How do disease presentation and treatment in extramammary Paget disease (EMPD) differ by anatomic subtype? This meta-analysis of 135 studies found that, despite typically being intraepidermal, vulvar disease was more likely treated with radical surgery. Nearly one-third of vulvar cases recurred, predominantly locally in the skin and mucosa and one-third of perianal EMPD cases recurred; however, one-third of those recurrences presented as regional or distant metastasis and penoscrotal EMPD was least likely to recur.
