Özet:

Pseudolipomatosis coli is an iatrogenic entity due to the endoscopic procedures which has an unclear pathogenesis. Mucosal damage, gas invasion or lymph extravasation caused by barotraumas resulting from endoscopic procedures or the effect of the colonoscopic disenfection products could be blamed in the pathogenesis. The terminology "pseudolipomatosis" has been used because of the similarity to the lipomatous tissue macroscopically and microscopically. Pseudolipomatosis can be observed in different parts of the gastrointestinal system from stomach to rectum and named as pseudolipomatosis coli when the entity is located in the colon like it is in the presented case. Histologically numerous cytics spaces with no epithelium are seen in the mucosa especially in the lamina propria. The case was presented as an entity in the differential diagnosis to keep in mind that it is important to avoid unnecessary treatment during the evaluation of endoscopic biopsies.
