[Verrucous carcinoma of the anal margin. The Buschke-Loewenstein tumor]

The Buschke-Loewenstein tumour is a rare variety of squamous cell carcinoma of low-grade malignancy; it is located in the external genital organs and the perianal region. We present a new case of this uncommon tumour of short evolution in a 73 years old male patient. Resection was the only treatment, without relapse at 12 months. A review of the literature shows only 13 cases previously published; we comment the human papillomavirus role in their pathogenesis and the various therapies proposed, concluding that the best is surgical treatment.
