Eosinophilic folliculitis in a Caucasian patient: association with toxocariasis?


Sterile eosinophilic folliculitis, a clinical entity first described by Ofuji in 1970, is a rather rare skin disorder, in particular in the non-Asian population. We report the first case of eosinophilic folliculitis associated with toxocariasis in a Caucasian patient. Topical and systemic anti-inflammatory and antiphlogistic therapy along with systemic antihelminthic treatment resulted in complete remission of the skin lesions. In addition, there was a marked decrease of antibodies to Toxocara antigens in the patient's serum following antihelminthic therapy. Given that (I) some cases of eosinophilic folliculitis have been reported which were associated with infestation with metazoan parasites; (2) infestations with the roundworm Toxocara canis are known to induce eosinophilic reactions in some tissues; and (3) therapy-induced remission of eosinophilic folliculitis was accompanied by a decrease of Toxocara-directed antibodies in the patient's serum, we propose that there is an aetiopathogenic link between toxocariasis and eosinophilic folliculitis in this patient.
