title: Anorectal giant condyloma acuminatum (Buschke-Loewenstein tumor): CT and radiographic manifestations.
abstract: Giant condyloma acuminatum (Buschke-Loewenstein tumor) is an unusual variety of venereal wart characterized by a large size, cauliflower-like appearance, and locally invasive nature. CT examination of two patients with anorectal giant condylomata revealed the papillomatous and invasive nature of the lesion and the extent of tumor; there was infiltration of the subcutaneous tissue, perirectal fascial planes, and luminal narrowing with marked thickening of the rectal wall. The pathologic specimens showed benign histologic findings in one case and a mixed pattern with areas of malignant degeneration in the other. CT accurately demonstrated the exact location and extent of the lesions. The presence of malignant degeneration in this inherently invasive lesion can be established only on histologic examination.
