Rarely, colorectal adenomas involve submucosal LGCs, simulating invasive adenocarcinoma with associated submucosal lymphoid aggregates, and presenting a diagnostic pitfall.Although these lesions typically lack lymphoid aggregates, they can be present adjacent to foci of misplaced epithelium in approximately one-third of cases. Polypoid colonic hamartomatous inverted polyp is a benign lesion of the rectum, due to an inverted or downward growth of mucosal glands through the muscularis mucosa into the submucosa.

In addition, we examined 40 cases of bone marrow biopsies with documented malignant lymphoid aggregates for comparison purposes.Intramucosal lipomas are rare and easily overlooked by pathologists, despite their diagnostic significance for Cowden syndrome (PTEN hamartoma tumor syndrome), an inherited multiorgan cancer syndrome. Only 25-35% of patients harbor identifiable PTEN mutations, thus clinical features, like intramucosal lipomas, remain the mainstay of diagnosis.
