CONDYLOMA ACUMINATUM OF THE BLADDER IN TWO AUTOPSY CASES

Abstract

Condyloma acuminatum is a very rare lesion occurring in the bladder. We report two cases of condyloma acuminatum of the bladder found at autopsy, one in a 96-year-old woman and the other in an 80-year-old man. Both had papillary or polypoid tumorous lesions in the trigone and neck of the bladder. The lesions were composed of nodular or papillary growths of squamous epithelium. The epithelium exhibited koilocytosis and the nuclei showed immunohistochemical staining for human papillomavirus antigen.
