Disseminated Tuberculosis in a Healthy Adolescent Female.

Disseminated tuberculosis (TB) is an uncommon sequela of Mycobacterium TB infection in which bacteria disseminate and form colonies outside of the lungs. Most reports of disseminated TB are found in immunocompromised patients, particularly in patients with human immunodeficiency virus (HIV) infection, malnutrition, genetic susceptibility, diabetes mellitus, smoking, and alcohol abuse. Few case reports describe the finding of disseminated TB in immunocompetent patients, especially in healthy adolescents. The purpose of this report is to present a case in which disseminated TB was found in an otherwise healthy adolescent, female patient, and to explore the effects of pubertal hormonal changes on the immune system. Several studies in the pediatric population have suggested that hormonal changes of estrogen and testosterone associated with puberty may influence the pathogenesis of active TB. While the exact pathogenesis of disseminated TB remains unknown, this case highlights the need for heightened awareness of TB among otherwise healthy adolescents, and specifically, the effect puberty has on disease progression.
