PURPOSE: To report a case of a patient with lung carcinoma in which the first detected metastasis was to the choroid, how it was diagnosed and confirmed. METHODS: A 35 year-old white male, while being treated for a solitary pulmonary condensation, reported sudden loss of vision, pain, discharge and red eye (right eye) for 10 days. During the ophthalmic examination a nonregmatogenous retinal detachment as well as multiple choroidal tumors were confirmed by diagnostic ocular ultrasound. Fine-needle aspiration biopsy (FNAB) was suggested to diagnose a possible metastatic disease. Fine-needle aspiration biopsy was performed under peribulbar anesthesia with sedation. A transvitreous route was chosen through a sclerotomy 4 mm from the limbus. The procedure was monitored via binocular indirect ophthalmoscopy. Two sample aspirates were obtained from different tumour foci. After fine-needle aspiration biopsy, the aspirates were sent for processing, fixation and stained with Papanicolaou and HE. RESULTS: Cytology confirmed the diagnosis of multiple metastatic tumors. Immunocytochemistry of ocular and lung aspirates revealed a common cell origin by a pankeratin (AE1/AE3) positive test. Regardless of systemic treatment with chemotherapy and improvement of the ocular status, the patient died 4 months after cytological diagnosis of metastatic carcinoma of the choroid. CONCLUSIONS: Fine-needle aspiration biopsy was efficient to diagnose and correlate ocular cytology with the primary tumor by imunohistochemical methods in this case. Fine-needle aspiration biopsy should still be used only in selected cases and further research will be necessary for it to become a standard diagnostic procedure in ophthalmology.
