A white male student, 18 years of age, consulted us about alterations, which had been present for two months, in the color and form of the pubic hairs. The patient was concerned, not because of symptoms produced, but because he suspected that the changes possibly were of venereal origin.

On clinical examination, the hairs of the pubic region were found to be thickened and irregularly covered with solid concretions. These concretions, of variable dimensions, sometimes totally encircled the shaft of the hairs. They were very adherent and of a lusterless dark red color and could be removed from the hair with great difficulty. Some of the hairs presented an obvious division into two branches, presenting a trichoptilosis that had its initial point in one of these nodular concretions. The adjacent skin was not involved, and the hair of other regions of the body was not similarly involved.
