An early orbital metastasis from breast cancer: A case report.

INTRODUCTION

Orbital metastases from solid cancers are infrequent or underestimated, since they represent only 1-13% of tumors of the orbit. They are even less frequent in breast cancer and are rarely diagnosed. We report a case of an early diagnosed orbital metastasis from breast cancer to an extra ocular muscle.

CASE REPORT: We report the case of a 33-year-old female patient who presented, following the diagnosis of her breast cancer, headache, a progressive decrease in visual acuity of the right eye and diplopia. Brain imaging revealed a tissue process at the expense of the internal rectus muscle, which biopsy pointed to a secondary lesion of breast cancer.

DISCUSSION: Extraocular muscles are rarely infiltrated by metastasis from distant sites. They are mostly asymptomatic and suggest a systematic spread of the disease. The treatment is generally palliative and the prognosis is generally poor.

CONCLUSION

Orbital metastases from breast cancer are certainly rare but are associated with significant morbidity. In order to make a precise diagnosis and offer an appropriate treatment, healthcare professionals must remain vigilant in the face of any ophthalmological symptoms.
