  Outcome Measures

1.  Primary:   Proportion of Patients With Regression of Perianal High-grade Squamous Intraepithelial Lesions (HSIL)   [ Time Frame: 6 weeks after treatment discontinuation ]

2.  Primary:   Safety and Tolerability of Topical Cidofovir as Assessed by NCI CTCAE v3.0   [ Time Frame: Every 2 weeks on study, 6 weeks after treatment discontinuation ]

3.  Secondary:   Human Papilloma Virus (HPV) DNA Type in Perianal HSIL and Normal Perianal Tissue   [ Time Frame: Baseline ]

4.  Secondary:   Correlation of Clinical Regression of Perianal HSIL With Clearance of HPV DNA   [ Time Frame: 6 weeks after treatment discontinuation ]

5.  Secondary:   Identification of HPV-DNA Types Present in the Anus   [ Time Frame: Baseline ]

6.  Secondary:   Identification of Abnormally Methylated Genes in Perianal Dysplasia   [ Time Frame: Baseline, after cycle 1, and 6 weeks after treatment discontinuation ]

7.  Secondary:   Distribution of Abnormally Methylated Genes Among HSIL, Low-grade Squamous Intraepithelial Lesions, and Normal Perianal Skin   [ Time Frame: Baseline, after cycle 1, and 6 weeks after treatment discontinuation ]

8.  Secondary:   Changes in Gene Expression in Perianal HSIL After Exposure to Cidofovir as Assessed by RNA Microarray Analysis   [ Time Frame: Baseline, after cycle 1, and 6 weeks after treatment discontinuation ]
