An unusual orbital metastasis of breast cancer.

In this paper we report the clinical case of a 84 year old female patient with a history of breast cancer diagnosed 14 years before, treated only with hormone therapy for 10 years and with subsequent follow-up oncology which always demonstrated negative results. 14 years after the first diagnosis, the patient presented with an increase in mass markers (CEA), and progressive symptoms of the right eye (diplopia). A CT scan and an MRI of the orbits confirmed the presence of an expansive neoplastic formation of the right orbit of 16 × 9 mm. The orbital metastases are rare locations of metastatic breast cancer which pose problems of differential diagnosis and require prompt and multimodal treatment (chemotherapy, hormone therapy, radiation therapy) aimed at improving the quality of life of the patient.
