Lymphoid aggregate polyp.

Tertiary lymphoid structures (TLS) are ectopic immune aggregates that form at sites of chronic inflammation such as cancer ( 1 ).

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.In addition to immunoreactivity, certain histological variables proved distinctive. These were: (1) histotopography, that is, localisation of the lymphoid aggregates within the bone marrow space; (2) relation to the surrounding tissue: margination or interstitial spillage of lymphoid cells; and (3) increase in reticulin fibres.Conventional endometrial, endocervical, or adenomyomatous pedunculated, or sessile lesion with histologic features diagnostic of polyp.
