Recurrent extramammary Paget’s disease successfully treated with peripheric Mohs micrographic surgery associated with rapid immunohistochemistry

Extramammary Paget's disease is a slow-progressing, cutaneous adenocarcinoma of the apocrine glands with an uncertain etiology. The standard treatment is surgical removal of the tumor. However, the usual surgical methods - wide local excision and Mohs micrographic surgery - pose challenges and high recurrence rates. Often, these are extensive lesions with poorly defined boundaries located in critical anatomical regions. Additionally, they exhibit unpredictable subclinical intraepithelial spread. We present a case of a recurrent extramammary Paget's disease successfully treated with peripheric Mohs micrographic surgery associated with rapid immunohistochemistry for CK8/18.
