To report the case of a patient who presented with a solid anterior segment intraocular mass in his right eye, and the diagnostic investigation chosen by the authors. Diagnostic uncertainty and patient's refusal to agree with the treatment caused the authors to perform a fine needle aspiration biopsy of the lesion. Biopsy was performed by corneal puncture, through the aqueous and the tumor. Cytology of the specimen obtained by the biopsy determined the therapeutic strategy for this case. Cytology diagnosis was consistent with primary malignant melanoma of the choroid of mixed cell type. Enucleation of the eye was suggested due to the position of the tumor and its potential to spread distant metastases. After enucleation, anatomopathological examination of the eye presented a similar result to cytology. The patient is currently been followed, with no signs of metastasis 2 years after enucleation.
