Extramammary Paget's disease: presenting in an unusual site

Extramammary Paget's disease [EMPD] is a rare neoplasm with only a limited number of reported cases in literature. It is mainly composed of intraepidermal Paget cells and possesses variable clinical behaviour and histological appearance leading to difficulty in diagnosis.
