Cutaneous Tuberculosis in a Child-Scrofuloderma

Cutaneous tuberculosis infection occurs world wide particularly in association with HIV infection malnutrition and poor sanitary condition. Scrofuloderma is a common type of tuberculosis characterized by a bluish red nodule overlying an infected lymph gland bone or joint that breaks down to form an undermined ulcer with a granulomatous tissue at the base. Progression of the disease leads to irregular adherent masses, densely fibrous at some places while fluctant and discharging at others. It heals with a characterstic puckered scarring at the site of infection. The disease is caused by mycobacterium tuberculosis and common antituberculous drugs are recommended for treatment.
