title: [A rare complication of ulcerative colitis: Bowen's disease in perianal condyloma acuminatum].
abstract: Discharging, itching perianal pointed condyloma acuminatum in a 35 years old male patient who had been suffering from ulcerative colitis for 20 years. Two years following its development the condyloma was excised. Histological examination revealed in the perianal condyloma in situ cancer, characteristic of Bowen's disease. With electronmicroscopic examination the tumor cells were found to be keratinocytes of medium differentiation. Virus could not be detected in the tumor cells. The author was the first to describe in the literature the development of perianal Bowen's disease on the ground of ulcerative colitis. On the basis of literary data the author emphasizes the importance of the radical removal and regular control.
