Abdominal tuberculosis mimicking Crohn's disease: a difficult diagnosis. Report of a case.

Abdominal involvement by tuberculosis as first site of disease is comparatively rare in industrialized countries. The emergence of new groups of patients at risk arouse a particular and due interest. This report describes a case of abdominal tuberculosis with a first diagnosis of Crohn's disease in an immigrant girl from Peru. The diagnosis can be difficult because extrapulmonary tuberculosis is often paucibacillary and the disease may mimic a variety of gastrointestinal disorders.
