The paper reports the case of a 39-year-old woman evaluated for intermittent diarrhea after stopping contraceptives, in whom colonoscopy showed a protruding lesion in the sigmoid region with intensely edematous and reddened mucosa, leading to invagination and relative lumen stenosis. Biopsies were compatible with intestinal endometriosis, which the authors describe as an infrequent entity with a prevalence of 3–37% and a highly variable presentation; they note that common colonoscopic findings include eccentric mucosal thickening and possibly nodular, polypoid-appearing mucosa. The paper’s explicit limitation is that definitive diagnosis relies on anatomopathological study, emphasizing biopsy for confirmation. This paper is centrally about endometriosis — specifically a case report of intestinal endometriosis diagnosed via colonoscopy and biopsy.

Abstract

Abstract Text A 39-year-old woman who is studied for intermittent diarrhea since discontinuation of contraceptives. In the study, colonoscopy is performed, at the level of the sigma, a protruding lesion with intensely edematous and reddened mucosa is observed, although the pattern with light filters is apparently normal, which conditions an invagination and a relative stenosis of the lumen. Biopsies are taken, compatible with intestinal endometriosis. Intestinal endometriosis is an infrequent entity with a prevalence of 3-37% with a very variable clinical presentation. The most common finding in colonoscopy is the eccentric thickening of the mucosa, and nodular mucosa with a polypoid appearance can also be found. For the definitive diagnosis, anatomopathological study will be important, so it is important to take biopsies of the lesion. [1]
