Primary cutaneous apocrine adenocarcinoma (PCAC) is an extremely rare neoplasm involving the sweat glands. Due to a lack of cases, there is no consensus for the systemic treatment of locally advanced or metastatic PCAC. Anti-androgen therapy may have activity in inoperable or metastatic PCAC with high androgen receptor (AR) expression.
Keywords: Primary cutaneous apocrine adenocarcinoma; androgen receptor; anti‐androgen therapy; metastatic cancer; sweat glands.
