Bowen’s disease is a clinical expression of squamous cell carcinoma in situ of the skin which presents as an asymptomatic well defined erythematous scaly plaque. (Weedon’s skin pathology, 2010) There is a predilection for both sun exposed areas like head and neck and non sun exposed areas like genitalia of both sexes, occurring in elderly people. A case of Bowen’s disease occurring over the right thumb, in a middle aged woman, who is a beedi maker, is being presented.
