Unilateral acquired blepharoptosis due to orbital metastatic disease as an initial presentation of an overlooked breast carcinoma - A case report.

introduction and importanceOrbital metastasis from breast cancer may be infrequently noted after the management of the primary lesion. It is rare in such cases to present with unilateral mechanical blepharoptosis without ophthalmoplegia. CASE PRESENTATION: We present a case of unilateral acquired blepharoptosis of the left upper eyelid without ophthalmoplegia or exophthalmos three years after the onset of a suspicious breast mass. The patient did not disclose a history of breast cancer nor any positive family history to the ophthalmologist and anesthesiologist. The radiology images revealed an ill-defined enhanced lesion at the superior medial aspect of the left orbit. The orbital biopsy of the lesion showed poorly differentiated carcinoma as per the initial histopathology report. Vigilant history-taking enabled us to get information about a previous breast lesion and to correlate this with specific histopathological findings. DISCUSSION: Management of orbital lesions might be challenging, and the approach should include detailed history and assessment. Biopsy and radio imaging are further needed to aid in providing the proper diagnosis. The clinicopathological correlation in our case has led to the final diagnosis of orbital metastatic breast cancer.

conclusionOphthalmologists should be aware of variable ocular presentations of malignancy and adopt a team approach to obtain a carefully detailed history from patients presenting with orbital diseases and communicate adequately with the ocular pathologists who are handling the biopsy. Long-term follow-up and enhancement of patients' awareness of possible late orbital metastasis are recommended in all patients with breast masses.
