Scrofuloderma, also called tuberculosis cutis colliquativa, is a subacute form of cutaneous tuberculosis, which is characterized by subcutaneously-located, cold abscess formation and secondary changes of the overlying skin. Recently, the occurrence of cutaneous tuberculosis has decrease due to improved quality of life and development of effective anti-tuberculous drugs. However, the tendency of diminution of scrofuloderma has grown smaller because the number of old and immunocompromised patients has increased.
