[Endoscopic and echoendoscopic findings in secondary linitis plastica of the rectum]. / Hallazgos endoscópicos y ecoendoscópicos en la linitis plástica rectal secundaria.

ABSTRACT

Linitis plastica of the rectum consists of intraparietal, subepithelial and circumferential tumoral infiltration of the wall of the rectum leading to a constricted rectum with mural thickening. There is often a delay between symptom onset and diagnosis because this entity mimics a large number of diseases and the findings of endoscopy and conventional biopsies are non-conclusive since the surface mucosa is not usually affected. We present the endoscopic and echoendoscopic findings of two patients with secondary linitis plastica of the rectum.
