Ectoparasitic infestation of the lashes.
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.
