Bowen's disease on finger: A diagnostic and therapeutic challenge.

ABSTRACT

Bowen's disease commonly presents as a solitary asymptomatic plaque involving head and neck region or lower limbs. We present a case of a sixty seven-year-old man with an itchy, oozy, crusted solitary plaque on the right ring finger of eighteen months duration with histopathology consistent with Bowen's disease. The lesion was initially treated with topical 5% imiquimod but due to relapse and inadequate response to a second course, complete surgical excision followed by full thickness skin grafting was done. Recurrence after about 6 months in the form of a small papule adjacent to the initial site was also treated with excision. This report highlights the potential of Bowen's disease to mimic more common dermatoses and a high index of suspicion, supported by histopathology, is required to diagnose and treat it without delay, which in turn may require a multimodality approach. We also reviewed the current literature on the same.
