Retroauricular bowen's disease of skin in an elderly female

Sir, Bowen’s disease is an intraepidermal squamous cell carcinoma (SCC), also termed as carcinoma in situ. It usually occurs in 6th–8th decades of life, predominantly in the head-and-neck area.[1] It presents as well-defined gradually progressing erythematous patches or plaques with scaly or crusted surface.[2] Early diagnosis and treatment are required as it has the risk of progression to invasive SCC. We herewith report a case of retroauricular Bowen’s disease considering the rarity of the site being involved and to depict the successful therapeutic response to 5-fluorouracil (5-FU) cream.
