title: Perianal multiple Bowen's disease: a case report.
abstract: Bowen's disease, also known as an intraepithelial squamous cell neoplasia, is a carcinoma in situ firstly reported in 1912 by a dermatologist named Bowen from the United States [1]. About 3%~5% of Bowen's disease might develop into invasive squamous cell carcinomas of mocusa and skin [2]. Surgical resection is preferred because of its low recurrence. Here we reported a rare Bowen's disease case presented with multiple perianal lesions that were given surgical resection, but relapsed after 2 years.
