human papillomavirus (HPV) infection, and immunosuppressive treatment. In this study, we retrospectively examined the association between HPV infection and anal squamous neoplastic lesions among IBD patients from our center. METHODS: We reviewed the pathology records and slides of IBD patients diagnosed with anal squamous cell carcinomas (SCCs), high-grade squamous intraepithelial lesions (HSILs), and low-grade squamous intraepithelial lesions (LSILs) who presented at our center between 1 March 1994 and 9 September 2014...

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. It is a true diverticulum containing all layers of the intestinal wall and identified as a saccular, blind-ending structure located on the antimesenteric border of the distal ileum. Most patients remain asymptomatic during their lifetime. Symptomatic cases are nonspecific and can present as small-bowel obstruction, diverticulitis, perforation, gastrointestinal bleeding, and rarely, a neoplasm. Therefore, the radiological diagnosis is of paramount important for proper patient management...

BACKGROUND: Small bowel tumours are rare and comprise less than 2% of all primary gastrointestinal neoplasms. Among these tumours, a leiomyosarcoma belonging to soft tissue sarcomas is extremely rare and accounts for about 1 % of malignant mesenchymal lesions in the gastrointestinal tract. Due to its aggressive nature and slow growth, it is often diagnosed at the late stage when curative treatment is impossible. Authors report a first case of leiomyosarcoma with chronic recurrent ileocaecal intussusception and literature review to analyse diagnosis and treatment features of the ileum mesenchymal tumours...

Neuroendocrine tumors (NETs), defined as epithelial tumors with predominant neuroendocrine differentiation, are among the most frequent types of small bowel neoplasm. They represent a rare, slow-growing neoplasm with some characteristics common to all forms and others attributable to the organ of origin. The diagnosis of this subgroup of neoplasia is not usually straight-forward for several reasons. Being a rare form of neoplasm they are frequently not readily considered in the differential diagnosis. Also, clinical manifestations are nonspecific lending the clinician no clue that points directly to this entity...

While renal cell carcinoma is the most commonly diagnosed neoplasm of the kidney, its simultaneous diagnosis with a gastrointestinal malignancy is a rare, but well reported phenomenon. This discussion focuses on three independent cases in which each patient was diagnosed with renal cell carcinoma and a unique synchronous gastrointestinal malignancy. Case 1 explores the diagnosis and surgical intervention of a 66-year-old male patient synchronously diagnosed with clear cell renal cell carcinoma and a carcinoid tumor of the small bowel...
