The superficial nature and the inclination toward diminutive lesions are characteristic of the eruption in the Negro. This type of lesion occurs independent of the nodular variety, but it is not unusual to see the two types occur coincidentally. Papulonecrotic tuberculid is not an entirely benign disease. While active tuberculous foci often remain obscure and complicating disease of other viscera is uncommon, still the incidence of tuberculous disease of vital organs
