Tuberculosis (TB) is the main cause of infection-related death in the world. Children make up ∼5-15% of all TB cases. Severe forms of disease such as meningitis and disseminated form are more common in children. Due to current estimates of World Health Organization (WHO) in 2015, one million children suffer from TB around the world; of these, it is estimated that more than 136,000 die a year. One study estimated 67million children with latent TB which develops to active form with the rate of ∼850,000 each year...

Tuberculosis remains one of the leading causes of death around the world despite advancements in diagnostic testing and medical therapies. It commonly affects the lungs, but isolated extra pulmonary clinical manifestations have been reported. Tuberculosis of the oral cavity is exceedingly rare. We present a case of a patient with dermatomyositis on chronic steroid therapy, who presented with tuberculosis involving the tongue as the only clinical manifestation of disseminated disease. Physicians must be aware of extra pulmonary manifestations of tuberculosis in patients at risk, in order to avoid delays in diagnosis and treatment and to prevent further contagion...
