OBJECTIVE To show our results with the use of a polypropylene mesh at the stoma site, as prophylaxis of parastomal hernias in patients with rectal cancer when a terminal colostomy is performed. METHODS From January 2010 until March 2014, 45 consecutive patients with rectal cancer, underwent surgical treatment with the need of a terminal colostomy. A prophylactic mesh was placed in a sublay po...

BACKGROUND We report an unusual case of a synchronous rectal and metachronous vaginal metastatic renal cell carcinoma. CASE PRESENTATION A 78-year-old woman presented with hematochezia and a colonoscopy revealed a metastatic clear-cell renal cell carcinoma rectal polyp biopsy-proven. Abdominal computed tomography identified a 9.0-cm left renal mass with renal vein thrombosis, for which she un...

INTRODUCTION Muc~nous carcinoma is a subtype of adenocarcinoma containing abundant extracellular mucin within the tumor (1, 2). According to the WHO cnterla for mutinous carcinoma, the mucin composition should be at least 50% within the tumor for this diagnosis (1). Colorectal mutinous carcinomas tend to have been have lower curative resection rate and have an increased incidence of distant met...

BACKGROUND Locally advanced rectal carcinoma has a poor prognosis. However, since the introduction of preoperative radiotherapy, the outcome of patients with rectal carcinoma has been reported to have improved. Nevertheless, to the authors' knowledge few data are available regarding the histopathologic response to radiotherapy as assessed on surgical specimens as a potential predictive factor f...

Non-motile cilia are thought to be important determinants of the progression of many types of cancers. Our goal was to identify patterns of cilia gene dysregulation in eight cancer types (glioblastoma multiforme, colon adenocarcinoma, breast adenocarcinoma, kidney renal clear cell carcinoma, lung squamous cell carcinoma, lung adenocarcinoma, rectal adenocarcinoma, and ovarian cancer) profiled b...

BACKGROUND The most common type of carcinoma associated with ulcerative colitis (UC) is adenocarcinoma. We present a case of primary rectal small cell carcinoma in a patient with a history of UC. METHODS A 34-year-old male diagnosed with UC for 10 years was not consistent with the usual annual follow-up and presented with mucoid-bloody diarrhea. Colonoscopy revealed a rectal mass 2 cm distant...

BACKGROUND Prostate cancer involving the rectal wall is rare and may lead to diagnostic pitfalls. CASE PRESENTATION Out of 9504 patients with rectal tumors between January 2003 and January 2015, 9 patients (elderly with a mean age of 74 years) with prostate cancer involving the rectal wall were clinically misdiagnosed with rectal cancer. The lesions were located in the rectum, and included 3 ...

Rectal varices most commonly develop in patients with portal hypertension due to liver cirrhosis. Although rectal varices rarely cause bleeding, their rupture can lead to life-threatening massive hemorrhages. Balloonoccluded retrograde obliteration (BRTO) is feasible in cases of varices involving a single or a few drainage vessels. Although rectal varices usually have numerous drainage vessels,...

A case is presented of rectal carcinoma in which during staging by endoscopic ultrasound (EUS) a second large extrarectal mass was seen not otherwise visualized on computer tomography (CT) that was a solitary ovarian metastasis. The surgeon was alerted to the EUS finding prior to the planned laparoscopic colectomy. On retrospective review of the CT pelvis after surgery, the radiologist could st...
