Eyelid Mass as Initial Presentation of Breast Cancer: A Case Report

Purpose: We report a case in which eyelid mass was the initial presentation of breast cancer. The diagnosis of breast cancer was made after lid biopsy. Case summary: A 41-year-old female patient presented with a painful mass on the left lower lid after 1 month. There was a pinkish mass in the lateral portion of the tarsal conjunctiva, and computed tomography revealed a mass with an irregular margin on the lower lid connected to the left lacrimal gland. Biopsy was performed at the tarsal conjunctiva of the left eye, and histopathologic examination was suggestive of malignant epithelial cell neoplasm, especially metastatic carcinoma in the breast. The patient was diagnosed as having invasive ductal cancer, for which she is currently receiving chemotherapy. Conclusions: Metastases to the eyelid are very rare, accounting for less than 1% of all malignant eyelid lesions. We report a patient who presented with an eyelid mass as the initial presentation of breast cancer, which was diagnosed with metastatic breast cancer. J Korean Ophthalmol Soc 2017;58(5):591-594
