title: Is endoscopic resection a correct treatment for atypical gastrointestinal lipomas?
abstract: We would like offering our experience about a very rare and underestimated type of gastrointestinal lipoma, which is the lipoma with precancerous or frankly malignant features of the mucosal epithelium, the so-called atypical lipoma. So far, only few cases have been described in the world literature. Recently, we grappled with what we think the first case of atypical colonic lipoma presenting with adenocarcinomatous transformation of the overlying epithelium, as discussed in more detail below. We propose a new definition and classification for this kind of lesions and discuss about their diagnosis, treatment and prognosis.
