| *The most popular theory is that Extramammary Paget's disease (EMPD) may arise either as a primary intraepidermal neoplasm of the epidermis (i.e, primary EMPD) or less commonly as a result of spread from an underlying internal malignancy (i.e, secondary EMPD).
| |
| *In primary EMPD, Paget's cells probably originate from primitive basal cells within the [[epidermis]] or from intraepidermal portions of [[apocrine glands]]. Primary Paget's disease may progress from in situ intraepidermal neoplasia to dermally invasive [[adenocarcinoma]], which may in turn metastasise to distant sites and local [[lymph nodes]].
| |
| *In secondary EMPD, Paget's disease arise following epidermotropic spread of malignant cells from an underlying neoplasm in a dermal adnexal gland or a local internal organ with contiguous epithelium.
| |
| *Some investigators believe that EMPD may be associated with a generalised tendency to neoplasia, especially [[adenocarcinoma]], as there is a high rate of metasynchronous and synchronous cancers in these patients. An association of EMPD of the vulva and high grade vulval intraepithelial neoplasia (VIN) has been reported by some authors.<ref>Lever, Walter F., and David E. Elder.
