title: [Post-traumatic nodular scleroderma].
abstract: Scleroderma of rare appearance in children appears in minor scale as to the five per cent on the whole incidence of this collagen disease. The children usually present localized scleroderma and at times associated with other pathologies, traumatisms and injections were referred. Two patients aged 5 and 13 years old are presented, both with nodular lesions on anterolateral thigh area, and in the right buttock respectively. The patches of a side bigger than the palm of hand were only touchable and the skin that covered them only showed a slight hyperpigmentation in the edge in one of the cases. The limits were not precise and the nodulose surface was irregular. The evolution was as of two and three years, right after inoculation of antitetanical vaccination and puncture thorn of Yuca leaves. The histological control showed intensive phenomenons of fibrohyalinosis covering almost all the dermis. The studies of the laboratories didn't produce interesting data. The histological and clinical set of symptoms shows differences with the esclerodermic like states as a consequence of excipient of vitamin K, B 12, norhydroxprogesterone and anti-tetanic serum, in which they settle in the cellular subcutaneous tissue and they involution spontaneously. There are also differences with the paniculitis artefacta and with the lincar morphea associated to bifid spine. At last the authors make special mention of the case described by Desmons of progressive linear scleroderma right after the triple vaccination. The nodular or subcutaneous scleroderma is a clinical form in which the histological alteration decays in deep dermis and superficial hypodermis. The cases shown suggest a conection between a previous traumatism and the nodular scleroderma.
