A case of prolonged disease-free survival in a patient with choroidal metastasis from breast cancer.

BACKGROUND: A 57-year-old woman presented with distorted vision and decreased visual acuity (finger count only) in her left eye, 6 years after she had undergone a lumpectomy, lymph-node dissection, and radiation therapy for a 1.1 cm infiltrating ductal carcinoma of her right breast. A year before this presentation, she had completed 5 years of adjuvant tamoxifen therapy. INVESTIGATIONS: Physical examination, including a thorough ophthalmologic evaluation; laboratory investigations, ocular fluorescein angiography, ocular ultrasonography, head CT, chest X-ray, abdominal ultrasonography, bone scan, and bilateral mammography. DIAGNOSIS: Choroidal metastasis from breast carcinoma, with no other evidence of disease recurrence. MANAGEMENT: Radiation therapy to the left eye followed by ongoing hormonal therapy with oral letrozole 2.5 mg daily for the past 9.5 years.
