Role of endoscopic ultrasound guided fine needle aspiration/biopsy in the evaluation of intra-abdominal lymphadenopathy due to tuberculosis

Figure 1 Histopathology findings on the fine needle aspiration sample of a patient with tuberculosis. A: An epithelioid cell granuloma with scattered lymphocytes and red blood cells in the background (100 ×); B: Collection of epithelioid histiocytes forming a granuloma (400 ×); C: Necrotic material and inflammatory cells (400 ×).
