MORAES, Aparecida Machado de et al. Perianal Bowen's disease treated with liquid nitrogen cryosurgery. An. Bras. Dermatol. [online]. 2002, vol.77, n.5, pp. 571-576. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962002000500007.
Bowen's disease is generally an asymptomatic in situ carcinoma that develops slowly. It rarely occurs in the genital region and mainly affects young persons. Skin lesions occurring in areas not exposed to sunlight may be associated with other factors, like HPV, inflammatory disease or colon neoplasia. The disease may be treated by conventional surgery, cryosurgery or photodynamic therapy. The aim is to present the clinical characteristics of a rare case of Bowen's disease in a young, black female, who had a large lesion in the perianal region, which tested positive for HPV. The woman had been undergoing treatment for intestinal ulcerative rectocolitis or Crohn's disease. She was treated with cryosurgery and there was no sign of recurrence during the ensuing 34 months.
