Psorospermosis

Psorospermosis may be defined as a condition of the skin of varied lesion, but characterized by the presence of "psorosperms". The psorosperm is a living animal parasite, which infests the human skin as well as the bodies of some of the lower animals, and consists of a roundish or oval cell, containing one or more nuclei, the nucleus occupying but a small portion of the cell, the plasmic portion of which is extremely transparent and structureless.

Much doubt exists among dermatologists as to the nature of this affection; and but little is known positively concerning it.
