Primary linitis plastica of the right colon.
A case of primary linitis plastica of the colon is presented. This case is of interest for three reasons: the site of origin in the right colon (80% of cases reported develop distally to the splenic flexure), a biopsy previously taken from the mucosa demonstrated the presence of a signet ring cell carcinoma (endoscopic biopsies do not provide a conclusive diagnosis in the majority of cases reported) and hyaline with sparse amyloid nodules were detected in the extensive, dense fibrous tissue intermingled with tumour cells.
