We encountered a 46-year-old woman with synchronous quintuple primary cancers. She did not present with any symptoms, and her tumors were discovered at a gynecological screening. She had clear cell adenocarcinoma of the right ovary, moderately differentiated endometrioid adenocarcinoma of the endometrium, moderately differentiated adenocarcinoma of the ascending colon, well-differentiated adeno...
Adenocarcinoma arising in urinary bladder or prostatic urethra is uncommon. When they occur, the tumor can be mistaken for metastatic lesions, especially from the colon. Here we report the fifth case of a primary urothelial-type adenocarcinoma arising in the prostate which showed enteric differentiation. The patient was a 55 year-old male whose prostatic needle core biopsy showed a high grade a...
Introduction. Ten cases of dome-type adenocarcinoma of the colon have been reported so far. Most of them were presented as early lesions, with endoscopic and microscopic distinguishing features. Methods and Results. A raised plaque was removed from the right colon during colonoscopy in a 56-year-old man. Histopathological examination showed a cancerized adenoma invading the submucosa with sever...
The surgical and anatomical basis for using the colon as a substitute for the esophagus were established in 1911 by Kelling and Vuillet1 and for many years was the technique of choice for esophageal replacement2. Its use is helpful in benign diseases, such as caustic or peptic strictures, and malignancies1,3, especially when the stomach cannot be used, and also in children with congenital anoma...
Neuroendocrine tumors (NETs) originating from the gastrointestinal tract are considered to be relatively rare tumors with a poor prognosis. We describe a case of an 83-year-old male who presented with complains of bleeding per rectum. Colonoscopy revealed two ulceroproliferative tumors, one in the sigmoid colon and another in the descending colon. The patient underwent left hemicolectomy. Based...
BACKGROUND Celecoxib, a selective cyclooxygenase (COX)-2 inhibitor, has a pro-apoptotic effect on colon adenocarcinoma cells via COX-independent mechanisms. MATERIALS AND METHODS The pro-apoptotic effect of N-(2-Aminoethyl)-4-[5- (4-tolyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzenesulfonamide (TT101), a new derivative of celecoxib, was investigated on the HT-29 and SW480 colon adenocarcinom...
BACKGROUND Secondary tumours of the hyoid bone and thyroid cartilage are extremely rare. In this paper, we present a case of the hyoid bone and thyroid cartilage metastases in a patient treated for sigmoid colon adenocarcinoma. CASE REPORT Four years after sigmoid colon adenocarcinoma was diagnosed and treated with surgery and chemotherapy, the patient developed bone metastases in the left sa...
Colon interposition is an established technique for esophageal reconstruction. We describe the case of primary adenocarcinoma arising in a colonic interposition graft that was performed after total esophagectomy for recurrence adenocarcinoma derived from the Barrett esophagus.
BACKGROUND/AIMS The purpose of this study was to evaluate the clinicopathologic characteristics of colon cancers detected at the SOK Sokpeynhan Internal Medical Network, a nationwide system of primary health care institutions. METHODS We analyzed 579 colon cancer patients diagnosed using colonoscopy at the SOK network from January 2011 through December 2012. Cancers from the rectum to the spl...
Gelsolin, one of a major actin-binding proteins, is involved in the regulation of actin cytoskeleton organization by its severing and capping activity towards actin filaments. Human colon adenocarcinoma cell line LS180 and its selected variants of different metastatic potential were used to check for a correlation between gelsolin level, its subcellular localization and the invasive capacity of...
