, or pityriasis rubra pilaris as it is called by many writers, is a rare disease, but one which is liable to affect children as well as adults. It is a chronic and obstinate disease, in which the lesions are small, reddish, acuminate papules,



usually seated at the orifice of hair follicles. These do not increase in size, but by multiplying and coalescing produce patches covered by fine, whitish scales and characterized by an exaggeration of the natural furrows of the skin.
