Mammary Paget's disease. I wanted to point out that there are 2 views, one of a crusted area and one where there isn't as much crust. I was stuck by the fact that the crusted piece was sparse on atypical cells (Figures 2 and 4). A reminder to carefully examine all pieces and correlate with the clinical photo if possible. The clinical suspicion for mammary Paget"s disease was high; the patient had no known prior history of breast CA.
