The etiology of erythema nodosum. Kundratitz (Jahrb. f. Kindhlk., Bd. 63, H. 3—4)

Abstract

The 81 children observed by the author, aged from 12 months to 13 years, suffering from erythema nodosa, all reacted very strongly to tuberculin. Almost all had enlarged bronchial glands or the temporary darkening at the root of the lungs described by Ernberg; some had simultaneous frictions, lichen scrophulosorum or serous pleurisy. The author considers the nodular erythema a manifestation of the protective activity of the skin, in which the tbc bacilli circulating in the blood or their products are neutralized.
