[Tetralogy of Fallot, congenital coronary aneurysms with the histology of periarteritis nodosa: nosologic problems].

Coronary lesions of periarteritis nodosa are detected in a newborn suffering from a Fallot's tetrad. The authors remind us of the present concept of infantile P.A.N. similar to adults' and of the notion of Kawasaki's syndrom that is almost the same as the infant's serious P.A.N. The reported case, original in many a detail, seems to represent the later expression monosymptomatic of Kawasaki's syndrom as if this one had been amputated at that stage of the greater part of its elements and then, casually developed in utero upon a congenital cardiopathy.
