[COLONIC MUCO-SUBMUCOSAL ELONGATED POLYP: A CASE REPORT AND LITERATURE REVIEW]. / IZDUZENI SLUZNICNO-PODSLUZNICNI POLIP DEBELOG CRIJEVA: PRIKAZ BOLESNIKA I PREGLED LITERATURE.

Recently a new entity has been described--a colonic muco-submucosal elongated polyp (CMSEP)--that did not fall into traditional classification of colorectal polyps. The CMSEP is endoscopically characterised by elongated, worm-like appearance with a normal overlying mucosa. Histologic characteristics of the CMSEP comprise mucosa and expanded submucosa with dilated vasculature and lymphatics. Herein, we report a case of CMSEP, that to the best of our knowledge, has not been previously described in our literature. With regard to the on-going National colorectal cancer screening programme, our intention is to draw attention of gastrointestinal pathologists and endoscopists to this distinctive and very rare phenomenon.
