Heterotopic bone is rarely found in the gastrointestinal tract. In the majority of reported cases, it was associatedwith malignant lesions [1,2], Peutz–Jeghers syndrome [3], and more rarely with inflammatory colonic polyps [4]. On reviewing the literature, we found only two cases of metaplastic bone accompanying hyperplastic gastric mucosa [5,6], and no case report of osseous metaplasia in gast...
Adenomatous polyposis coli (APC) is best known for its crucial role in colorectal cancer suppression. Rodent models with various Apc mutations have enabled experimental validation of different Apc functions in tumors and normal tissues. Since the development of the first mouse model with a germline Apc mutation in the early 1990s, 20 other Apc mouse and rat models have been generated. This arti...
The course of acalculous adenomyomatosis of the gallbladder in six patients is described. It is suggested that, even in the absence of gallstones, cholecystectomy should be advised when this condition is demonstrated radiographically in symptomatic subjects. The cause of the pain is unknown but it is probably related to excessive neuromuscular activity of the hyperplastic gallbladder wall. One ...
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 ...
Most bowel intussusceptions in adults have a leading point. However, there have been few reports of jejunojejunal intussusception secondary to a solitary juvenile polyp in adult. We report herein the case of a 19-year-old female with a solitary juvenile polyp in the jejunum causing intussusception. Laparoscopic-assisted reduction and segmental resection of the jejunum were successfully done for...
A 60-year-old man with prostatic adenocarcinoma and a synchronous tubulovillous adenomatous polyp of the colon underwent a successful robotic radical prostatectomy combined with a laparoscopic right hemicolectomy. We describe the initial report of this combined, minimally invasive procedure involving separate organ systems and surgical disciplines, and describe our technique.
Turcot Syndrome This section has been reviewed and approved by the Cancer.Net Editorial Board [1], December / 2011 Overview What is Turcot syndrome? Turcot syndrome is a condition in which cells become abnormal and form masses called polyps. A polyp is benign (noncancerous) but can eventually turn malignant (cancerous, meaning it can spread to other parts of the body). Turcot syndrome is rare a...
BACKGROUND Distal diminutive colorectal polyps are common and accurate endoscopic prediction of hyperplastic or adenomatous polyp histology could reduce procedural time, costs and potential risks associated with the resection. Within this study we assessed whether digital chromoendoscopy can accurately predict the histology of distal diminutive colorectal polyps according to the ASGE PIVI state...
Inflammation and oxidative stress play a crucial role in the development of colorectal cancer (CRC) and interference with these mechanisms represents a strategy in CRC chemoprevention. Allopurinol, a safe molecular scavenger largely used as antigout agent, has been shown to increase survival of patients with advanced CRC and to reduce CRC incidence in long-term gout users in epidemiologic studi...
Multiple adenomatous colon polyps. An adenomatous polyp is an area where the normal cells that line the inside of the colon and begin to make mucous and form a mass on the inside of the intestinal tract. Benign (noncancerous) tumors, including: sebaceous cysts (closed sac filled with liquid found under the skin) epidermoid cysts (lumps in or under the skin often filled with liquid) fibromas (fi...
