Different clinical form of tuberculosis in childhood: Three cases

Childhood tuberculosis (Tbc) is an important cause of morbidity and mortality and the highest case burden, an estimated 95% of all Tbc cases is found in developing countries. Although childhood Tbc contributes to only 3-6% of the total caseload in industrialized countries, it makes up a large proportion (15-20%) of all Tbc cases in developing countries. The diagnosis of tuberculosis in children is quite difficult and seldom confirmed and is based mainly on clinical signs, symptoms, history of contact with adult and special investigations. Tbc in children, which is paucibacillary in nature, is usually smear-negative. Bacteriological confirmation by culture of Mycobacterium tuberculosis the gold standard of diagnosis, but rarely exceeds 30-40%. In this writing, we report three different cases those are diagnosed as a Tbc and treated.
