Aim: To present a patient with an uncommon primary extramedullary plasmocytoma in the colon. Case report: We report a case of a 64 year old female with wasting syndrome and low-gastrointestinal bleeding. Histology described colon and rectum with plasma cell infiltration in the muscle layer. The immunohis...
Colorectal cancer is the leading cause of malignancy of the gastrointestinal tract. A better understanding of the molecular and cellular changes that lead to the disease is necessary to develop early diagnosis and optimal treatment modalities. Rodent models are rapid, reproducible and exhibit an adenoma-...

OBJECTIVE: to report clinical and pathological features of patients with colorectal cancer diagnosed during emergency abdominal surgery. METHODS: records of 107 patients operated between 2006 and 2010 were reviewed. RESULTS: there were 58 women and 49 men with mean age of 59.8 years. The most frequent sy...
PURPOSE: To detect and quantify the immunoreactivity of TCF4 protein in colorectal carcinoma, colorectal adenoma and non-neoplasic colorectal epithelium. METHODS: We studied 129 individuals: 40 with colorectal cancer, 52 with colorectal adenoma and 37 with non-neoplastic colorectal epithelium. The colore...
INTRODUCTION: In Brazil, about 26,000 cases of colorectal cancer are diagnosed per year. Patients considered at the early stage of disease (without lymph node) evolve with tumor relapse or recurrence in up to a quarter of cases, probably due to understaging. Objective: Research on ex vivo sentinel lymph ...
INTRODUCTION: Despite the high prevalence and high rates of mortality of colorectal cancer, it is likely to be a secondary prevention disease due to the presentation of characteristics that are ideal for a successful screening program, with a proven positive impact on its outcome. OBJECTIVE: To describe ...
OBJECTIVE: Evaluate the appropriateness of colonoscopy indication for neoplastic lesion detection in patients under age 50 with hematochezia. METHODS: Retrospective and cross-sectional study in patients who underwent colonoscopy, from 2002 to 2009. Inclusion criteria included patients with hematochezia o...
