Granular cell tumors (GCTs) have been described as neoplasms of Schwann cell origin. They are often benign and notably uncommon in the gastrointestinal tract. Recently, their incidence has become more common, likely as a result of increased colonoscopy screenings. Very few data exist regarding their potential for malignancy, but malignant GCTs have been reported. Here, we report the case of a young female patient who was diagnosed with an atypical GCT on the ileocecal valve with an overlying tubular adenoma which was found incidentally on colonoscopy...

BACKGROUND Plasmacytoid is a rare histological variant of urothelial carcinoma (UC). Since the first reported case of plasmacytoid urothelial carcinoma (PUC), in 1991, only about 100 cases have since been reported, with most cases involving the bladder. Urothelial carcinomas of the upper urinary tract represent only 5% of urothelial cancers. To the best of our knowledge, there has only been 1 reported case of PUC of the ureter. PUC is a highly aggressive disease, with a poor prognosis. We present a rare biopsy-proven case of PUC of the ureter with retroperitoneal metastasis...

RATIONALE: Gastrointestinal solitary extramedullary plasmacytoma (EMP) is rare, just occupies about 5% of all EMPs. The most common site is small intestine followed by stomach. The colorectal incidence is much rare. PATIENT CONCERNS: A 63-year-old female had an episodic pain around the umbilicus for about one week. The hyperemia and edema in the ileocecal mucosa were found in colonoscopy, and the endoscopy could not cross the ileocecal valve. The pathology specimens showed a high index suspicion of plasmacytoma...

BACKGROUND: The treatment results of endoscopic submucosal dissection (ESD) for colorectal lesions have improved markedly, but some lesions remain difficult to treat. Hence the cecum is considered a technically challenging site for ESD. We examined the feasibility of ESD for cecal lesions. METHODS: Among a total of 708 colorectal ESD performed in our hospital between March 2006 and December 2016, 549 procedures performed after April 2012 were studied, at a time when the techniques of ESD had stabilized and the procedure was covered by health insurance in Japan...

Although graft-versus-host disease (GVHD) is the major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), cytomegalovirus (CMV) reactivation also occurs in patients after allo-HSCT and these conditions often clinically overlap. The aim of this study was to determine reliable endoscopic findings of CMV colitis in patients with gastrointestinal graft-versus-host-disease (GI-GVHD). Patients after allo-HSCT who were histologically confirmed to have GI-GVHD with or without CMV colitis and patients with an immunosuppressive condition were retrospectively analyzed...

Pyloric gland metaplasia of the ileocecal valve, in the setting of Crohn's disease, is an unusual clinical entity. Though its etiology and pathogenesis remains unclear, metaplastic changes have been associated with chronic inflammation and inflammatory bowel disease. Herein, we report a case of a 23-year-old male who presented for surveillance colonoscopy after being diagnosed with Crohn's disease four years ago. Diagnostic colonoscopy revealed stenosis of the ileocecal valve as well as a 5 mm polypoid circumferential non-obstructing lesion...

An 18-year-old man presented after undergoing multiple investigations for abdominal pain. Retrograde double-balloon enteroscopy showed a protruding red lesion in the ileum with small ulcers, approximately 75 cm proximal to the ileocecal valve, resulting in an intussusception. An inverted Meckel's diverticulum was strongly suspected. Pressure was applied to the protruding lesion using contrast medium injection after wedging the lumen with a balloon. The intussusception partially reduced, avoiding the need for emergent surgery...

An 84-years old woman, medicated with acenocumarol, was admitted to the Emergency Room with lower abdominal pain and nauseas and no history of trauma. She was medicated with acenocumarol and had a non-measurable international normalized ratio. The findings of the bowel ultrasound, ileocolonoscopy and biopsies specimens were suggestive of intramural bleeding of the ileum, ileocecal valve and cecum. Spontaneous intramural bleeding of the gastrointestinal wall associated with oral anticoagulation is rare.

Objectives: Segmented filamentous bacteria (SFB) have been detected in a wide range of different animal. Recently, the presence of SFB-like bacteria was shown in biopsies of the terminal ileum and ileocecal valve of both patients with ulcerative colitis and control subjects. The aim of this study was to verify whether PCR methods could be used for the detection of SFB in biopsy of patients with ulcerative colitis and its relationships with the disease stage. Methods: PCR methods were used to identify SFB in biopsies from the terminal ileum of patients with ulcerative colitis, showing that this approach represents a useful tool for the detection of SFB presence and analysis of the bacterial load...

A 78-year-old man with a history of open sigmoidectomy for sigmoid cancer presented with abdominal pain and vomiting. Abdominal multi-detector CT revealed an obstructive ileocecal tumor with distended small bowel on the oral side. We performed emergency drainage using a transnasal decompression tube, and 2 days later, we conducted a colonoscopic examination, which lead to a provisional diagnosis of obstruction with a malignant tumor invading the ileocecal valve. We then placed a self-expanding metallic stent (SEMS) through the ileocecal valve...

OBJECTIVE: The primary goal in intestinal failure (IF) is adaptation and enteral autonomy (EA). Our goals were to determine the proportion of patients treated for IF by an established intestinal rehabilitation program who achieved EA and to assess the predictors of EA. BACKGROUND: There have been considerable advancements in the management of IF over the last 15 years, children with short bowel syndrome with a reduction in mortality. Several studies have discussed variables that may influence the ability to attain EA; however, majority were written when mortality rates were considerably higher compared with the current contemporary experience...

INTRODUCTION: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors. NET of colon represent less than 1% of colonic tumors. Synchronous liver metastases, present in 75-80%, are considered significant adverse prognostic indicators. Liver is the second commonest site for metastasis in patients with colorectal neuroendocrine tumors. Available treatment options include surgical resection, chemotherapy, biotherapy. Surgery is the gold standard for curative therapy and it is strictly related to the localization, the grade of tumor, and the stage of disease...

Gastrointestinal tuberculosis is a rare and fatal complication in patients with HIV infection. It occurs in 3%-16% of extra pulmonary forms. The main location in 90% of cases is the ileocecal valve and colon. The most unusual presentation of gastrointestinal tuberculosis is massive bleeding with the presence of one or multiple ulcers in the colon. The diagnosis can be confirmed by biopsy and by culture of intestinal tissue. Surgical resection is the treatment of choice. We report a case of a HIV-infected patient, who did not receive antiretrovirals, and who developed disseminated tuberculosis with intestinal perforation, presenting a fatal massive intestinal bleeding...

A 7-year-old girl with an episode of hematochezia and melena, suspicious for bleeding Meckel's diverticulum, was referred for a Tc-99m pertechnetate Meckel's scan. On dynamic planar scan, apart from prompt gastric visualization an oval-shaped, area of inhomogeneous tracer uptake was observed in the left lower quadrant of the abdomen. Subsequent single-photon emission computed tomography/computed tomography localized this to intestinal lumen, thus establishing the diagnosis of intestinal duplication (ID) with functional gastric mucosa...
