There is a paucity in guidelines for the management of extramammary Paget's disease (EMPD), a rare intraepithelial adenocarcinoma commonly involving the anogenital regions. 1 Wide surgical resection is the mainstay therapy but causes significant morbidity. 1 High-dose-rate brachytherapy (HDR-BT), a form of radiotherapy, delivers a high, conformal radiation dose to the target tissue through flexible catheters secured within customized surface molds. 2 We report three patients successfully treated with HDR-BT for their biopsy-confirmed and skin-limited EMPD and review cases treated with this method in the literature (Table 1).
