Tuberculous peritonitis in an adolescent male

Tuberculosis (TB) is a less common disease in adolescents than in any other age group. However, when it occurs it is extrapulmonary 10% of the time. We report a case of TB peritonitis in an adolescent patient who presented without a history of prior TB or TB exposure. Tuberculosis must be included in the differential diagnosis of any occult febrile illness, even in the absence of pulmonary disease.
