Recurrent apocrine carcinoma of the scrotum: A case report

Apocrine carcinoma is a rare tumor of the skin that typically arises in areas rich in apocrine glands, such as axilla and perineum.The main differential diagnosis is a metastasis from a primary apocrine carcinoma of the breast.Several authors have attempted to define morphological and immunohistochemical parameters to differentiate metastasis from primary apocrine carcinoma of the skin, but none of these had been demonstrated to be reliable markers.Here, we report a case of primary apocrine carcinoma of the scrotum that relapsed three times within a few years, without any clinical or radiological evidence of any other tumor of breast or other sites.
