A pediculid case: autosensitization dermatitis caused by pediculosis capitis.

Pediculosis capitis is a worldwide infestation caused by Pediculus humanus capitis ectoparasite that only lives on the hairs of the scalp. As a result of severe itching excoriation, secondary bacterial infection, cervical and occipital lymphadenopathy are seen frequently where, sometimes bite reaction, viral exanthema mimicking hypersensitivity eruption and conjunctivitis may occur. Hereby, with the presentation of a quite rarely seen pediculid case, characterized with common autosensitization dermatitis as an -id reaction to pediculosis capitis, the importance of exploring the source of the infection and/or infestation on the patients who have presented with generalized pruritic maculopapular eruption, is emphasized.
