PLI'CA, n. [L. a fold.]

Trichosis plica is a disease of the hair, peculiar to Poland and the neighboring countries. In this disease, the hair of the head is vascularly thickened, matted or harled by means of a glutinous fluid secreted from its root. It sometimes, but rarely, affects the beard, the hair of the pudenda, and of the rest of the surface of the body. It seems to prevail in Poland as an endemic disease.
