title: Axillary metastasis as the first manifestation of occult breast cancer in a man: a case report.
abstract: Breast cancer is extremely rare in men, accounting for less than 1% of all breast cancers. We describe a male patient with occult breast cancer that was confirmed immunohistochemically. To our best knowledge, this is the first case presenting axillary and supraclavicular metastases as the first manifestation of occult cancer of the male breast.
