Scrofuloderma: a common type of cutaneous tuberculosis. A case report

ABSTRACT

Scrofuloderma is a common type of cutaneous 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 granulating tissue at the base. Progression of the disease leads to irregular adherent masses, densely fibrous at some places while fluctuant and discharging at others. It heals with a characteristic puckered scarring at the site of infection. The disease is caused by Mycobacterium tuberculosis and common anti-tuberculous drugs are recommended for treatment. Many similar cases with additional features have been reported in foreign literature. We describe a case of this disorder along with review of literature
