CONTEXT: Infection is a common cause of lymphadenopathy in @entity1 and has numerous microbial etiologies. Lymph node biopsy is considered a keystone in arriving at a definite diagnosis. An accurate differential diagnosis from a lymph node biopsy can expedite diagnosis and minimize ancillary testing. OBJECTIVE: To assess and compare the histopathologic and epidemiologic features of common and uncommon pediatric bacterial @entity3298 . DESIGN: We searched our database for surgical specimens that had a positive identification of bacteria during an 8-year period. The chart was reviewed to assess the pathogen identified and epidemiologic data. The archival tissue sections were reviewed and the histopathologic findings described for each pathogen. RESULTS: The review of 368 pediatric lymph node biopsies identified 33 cases with a @entity2348 . These comprised 21 cases of @entity3069 complex (60%), 1 of @entity3069 fortuitum (3%), 7 of @entity2711 (20%), 2 of @entity2820 (7%), 1 of @entity5092 (3%) and 1 of @entity4195 (3%). CONCLUSIONS: Each of these infectious lymphadenitides had distinct epidemiologic and histopathologic features that are discussed in this report.
