title: Ectoparasitic infestation of the lashes.
abstract: Phthirus pubis, commonly known as the crab louse, has as its habitat the pubic and inguinal regions of the body. Transfer between hosts is most commonly a result of sexual contact. On occasion, Phthirus pubis will leave its usual seat of predilection and infest other hair-bearing body parts. When infestation of the eyelashes occurs, it is known as phthiriasis palpebrarum. The case presented is an example of phthiriasis palpebrarum in a young female, apparently contracted as a result of transfer from the genital region of an affected male by hand contact.
