dear Editor,Extramammary Paget disease(EmPD)is a rare adenocarcinoma that originates in the apocrine gland-rich skin and usually affects the perineal skin(primary EmPD)or represents the intraepithelial spread of an underlying visceral carcinoma(secondary EmPD).Approximately half of EmPD cases are confined to the epidermis,which was defined as intraepithelial EmPD.
