Caecal Perforation from Primary Intestinal Tuberculosis in Pregnancy

The classical picture of histopathology of the lymph nodes is a granulomatous lesion with caseous necrosis and numerous epitheloid cells, lymphocytes, plasma cells, and fibroblasts and Langerhans type of multinucleated giant cells.16 The two histological features which specifically point towards the diagnosis of tuberculosis are variation in the size of the granulomata and the presence of caseation necrosis. The histological differential diagnosis is granulomatous lymphadenitis due to sarcoidosis, foreign body granuloma or fungal infection which should be ruled out via appropriate diagnostic techniques.
