ENDOGENOUS NOCARDIA ENDOPHTHALMITIS PRESENTING AS A MASS LESION IN A PATIENT WITH METATSTATIC NONSMALL CELL CARCINOMA OF THE LUNG

摘要

Purpose: To report a case of Nocardia cyriacigeorgica endophthalmitis.Methods: Case report.Results: A 71 -year-old man on long-term steroid therapy for poor respiratory function from lung carcinoma and presumed recent liver metastases presented with a four week history of blurry vision in the left eye. Ophthalmic examination revealed a white elevated mass in the macula with hemorrhage, concerning for metastasis. The patient was treated for presumed ocular metastases but had poor response to radiotherapy and was diagnosed four weeks later with N. cyriacigeorgica by retinal biopsy. Despite intravitreal and systemic antibiotics, the patient had progression of disease and died of respiratory involvement.Conclusion: Nocardia endogenous endophthalmitis can present as a mass retinal lesion in immunosuppressed patients with metastatic disease. Early vitreous and retinal biopsy may be required for definitive diagnosis and treatment. A pulmonary source of infection should be suspected and monitored closely.
