Abstract
Colorectal polyps are common, and their diagnosis and classification represent a major component of gastrointestinal pathology practice. The majority of colorectal polyps represent precursors of either the chromosomal instability or serrated neoplasia pathways to colorectal carcinoma. Accurate reporting of these polyps has major implications for surveillance and thus for cancer prevention. In this review, we discuss the key histologic features of the major colorectal polyps with a particular emphasis on diagnostic pitfalls and areas of contention.

Abstract
Ischemic colitis, a potentially reversible pathology of the colon, can masquerade in its presentation as colonic carcinoma. It typically presents with cramping abdominal pain, diarrhea, and per-rectal bleeding. Colonoscopy remains the diagnostic modality of choice that typically shows friable, edematous, or erythematous mucosa with scattered hemorrhagic erosions or ulcerations. Although rare, the colonoscopic findings can sometimes reveal a tumor mass that confounds the diagnosis of ischemic colitis as colonic carcinoma. Our patient was a 78-year-old female with no previous colon cancer screening who presented with a mass-forming variant of ischemic colitis. Due to the overlap in presentations, radiographic findings, and colonoscopic findings, the diagnostic challenge was evident. Ultimately, colon cancer was ruled out through thorough colonoscopic follow-up and biopsy-guided pathological analysis. This case signifies the importance of considering colonic mass as a guise of underlying ischemic colitis to ensure an accurate diagnosis and the best possible outcome for the patient.

Abstract
Ischemic colitis (IC) is an underreported chronic disease characterized by the hypoperfusion of the bowel mucosa. The diagnosis and treatment may be challenging because its clinical course resembles other colitis or even colorectal malignancies. This paper reports an untypical case to underline the diversity of IC manifestation. A 68-year-old man with several comorbidities was admitted because of abdominal pain with a 6-month duration and a mass in the left lower quadrant. Colonoscopy revealed erosive pseudomembranous colitis narrowed colon segments with ulcerated mucosa mimicking colorectal cancer and inflammatory bowel disease. The stool cultures and Clostridium difficile toxin tests were negative. After the failure of conservative therapy, the Hartmann procedure with temporary ileostomy was performed uneventfully. The histological results of the surgical specimens revealed IC with focal pseudomembranous areas.

Abstract
Ischemic colitis (IC), the most common gastrointestinal ischemia, remains an enigmatic disease with a wide array of pathogenic mechanisms and injuries along with variable outcomes. Among this group, isolated right colon ischemia (IRCI) appears to be a distinct entity, with its own pathophysiology, clinical presentation, and higher morbidity and mortality compared to left-sided colitis. IRCI is the most common site of mass-forming ischemic colitis. Colonoscopy with biopsy remains the key to diagnosis for this former entity. IRCI management is the same as for other IC and complete resolution of the mass is expected within weeks.

Abstract
PURPOSE Ischemic colitis (IC) is the most prevalent ischemic injury of thegastrointestinal tract. Clinical features of IC such as acute abdominal pain, hematochezia,and diarrhea are similar to those of acute mesenteric ischemia, inflammatorybowel disease, or infectious bowel disease, and their relative ambiguity candelay diagnosis and treatment. To comprehensively detail the current state ofdiagnostic methods and available drug therapies for detecting and treating IC,this review aims to provide a concise and practical summary of thecorresponding literature. METHODS PubMed and Cochrane Library were searched toretrieve all published studies reporting the diagnostic methods and drugtherapies in patients with ischemic colitis. The search strategy of drugtherapy includes human and animal data. RESULTS Colonoscopy combined with histopathologicalbiopsy is the standard of diagnosis for the IC. Most patients respond well tothe conservative treatment, and surgical consultation is needed when conservativetreatment is ineffective. Studies of potential drug therapy have beendeveloped, including phosphodiesterase type 5 inhibitors, pentoxifylline,rebamipide, prostaglandin E1, and polydeoxyribonucleotide. CONCLUSION Accurate diagnoses and effective treatmentshave helped reduce the mortality rate and improve prognoses for patientsafflicted with IC, and corresponding drug therapies have been constantlyupdated as new research has emerged.

Abstract
A wide variety of non-neoplastic conditions may be encountered on colorectal biopsy encompassing idiopathic, infectious, vascular and immune-mediated aetiologies. Although interpretation of such biopsies may be challenging, appreciation of the dominant pattern of injury and subsequent host response may allow for a more focused histological diagnosis in the correct clinical and endoscopic setting. This article aims to provide a systematic, methodical approach to the assessment of such biopsies, concentrating mainly on diagnoses other than inflammatory bowel disease.

