Orbital metastasis as the first presentation of nonpalpable invasive lobular carcinoma of the breast.

摘要

Up to 30% of the orbital masses are metastatic. Breast carcinoma is the most common primary source of orbital metastases in 29-51 % of cases, followed by lung, prostate, and colon cancer. Overall, 25-45 % of patients present with orbital symptoms as the initial feature of their primary cancer. Autopsy reports reveal this form of metastasis in 10-30% of breast cancer patients. Infiltrative or inflammatory syndrome is the initial presentation in nearly 54% of patients, which can be misdiagnosed. as scleritis, myositis, enophthalmitis, or inflammatory pseudotumor.
