The youngest patient of lupus vulgaris; A cutaneous tuberculosis case report

Tuberculosis, which may involve most organs, is still a major health problem in developing countries. Despite a high and increasing frequency of tuberculosis, cutaneous tuberculosis (CT) is an uncommon form. CT may develop due to Mycobacterium tuberculosis, Mycobacterium bovis, and the Bacille Calmette-Guerin (BCG). CT may have various clinical forms. The most frequent form of CT is lupus vulgaris (LV). LV originates from inactive tuberculosis focus in the body and spreads by hematogenous or lymphatic way and by direct or exogenous inoculation. A diagnosis of LV was made based on clinical and histopathological examination. The lesions regressed after treatment with 3 antituberculous drugs. CT must be considered in cases with chronic skin lesions because tuberculosis prevalence is high in our country. Early diagnosis and treatment of patients with CT is extremely important in order to prevent complications. We report, to the best of our knowledge, the youngest CT affecting case.
