Herein, we report the findings in a Chinese male breast cancer patient who developed choroidal metastasis, and give opinions on systemic treatments. A 45-year-old Chinese male represented with difficulty breathing and visual impairment in the left eye 6 years after his breast cancer surgery and postoperative adjuvant treatment. PET/CT revealed multi-organs metastasis of the patient. The IHC indicated the lung lesion to be originated from the breast (ER+/PR+/HER2-). Eye examination provided evidence for breast cancer choroidal metastasis. Two cycles of TX (docetaxel + capecitabine) followed by two courses of GP (gemcitabine + cis-platinum) were applied as salvage chemotherapy. Metastases in his lung and bone remained stable. As for choroidal metastasis, a regimen of CDK4/6 inhibitor (Palbociclib) plus fulvestrant was recommended to the patient, which led to a good response. Notably, CDK4/6 inhibitor combined with endocrine therapy may be considered as an effective treatment for hormonal receptor-positive breast cancer patients with choroidal metastasis. We recommend that eye examination should not be neglected in breast cancer patients.Keywords: choroidal metastasis, male breast cancer, systemic therapy, CDK4/6 inhibitor, case report
