A Cases of Bowen's Disease Arising in an Old Burn Scar

It is known that Bowen's disease is a representative precancerous lesion of squamous cell carcinoma, along with actinic keratosis. Chronic sun-exposure and arsenism are main causes of Bowen's disease. Also trauma, radiation, and viral infection are associated. Up to now, it is not yet reported that bum scar can induce Bowen's disease. We report an unusual case of Bowen s disease, which arose in an old bum scar. (Korean J Dermatol 2004;42(5):640-642)
