Large Cecal Lipoma With Overlying Ulceration Simulating Malignancy: A Case Report and Review of Relevant Literature

“…The true etiology of gastrointestinal lipomas is still not clearly understood [28,29]. Colonic lipomas originate from the sub mucosa and protrude into the gastrointestinal lumen.…”

“…Endoscopic ultrasonography (EUS) is a very effective modality for characterizing submucosal tumors because it identifies the layer of origin of the submucosal lesion. The five-layer structure of the colorectal wall seen on endoscopic ultrasonography corresponds to the histologic appearance [29]. Colonic lipomas appear as hyperechoic homogeneous masses arising from the third layer on endoscopic ultrasonography [30,31].…”

“…Colonic lipomas appear as hyperechoic homogeneous masses arising from the third layer on endoscopic ultrasonography [30,31]. This characteristic appearance can be used to differentiate lipomas from lymphangioma, smooth muscle tumors, and metastatic malignancies [29]. EUS can also be used as a tool to determine any extension into the muscularis propria before injection-assisted polypectomy of symptomatic lipomas [30].…”

“…This will lead to the creation of a space with a subsequent adipose tissue deposition. These are better termed as pseudo-lipomas [5] .…”
