[Skin manifestations of Still's disease in adults. Apropos of 4 cases].
The authors report four new cases of Still's disease in adult. Each time, the clinical picture associated the following triad: fever, joint involvement and skin rashes. The latter consisted in non-pruritic but sensitive maculo-papular and disseminated lesions, the mean course of which lasted 24 to 48 hours and were readily accompanied by the two other components of the basic clinical triad. Laboratory investigations were non-specific but constantly included a polymorphonuclear leucocytosis and a raised ESR, the mean value of which reached 80 mm in the 1st hour. Antinuclear factors were not demonstrated, but circulating immune complexes were found on several occasions in three out of the four reported cases. Histopathological changes observed were those of a superficial and mid cutis edema, associated with a diffuse or perivascular infiltrate in which either mononuclears or polymorphonuclears were prominent. Dermal vessels involvement appeared rather weak, including swelling of the walls by edema with focal fibrinoid necrosis. Direct immunofluorescence showed mainly IgG, IgA and C3 vascular deposits. Based on these data, an immune pathology is discussed, besides the more classic infections pathogenesis.
