Extramammary Paget's disease in 1893, Darier and Coulillaud described the perianal location of EMPD. Extramammary Paget's disease Extramammary Paget’s Disease (EMPD), is a rare and slow-growing malignancy which occurs within the epithelium and accounts for 6.5% of all Paget’s disease. The clinical presentation of this disease is similar to the characteristics of Mammary Paget’s disease (MPD). However, unlike MPD, which occurs in large lactiferous ducts and then extends into the epidermis, EMPD originates in glandular regions rich in apocrine secretions outside the mammary glands.
