Bowen Disease over photoprotected site in an Indian male.

Bowen Disease is squamous cell carcinoma in situ in which the basement membrane is intact on histopathology. Lesions are usually solitary but may be multiple in 10-20 percent of cases. About three-quarters of these lesions are situated on the lower limb. It typically presents as an erythematous enlarging plaque having irregular borders with scaling and crusting. Our patient presented with a lesion on the chest that was not sun exposed thus leading to a diagnostic dilemma.
