Orbital Metastasis as Primary Presentation of Misdiagnosed Breast Cancer: A Case Report

Abstract

We report the case of orbital metastasis from a hormone-positive infiltrating lobular carcinoma in a previously misdiagnosed metastatic breast cancer in a 61-year old woman presenting with ophthalmic symptoms (diplopia, bulb proptosis). She received external beam radiotherapy, particularly 3D conformal radiotherapy, chemotherapy and hormone therapy. The metastatic involvement of the orbit in malignant tumors is a rarely diagnosed condition. Breast cancer accounts for the majority of these cases. This article highlights the importance of evaluating the one such unique metastatic site (orbital metastasis) as the first indication of advanced malignancy and reinforces the importance of an early correct diagnosis.
