Lymphoid aggregate polyp.

Context: Lymphoid aggregates are seen in a minority of bone marrow biopsy specimens, and when present, their neoplastic nature is often apparent by morphologic evaluation. However, the distinction between benign and malignant aggregates can be a diagnostic challenge when there are multiple aggregates with no documented history of lymphoma.Submucosal lesions (lipomas, lymphoid aggregates, carcinoids, pneumatosis cystoides intestinalis) Adenomas and serrated polyps may be flat, sessile, or pedunculated (containing a stalk) Over 95% of cases of adenocarcinoma of the colon are believed to arise from these lesionsTubular adenomas are precancerous polyps in your colon typically found during colonoscopies.
