Varied presentation of tuberculosis adenopathy: an immunological and diagnostic contemplation

Tuberculous lymphadenitis is the most common presentation of extra pulmonary tuberculosis EPTB. Clinical and radiological presentation of disease may vary and differential diagnosis includes both benign and malignant conditions such as lymphomas and sarcoidosis. We present two case reports of tuberculous lymphadenitis with varied presentation. In case report Ⅰ, patient had undergone splenectomy due to traumatic splenic rupture had classical symptoms of tuberculosis, chest X-ray, CT thorax showed mediastinal and cervical lymphadenopathy. FNAC showed a picture of granulomatous lesion. In case report ⅠⅠ patient came with complaints of abdominal pain in hypochondriac region. CT and USG abdomen showed multiple enlarged retroperitoneal lymph nodes which led to a provisional diagnosis of lymphoma after which lymph node biopsy showed a granulomatous picture. This case report stresses the importance of early and quick diagnosis of tuberculosis in immunocompromised patients and highlights the risk of misdiagnosis of tuberculous lymphadenitis with other benign and malignant causes of lymphadenopathy and the importance of humoral mediated immunity in tuberculosis.
