Treatment of Verruca Vulgaris in Both External Auditory Canals Using Bleomycin Injections

ABSTRACT

Verruca vulgaris is caused by human papillomavirus (HPV) infections. Verruca in the external auditory canal (EAC) has rarely been reported. A previous case report introduced surgical excision as a treatment for verruca in the EAC. We present a case of verruca vulgaris in both EACs that was successfully treated with an intralesional bleomycin injection. A 32-year-old male patient presented with ear fullness and palpable lumps in both EACs. Both of his canals were filled with multiple pinkish, papillomatous masses. Verruca vulgaris was confirmed by skin biopsy. An otolaryngologist referred this patient and recommended surgical excision. However, we performed intralesional bleomycin injections for treatment. Twice intralesional bleomycin injections at one-month intervals had excellent results without recurrence, ulceration or scar formation. This result indicates that bleomycin injections may prove to be an effective first-line treatment of verruca in the EAC.
