title: Squamous cell carcinoma arising in a giant condyloma acuminatum (Buschke-Lowenstein tumour).
abstract: Giant condyloma acuminatum (GCA) is a tumour that primarily affects the genital and perianal areas. Despite the histologically benign appearance, it behaves in a malignant fashion, destroying adjacent tissues, and is regarded as an entity intermediate between an ordinary condyloma acuminatum and squamous cell carcinoma. Primary anorectal lesions account for only a small number of GCA cases and, as with squamous cell carcinoma, the human papilloma virus is the causative agent. The hallmark of GCA is the high rate of local recurrence and transformation into squamous cell carcinoma. We describe a case of GCA complicated by malignant transformation, where locoregional control was achieved with combined chemoradiotherapy.
