Circumferential resection margin (CRM) appears as a new powerful prognostic factor of survival after surgery for rectal cancer. We aimed to evaluate predictive factors of positive CRM following preoperative radiochemotherapy in a French trial. Patients with rectal cancer were randomised in long course preoperative radiotherapy 45 Gy plus capecitabine versus 50 Gy plus capecitabine and oxaliplatin.

Background And Aims: Management of patients with endoscopically removed colorectal polyps is generally dependent on pathological evaluation. The aim of this study was to assess the accuracy and clinical impact of pathologic interpretation of colorectal polyps by community pathologists.
Methods: Two expert gastrointestinal pathologists reviewed the slides of 300 colorectal polyps initially examined by 14 general pathologists.
Objectives: To evaluate the role of a cytopathologist expert in interpreting difficult pancreatic endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in terms of impact on diagnostic yield and therapy in current clinical practice.
Methods: Retrospective study of 106 EUS-FNA performed between January 2002 and September 2004. Forty-seven cases of difficult interpretation by the local cytopathologist were mailed to an expert cytopathologist.
Introduction: Histological examination of a biopsy of a lesion of the glans penis revealed blood capillaries within the malpighian epithelium.
Case Report: A 66 year-old man exhibited two circumscribed red plaques of the glans penis following posthectomy. Their histological examination revealed blood capillaries within the epithelium without basal membrane and pericytes between the endothelial cells and keratinocytes.
