Methods Blood was collected for PTEN mutation analysis and medical records were requested to document diagnoses. Patients who are PTEN+ with ≥5 GI polyps, ≥1 of which is hyperplastic (hyp) or hamartomatous (ham, n=4) or who met relaxed ICC criteria (n=118) were analyzed. Upper and lower GI endoscopy and pathology reports were reviewed and findings are reported descriptively. Fisher’s 2-tailed e...
Mesenchymal type tumors originated in the submucosa represent a small percentage of colorectal polyps. This is particularly true for polyps composed of more than one mesenchymal tissue type. We herein present the pathological features of an unusual polypoid proliferation of mature fatty, fibrous, and vascular tissues including vessels of diverse nature and size. The histological findings suppor...
Hamartomas are tumour-like malformations, consisting of disorganized normal tissues, typical of the site of tumour manifestation. Familial manifestation of hamartomatous polyps can be noted in juvenile polyposis syndrome (JPS), Peutz-Jeghers' syndrome (PJS), hereditary mixed polyposis syndrome (HMPS) and PTEN hamartoma tumour syndrome (PHTS). All the aforementioned syndromes are inherited in an...
Peutz-Jeghers syndrome (PJS) is an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with mucocutaneous pigmentations. Main symptoms of PJS in childhood are abdominal pain, obstruction, intussusception, and bleeding from hamartomatous polyps. PJS carries a high risk of gastrointestinal cancer with advancing years. Although, intussusception has...
Juvenile polyposis syndrome (JPS; MIM 174900) is an autosomal dominant condition with incomplete penetrance characterized by hamartomatous polyps of the gastrointestinal tract and a risk of gastrointestinal cancer. Gastrointestinal hamartomatous polyps are also present in Cowden syndrome (CS; MIM 158350) and Bannayan-Zonana syndrome (BZS; also called Ruvalcaba-Myhre-Smith syndrome; MIM 153480)....
S38 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 polyps brought out of the CBD with a balloon or a basket and then snared off, and CBD and PD stents were placed. The histopathology showed adenomatous polyps with low-grade dysplasia in three cases and adenofibroma/hamartomatous polyp in one. One patient was found to have underlying malignancy after 2 months. Conclusion: Distal C...

Cowden syndrome is an uncommon, autosomal dominant disease characterized by multiple hamartomas and hyperplastic lesions in the skin, mucous membrane, brain, breast, thyroid, and gastrointestinal tract. About 30% of Cowden syndrome cases are reportedly complicated by malignant diseases. Hamartomatous polyps occur throughout the gastrointestinal tract, the most common sites being the stomach, co...
In children, colorectal polyps most commonly present with rectal bleeding. The aim of this study was to establish some correlations between clinical, endoscopic/ histopathological aspects and therapeutic options in pediatric colorectal polyps. The experimental group included 253 children aged between 1 and 18 years, patients being included based on the presence of rectal bleeding associated wit...
INTRODUCTION Peutz-Jeghers is a rare autosomal dominant disorder characterized by hamartomatous polyps and discoloration of mucosal membranes. The polyps can occur anywhere in the gastrointestinal tract and can grow large enough to cause bowel obstructions. CASE REPORT A 16-year-old male presented to the emergency department with signs and symptoms of an acute bowel obstruction. He had 2 days...
