A 41-year-old man with no medical history presented with 2 weeks of nausea, vomiting, a new palpable abdominal mass, constipation and a 14kgweight loss. On admission, CT abdomen and pelvis demonstrated a 6.9×3.7 cm soft-tissue abdominal mass deep to and invading the lower anterior abdominal wall with tethering of the urinary bladder and potential involvement of the urachus. Subsequently, a biopsy demonstrated a low-grade spindle cell neoplasm compatible with inflammatory myofibroblastic tumour with immunostain positive for smooth muscle actin and desmin and negative for CD21, CD117, DOG-1, TKE-1, mdm2, CD34 and ALK...

Primary malignant tumors of the small intestine are very rare, accounting for 2%-3% of all gastrointestinal malignancies. Lymphoma constitutes about 15%-20% of all small intestine neoplasms and 20%-30% of all primary gastrointestinal lymphomas. The ileum is the most common site for gastrointestinal lymphomas. Because the symptoms and physical findings are non-specific, the preoperative diagnosis is usually difficult. In this case report, we describe the highly unusual case of sporadic Burkitt lymphoma with complete intestinal obstruction due to intussusception of the proximal jejunum and discuss the treatment options...

Peptide Receptor Radionuclide Therapy (PRRT) is a form of molecular targeted therapy which is performed by using a small peptide (somatostatin analogue - SSA) that is coupled with a radionuclide beta emitting radiation. PRRT is a nuclear medicine for the systemic treatment of non-resectable, metastasized well/moderately differentiated, neuroendocrine tumours (NET) with overexpression of somatostatin receptor. These types of tumours include gastroenteropancreatic neoplasm (GEP-NENs), e.g. arising from the small bowel (often called carcinoid tumours), the pancreas, duodenum or stomach, but also from the large bowel or the lung and many other tissues (so called diffuse neuroendocrine system)...

The majority of malignant melanomas in the small intestine are metastases from primary cutaneous lesions, it can also develop as a primary mucosal tumor in the gastrointestinal tract. In this report, we present rare cases of primary small bowel melanoma and review the current literature. A 78-year-old male presented with abdominal pain and CT enterography identified a ileal mass. A 79-year-old female presented with signs and symptoms of partial small bowel obstruction. Abdominopelvic CT and small bowel series revealed a obstructing mass in the distal jejunum...

INTRODUCTION: Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed...

Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites...

Angiosarcoma is an aggressive mesenchymal sarcoma of endothelial cell origin with high mortality. Its occurrence in the small intestine is exceedingly low. In addition to the rarity of small intestine angiosarcoma, the nonspecific early clinical symptoms obscure the suspicion of such tumors and thereby delay the diagnosis. In a hope to improve the knowledge of this rare but fatal neoplasm, we report one case of angiosarcoma of duodenum and jejunum in a 73-year-old man. Furthermore, we summarize and analyze the common clinical features, tumor markers, treatment, and survival of previous reported cases of this malignancy...

BACKGROUND/AIM: Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLTGT) is a very rare and relatively recently characterized mesenchymal neoplasm arising within the wall of the small bowel, stomach, or large bowel, predominantly in adolescents and young adults. Only few anecdotal reports or small series have been published and a consensus on treatment has not been formulated. Complete resection remains the only curative option for localized disease, but despite optimal surgery, CCSLTGT typically shows highly aggressive behavior with a high rate of local recurrence, metastases, and death from disease...

Crohn's disease (CD) may affect any part of the gastrointestinal tract. When isolated to the colon, and patients become medically refractory, there are several surgical options - segmental resection, subtotal colectomy with ileorectal anastomosis, or a total proctocolectomy and end ileostomy. Unfortunately, surgery does not cure CD, and, regardless of the extent of bowel removed, recurrence may be seen in the small bowel. This may lead to need for further immunosuppression or surgery. Therefore, when appropriate, a segmental colectomy or subtotal colectomy may prevent a permanent ostomy required with a total proctocolectomy...

Signet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum. The symptoms were chronic diarrhea and abdominal pain with a family history of inflammatory bowel disease. The patient underwent surgery and histopathology revealed both aspects of signet ring cell carcinoma and Crohn disease of the ileum...

Malignant neoplasms of the small bowel, especially from the jejunum, are among the rarest types of cancer. Given its location, a delayed diagnosis is frequent and sometimes only made in an emergency context. The authors present a case of intestinal obstruction, where ultrasonography was pivotal in establishing a diagnosis. Point-of-care ultrasonography seems to be particularly sensitive in assessing emergency patients with abdominal pain, allowing effective orientation and saving human and technical resources...

INTRODUCTION AND AIMS: The growing elderly population and wide use of capsule endoscopy have led to a higher number of procedures in those patients. The aim of the present study was to assess the usefulness of capsule endoscopy in older patients. MATERIALS AND METHODS: All consecutive patients undergoing capsule endoscopy at our center within the time frame of 2004-2016 were classified as older (≥75 years of age) and younger. Findings and diagnostic yield were comparatively assessed...

Neuroendocrine neoplasms, including neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs), are rare epithelial tumors with a predominant neuroendocrine differentiation. Compared with NETs, NECs have been reported to be rarer and have a poorer prognosis. We present a rare case of small bowel NEC diagnosed using double-balloon endoscopy (DBE) and the long-term survival accomplished via intensive therapy. DBE revealed an ulcerative tumor in the deep jejunum, and biopsy specimens showed large and highly dysplastic tumor cells; immuno-histological synaptophysin and chromogranin A tests were positive, and the Ki-67 index was more than 90%...

BACKGROUND: The prognostic value of the primary neoplasm responsible for pseudomyxoma peritonei (PMP) remains poorly studied. The aim of this study was to determine the prognosis for patients with extra-appendicular PMP (EA-PMP) treated optimally with complete cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: All patients treated for PMP with CCRS and HIPEC between 1994 and 2016 were selected retrospectively from a French multicentre database...

Goblet cell carcinomas (GCC) are a rare, aggressive sub-type of appendiceal tumours with neuroendocrine features, and controversy exists with regards to therapeutic strategy. We undertook a retrospective review of GCC patients surgically treated at two tertiary referral centres. Clinical and histopathological data were extracted from a prospectively maintained database. Survival analyses utilised Kaplan-Meier methodology. Twenty-one patients were identified (9 females). Median age at diagnosis was 55 years (range 32-77)...

Chromogranin A (CgA) is a well-established marker for diagnosis and follow up of patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN). Recently, it has been shown that plasma levels of CgA correlate with tumor load and predict survival of patients with NEN of the small bowel. It is assumed that this is as well valid for NEN of the colon and rectum, however, this is not supported by data. To evaluate this assumption, we analyzed 62 patients with NEN of the colon and rectum listed in the Marburg GEP-NEN registry for clinicopathological characteristics, expression and plasma levels of CgA...
