The Utility of Dermoscopy for in vivo Detection and Treatment of Pediculosis Palpebrarum / 대한피부과학회지

Pthiriasis palpebrarum is a rare disease in which crab lice infest the eyelashes. It can cause pruritic lid margins, and it is difficult to diagnose and treat. We diagnosed and managed a case of pthiriasis palpebrarum in the right upper eyelid of a 35 month-old male child. We removed the lice and nits by pulling with fine forceps using dermoscopy. After treatment, all lice and nits had been eradicated without recurrence. We suggest that this is an effective, safe method for diagnosis and treatment of pthiriasis palpebrarum.

Mechanical Treatment of Phthiriasis Palpebrarum

Phthiriasis palpebrarum is a rare disease in which crab lice infest the eyelashes. It can cause pruritic lid margins or unusual blepharoconjunctivitis and is difficult to diagnose and treat. We diagnosed and managed a case of phthiriasis palpebrarum in both upper eyelids, accompanied by nits, on the scalp of a 6 year-old female child. We removed the eyelashes, including lice and nits, by pulling with fine forceps without sedation. On the second month after treatment, all lice and nits were eradicated without recurrence and the eyelashes grew back. In conclusion, phthiriasis palpebrarum can be diagnosed by close examination of the eyelashes and eyelid margins with slit lamp and can be managed mechanically.
