title: [Pyoderma gangrenosum and haemopathy. Report of three cases (author's transl)].
abstract: The authors report three personal cases of phagedenic pyoderma associated with hemopathy. Studying twenty-five other cases, described in the reviews, the question can be debated on three levels: 1) The clinical characteristics of hemopathic pyoderma remain non-specific. However blisters, pustules, and even vegetating lesions occur very often; 2) the etiology of hemopathy is subject to change; acute leukaemia or myeloproliferation syndrome. During the polyglobulars associated with pyoderma, anemia and myelofibrosis appear quite constantly; 3) finally on the pathogenic level, the recent works tend towards the hypothesis of a damage in the functioning of the polymorphonuclears hence displaying the increase in the inflammation during phagedenic pyoderma.
