title: [Extrapulmonary tuberculosis. An important differential diagnosis in immigrants with suspected malignancy].
abstract: The incidence of tuberculous disease is increasing all over the world, mostly in the poor, developing countries, but also in some industrialized countries. In Norway, extrapulmonary tuberculosis is a rare phenomenon. It is found mostly among older Norwegians and in younger immigrants from the third world. Since the disease is rare, it may be overlooked or confused with malignant disease. We describe two patients with unusual forms of extrapulmonary tuberculosis, both mimicking neoplastic disease. The first patient was a 27-year-old woman from South-East Asia, who was operated on for suspected intraductal comedo-type carcinoma of the breast, but histological examination showed tuberculous mastitis. The second patient was a 26-year-old man from East Africa with a medical history indicating intra-abdominal lymphoma. The final diagnosis, however, was mesenteric tuberculous lymphadenitis. Both patients were treated successfully with isoniazid, rifampicin and pyrazinamide.