Abstract
Colon ischemia (CI) is the most common ischemic disorder of the gastrointestinal tract. Although some markers of CI, such as procalcitonin and alkaline phosphatase, have been reported, few specific serum markers have been identified. We investigated whether serum stromal cell-derived factor-1 (SDF-1) is a specific marker of CI and clarified the relationship between serum SDF-1 level and CI according to a history of combined chronic cardiovascular disease (CVD).We measured SDF-1 level and other serological markers in 84 patients (control, n = 20; CI without chronic CVD, n = 21; chronic CVD without CI, n = 20; CI with chronic CVD, n = 23).Patients with CI were older than those without CI. There were more women in the CI groups than those without CI. At admission, SDF-1 level was significantly higher in patients having CI with chronic CVD (P < .001) than in other groups. SDF-1 level was significantly higher at admission than at discharge in patients having CI with chronic CVD (P < .001) but not in patients having CI without chronic CVD. SDF-1 level did not differ according to symptoms, involved sites, or duration of hospitalization. At a cutoff value of 0.5 pg/mL for the SDF-1 level in patients having CI with chronic CVD, the sensitivity and specificity for SDF-1 were 91.3% and 95%, respectively. The area-under-the-curve (AUC) value was 0.95. In the logistic regression analysis, an elevation of the SDF-1 level to >0.5 pg/mL was a significant indicator of CI with chronic CVD [odds ratio (OR), 114.914; 95% confidence interval, 10.51 to >999.999; P < .001].SDF-1 could be a useful early biomarker for the diagnosis of CI in patients with chronic CVD.

Abstract
A 69-year-old man was admitted to Hanawa Kousei Hospital with acute hepatitis attributed to alcohol consumption. His condition improved with conservative treatment. Computed tomography (CT) showed localized thickening of the colonic wall at the splenic flexure;carcinoembryonic antigen level was slightly elevated to 9.7 ng/mL. Colonoscopy (CS) showed an ulcerative lesion in the colonic splenic flexure. Ischemic colitis (IC) and type 4 colon cancer were suspected, but biopsy was not confirmatory. Malignancy could not be ruled out by contrast-enhanced CT;repeat CS showed circumferential stenosis of the colonic splenic flexure. Ischemic colitis was suspected based on changes between the first and second CS. Biopsy histopathology led us to diagnose stricture-type IC. Constipation, but not intestinal obstruction, occurred. Conservative treatment improved the stenosis. Excessive alcohol consumption may lead to IC;imaging studies may be useful to distinguish IC from colon cancer. Since most cases of ischemic colitis can be improved with conservative treatment, patients with stricture-type ischemic colitis may also be treated without surgery early on, with follow-up that includes careful, periodic imaging.

Abstract
Ischemic colitis (IC) results from reduced colonic vascular perfusion, accounting for 50-60% of all gastrointestinal ischemic episodes. IC leads to mucosal damage with clinical symptom severity developing based on the duration and extent of colonic injury. In rare cases IC may form a mass-like lesion mimicking malignancy. Here we present the case of a 55-year-old female with hematochezia and diarrhea, who on workup was found to have a mass-like lesion at the ileocecal valve. Multiple biopsies demonstrated ischemic change and mucosal injury without evidence of dysplasia or carcinoma. Two months later on follow-up imaging, after supportive treatment the lesion was completely resolved. It is critical for gastroenterologists and pathologists to be aware of this variant of IC to avoid unnecessary surgical procedures and treatment of patients.

Abstract
PURPOSE OF REVIEW To provide an update on the epidemiology, pathophysiology, clinical presentation, and management of colonic ischemia. RECENT FINDINGS Formerly regarded as a rare cause of lower gastrointestinal hemorrhage, colonic ischemia is now recognized to be the most common manifestation of intestinal vascular compromise. In contrast to ischemic events in the small intestine wherein thrombotic and embolic events predominate, colonic ischemia typically results from a global reduction in blood flow to the colon and no occlusive lesion(s) are evident. Several risk factors for colonic ischemia have been identified and, together with an appropriate clinical presentation and patient demographics, create a context in which the clinician should have a high level of suspicion for its presence. Imaging with computerized tomography, in particular, may be highly supportive of the diagnosis, which where appropriate can be confirmed by colonoscopy and colonic biopsy. For most patients, management is supportive and noninterventional, and the prognosis for recurrence and survival are excellent. SUMMARY Colonic ischemia is a common cause of lower abdominal pain and hemorrhage among the elderly typically occurring in the aftermath of an event which led to hypoperfusion of the colon. For most affected individuals the ischemia is reversible and clinical course benign.
