Tuberculous lymphadenitis
Introduction
Tuberculous lymphadenitis is a chronic specific granulomatous inflammation with caseation necrosis.
Histopathology: The characteristic morphological element is the tuberculous granuloma (caseating tubercule): giant multinucleated cells (Langerhans cells), surrounded by epithelioid cells aggregates, T cell lymphocytes and few fibroblasts. Granulomatous tubercules evolve to central caseous necrosis and tend to become confluent, replacing the lymphoid tissue. Photo at: Atlas of Pathology
