Background: Lymph node status is an important prognostic factor in the staging of colorectal carcinoma. Several adjunctive solutions have been used to increase the yield of pericolic lymph nodes from colorectal cancer resection specimens.
Methods: During 1998 at the Grey Bruce Regional Health Centre (Owen Sound, Ontario), 67 colonic resections were performed for colorectal cancer.

Aims: Basaloid carcinomas typically arise in the anal canal and there are only three well-documented cases of this neoplasm reported outside the anal canal, none more proximally than the sigmoid colon. The first occurrence of a basaloid colonic carcinoma arising outside the sigmoid colon, at the splenic flexure, is presented.
Methods And Results: A splenic flexure mass was resected from a 54-year-old man with a 3-week history of abdominal discomfort, diarrhoea and weight loss.

Cytohistologic correlation was performed by 3 observers on 100 atypical squamous cells of undetermined significance (ASCUS) cases from a colposcopy clinic. Our objectives were to: 1) subclassify ASCUS cases and determine their clinical significance; 2) assess the independent predictive value of different cytologic parameters for biopsy-proven dysplasia (BPD); and 3) calculate interobserver variability. The prevalence of BPD was 73% in the ASCUS favor dysplasia (AFD) group, and 27% in the ASCUS favor reactive (AFR) group (P 0.

Evidence is emerging that sodium phosphate (NaP), a commonly used oral cathartic agent, causes aphthoid ulcers or focal active colitis (FAC) in the colon and rectum. The aims of this study were (1) to assess the incidence of such ulcers diagnosed endoscopically ("aphthoid ulcers"), (2) to assess the incidence of histologically detected FAC and neutrophilic infiltration overlying lymphoid follicles ("aphthoid lesions"), and (3) to determine whether this effect of NaP is associated with epithelial cell proliferation. Aphthoid ulcers, unexplained by other diagnoses, were found in 18 of 687 consecutive patients (2.
