This case describes new onset mammary Paget disease arising in the background of Darier disease. Clinically and histologically, lesions of Darier disease can mask the lesions of mammary Paget disease. A high index of suspicion is necessary to diagnose Paget disease in a patient with Darier disease, for a potentially fatal disease could easily be missed.
