Abstract

SOME PECULIARITIES OF THE CLINICAL ASPECT OF PITYRIASIS ROSEA

Pityriasis rosea was first described in 1860 by the French author Gibert and represented as a morbid entity sui generis. This universally recognized dermatosis has retained its morphologic independence up to the present time. Only in the course of the following decades was the classic clinical description of Gibert amplified by the addition of some more or less essential features. As such a feature I must first designate the "plaque primitive" (initial plaque) described by Brocq in 1887. Attention has been called, particularly by English scientists, to the fact that pityriasis rosea not only manifests itself by typical lesions of delicate pink, oblong-ovoid in shape and with central desquamation, arranged along the lines of skin cleavage, but may be characterized by primary lesions of another kind. Thus Pringle, Little. Adamson and others have observed the vesicular type of the eruption.
