Cutaneous Bowen's Disease: an Analysis of 182 Cases according To Age, Sex, and Anatomical Site from an Italian Center

Bowen's disease (BD), also known as squamous cell carcinoma in situ, is a type of non-melanocytic intraepidermal malignancy characterised by a slowly enlarging erythematous to pink, scaly patch or plaque with irregular and well-demarcated borders. These lesions are usually persistent and progressive; it has been estimated that in general population around 3% to 5% of Bowen's disease transform into invasive squamous cell carcinoma. This report describes our experience with cutaneous BD and assesses the differences found about age, sex and anatomical site. Bowen's disease was seen more frequently in male patients rather than in female patients in contrast to what confirmed in literature - this difference is probably because being head-neck an exposed region, patients are more easily induced to autoexam and to consult the dermatologist.
