Abstract:
Methotrexate (MTX) may have adverse effects on multiple organs and system. A few cases of pulmonary tuberculosis in-patients with rheumatoid arthritis (RA) while receiving MTX monotherapy has been reported in the literature. We submit a case of vertebral tuberculosis with hypercalcemia in a patient receiving MTX monotherapy. Patient with RA taking MTX for 15 years developed pancytopenia, skin necrosis, tuberculous spondylodiscitis and hypercalcemia. The present case showed adverse effects of MTX therapy may occur even after years of continuous treatment. Due to pancytopenia in older patients, life-threatening tuberculosis at unusual sites may develop.
