Gastric polyps are frequently encountered on endoscopic examinations. While many of these represent true epithelial lesions, some of the polyps may result from underlying stromal or lymphoid proliferations or even heterotopic tissue. Histologic examination is essential for accurate typing of the polyps to predict malignant potential and underlying possible genetic abnormalities. The focus of th...
Purpose: The rate of gastrointestinal adenomatous polyps, often regarded as precancerous lesions, developing into cancer is 40 – 70 %. Endoscopic resection has been the preferred method for treating gastric polyps since late 1960s. Surgical removal continues to play an important role in treatment polyps; however, efficacy such cannot be guaranteed, and may recur.Case presentation: Here, we repo...
background: early diagnosis and endoscopic resection of adenomatous polyps is the main approach for screening and prevention of colorectal cancer (crc). we aimed to assess polyp detection rate (pdr) and to characterize demographic, clinical, and pathological features of colorectal polyps in an iranian population. methods: we retrospectively analyzed the data from 5427 colonoscopies performed du...
BACKGROUND/AIMS To investigate missing diagnosis of the polyp by colonoscopy, and to reveal the endoscopic, pathological features of missed polyps and related factors inducing missing diagnosis. MATERIALS AND METHODS We reviewed the data of the patients who received colonoscopy twice within 180 days. The missing rate of the colorectal polyps ware calculated and the endoscopic and pathological...
Fibroepithelial polyps, also named as soft warts, skin tags, or acrochordons, are common benign lesions that may occur on trunk or exterimities. Its association with infectious agents is unclear. Herein, We report a case of extensive fibroepithelial -like polyps on the foot of an AIDS patient following radiotherapy for Kaposi's sarcoma.
To investigate the role of telomerase in the multistep Colorectal carcinogenesis, we examined telomerase activity in 31 adenomatous polyps and 22 paired cancer-normal mucosa specimens from non-hereditary nonpolyposis colorectal cancer patients. Telomerase activity was detected in 18% of normal mucosa, 16% of small «1.0 cm) polyps, 20% of intermediate polyps, 71% of large (>2.0 cm) polyps, and ...
Background and purpose: Colorectal cancer is one of the most common types of cancers worldwide. Most of the times it is superimposed on an adenomatous polyp. Today, colonoscopy is the gold standard screening test for diagnosis of colorectal cancer which prevents developing cancer on the adenocarcinoma sequence path way. The goal of this study was to evaluate the gross and microscopic characteri...
Ileostomy polyps are uncommon and poorly described. The aim of this study was to undertake a retrospective clinicopathological review of ileostomy polyps. Seven patients with 60 polyps arising on ileostomies performed for ulcerative colitis were studied. The histopathological evaluation of archival ileostomy biopsy specimens, polypectomy or excision specimens, and clinical review of patient rec...
it is well known that desensitization treatment with aspirin can significantly improve symptoms and quality of life in patient with aspirin-exacerbated respiratory disease. however, its mechanism has not been clearly understood yet. in this case report, 41-year-old male patient was referred to our allergy and immunology department with complaints of chronic rhinosinusitis including p...
OBJECTIVE To examine the changes that occur in the immunohistochemistry of vasoconstrictor and vasodilator transmitters in nerves supplying early and advanced colorectal polyps. SUBJECTS AND METHODS We studied the perivascular innervation of submucosal arterioles of colorectal polyps (n = 18) and the innervation of the epithelial layer of polyps compared to normal controls (n=8), using immuno...
