Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional treatment and will have little effect on the prognosis of the individual. This article reports a synchronous rectal carcinoid in a patient with hepatic flexure adenocarcinoma...

PURPOSE: Recently, a different type of microsatellite instability (MSI) instability designated 'elevated microsatellite alterations at selected tetranucleotide repeats' (EMAST) has been reported in several neoplasms, but its clinical implications remain unclear. We aimed to determine the relationships among EMAST, MSI and clinicopathologic characteristics, including oncologic outcomes, in colorectal cancer (CRC). MATERIALS AND METHODS: We evaluated 100 sporadic CRC cases subjected to surgery using five markers (MYCL1, D9S242, D20S85, D8S321, and D20S82) for EMAST and the Bethesda panel for MSI status...

INTRODUCTION: Ano-rectal melanoma is an uncommon finding in patients complaining of rectal bleeding and/or anal mass often misinterpreted as a haemorroidal pile. CASE REPORT: A 55-years-old woman, complaining of rectal bleeding, frequent anal pain and anal mass suspected for haemorroidal thrombosis was referred for evaluation and possible treatment. A brown polypoid mass arising from the anal canal/lower rectum with a maximum diameter of 6 cm was diagnosed. The hystological examination of the neoplasm, transanally removed, revealed the presence of a polypoid melanoma partially involving the resection margin...

Radiation therapy represents an alternative treatment to radical prostatectomy in the management of clinically localized prostate cancer. Radiation-induced second neoplasms are defined by a latency period of at least 5 years, location within the field of radiation therapy, and a histology which differs from the primary tumor. Based on the data in the literature, there is a consistently increased risk of bladder cancer (HR: 1.67, 95% CI 1.55-1.80), rectal cancer (HR: 1.79, 95% CI 1.34-2.38), and colorectal cancer (HR: 1...

Anal cancer is uncommon neoplasm with an incidence of 2 new cases per 100,000 per year in the USA, accounting approximately 0.4 % of all tumors and 2.5 % of gastrointestinal malignancies. An early detection of the anal cancer is crucial for the patient management, whereas the diagnosis at an early stage allows conservative management with sphincter sparing, on the contrary a delays in diagnosis might lead to an advance cancer stage at presentation with worst survival. According to National Comprehensive Cancer Network (NCCN) Anal Carcinoma guidelines the patients should be subjected to a careful clinical examination, including a digital rectal examination (DRE), an anoscopic examination, and palpation of inguinal nodes...

Magnetic resonance imaging (MRI) plays now a major role in patients with colorectal cancer regarding tumor staging, surgical planning, therapeutic decision, assessment of tumor response to chemoradiotherapy and surveillance of rectal cancer, and detection and characterization of liver or peritoneal metastasis of colorectal cancers. Diffusion-weighted MRI (DW-MRI) is a functional imaging tool that is now part of the standard MRI protocol for the investigation of patients with colorectal cancer. DW-MRI reflects micro-displacements of water molecules in tissues and conveys high degrees of accuracy to discriminate between benign and malignant colorectal conditions...

We report a case of a 53-year-old woman who presented with rectal bleeding and a 9.5 cm hemicircumferential ascending colon mass. Histology revealed adenosquamous carcinoma (ASC), a rare subtype comprised of malignant squamous and glandular elements. Immunohistochemistry revealed loss of MLH1/PMS2 expression and retained MSH2/MSH6 expression in squamous and glandular components, indicative of microsatellite instability (MSI). MSI is caused by loss-of-function defects in DNA mismatch repair genes, leading to increased susceptibility to a variety of neoplasms; the role of MSI in colorectal ASC is unknown...

A 40-year-old woman visited our hospital with cyclic hematochezia for four months. The patient had the history of laparoscopic-assisted vaginal hysterectomy because of severe dysmenorrhea two years ago at another tertiary hospital. According to the medical records, the past surgical treatment was incomplete excision of pelvic endometriotic lesions, especially in rectal serosal lesions. A colonoscopy and abdominopelvic computed tomography showed an isolated tumor mimicking neoplasm, in which a biopsy under colonoscopy was performed and the lesion was endometriosis pathologically...

Syphilitic proctitis is a rare disease that usually presents as proctitis, ulcer, and neoplasm but lacks pathognomonic clinical symptoms. It is thus difficult to diagnose and may be treated inappropriately. We report a 31-year-old man who had a hard, ulcerated mass that occupied the rectal and sigmoid colon wall and mimicked a tumor. Fortunately, a biopsy of the mass demonstrated Treponema pallidum organisms consistent with syphilitic proctitis. The patient was successfully treated with intravenous benzyl penicillin, resulting in improvement in his proctitis...

Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the body's neuroendocrine system. Rectal high grade NEC (HG-NEC) constituting less than 1% of colorectal cancers can cause large ovarian metastasis that may be the initial presenting complaint. Ovarian Krukenberg tumor from a primary rectal HG-NEC is a very unusual and exceedingly uncommon differential diagnosis for secondary ovarian malignancy. This case report describes one such extremely rare case of a woman who had presented to the gynecology department with features suggestive of ovarian malignancy and was ultimately diagnosed to have Krukenberg tumor originating from neuroendocrine cancer of rectum...
