Organ transplant recipients are at the increased risk of infection complications. Herein, we present a case of unusual localisation of tuberculosis in renal allograft recipient treated by combination of cyclosporine A, mycophenolate mofetil and steroids. After the non specific prodromes, surgery due to ileus discovered ileocaecal tumour. Microscopically tuberculosis inflammatory process with ulcerations of the intestinal mucosa and caseification of the lymphatic nodes, instead of the expected lymphoma was proved to be present. We are discussing the incidence of tuberculosis in relation to immunosuppressive therapy as well as possible pathways of tuberculosis transmission.
