Unusual Presentations of Extrapulmonary Tuberculosis in Three Hemodialysis Patients

Abstract

We report three patients who received maintenance hemodialysis and suffered from extrapulmonary tuberculosis with unusual presentations. The first patient presented with fever of unknown origin. All studies showed negative findings except high erythrocyte sedimentation rate and high value of C-reactive protein. He failed to response to broad-spectrum antibiotics but showed a complete response to antituberculosis therapy. The second patient presented with right supraclavicular lymphadenopathy and weakness. Lymph node biopsy revealed caseating granuloma with positive acid-fast bacilli. The third patient presented with tumor mass of left sternoclavicular joint for which malignancy was suspected initially. Ultimately, tuberculosis was documented by histopathologic studies showing caseating granuloma. All three patients had normal findings of chest x-ray and did not have previous history of tuberculosis and diabetes mellitus.
