[Perianal Buschke-Löwenstein tumour].

The Buschke-Löwenstein tumour is an extremely rare, slow-growing cauliflower-like mass, also known as giant condyloma acuminantum or verrucous carcinoma. It is located in the anogenital region and is characterized by its large size, locally destructive behaviour and a high recurrence rate. It has not the potentiel to metastasize but malignant transformation can occur. We report a case of a 49-year-old male patient with a 17 × 10 cm large perianal Buschke-Löwenstein tumour where histologic findings showed the presence of verrucous carcinoma.
