Lymphoid aggregate polyp.

The practical importance of finding a morphologically benign lymphoid aggregate in the bone marrow of patients without known lymphoproliferative disease was assessed in 786 consecutive patients who had had 951 iliac crest bone marrow biopsies performed. Of these, 430 patients known to have lymphoproliferative disease at the time of biopsy were ...1. Introduction. Lymphoid aggregates, whether benign or malignant, are a relatively uncommon finding in bone marrow biopsy specimens. In many cases, identifying the neoplastic nature of the aggregates by morphology can be easily achieved; however, in instances when multiple aggregates are identified with no documented history of lymphoma, such distinction may be difficult to achieve with ...Abstract. Lymphoid proliferations are traditionally thought to be either benign conditions (reactive hyperplasia and lymphadenitis) or malignant lymphomas. However, not all lymphoid lesions at present can be precisely placed into one of these categories.
