Background: choroidal melanoma is considered the most common malignant tumor in adults. It usually appears between the sixth and seventh decade of life and it is diagnosed by ophthalmoscopy, biomiscroscopy, ultrasound and fluorescein angiography. Choroidal melanoma presentation may be in its nodular or diffuse variant; malignancy depends on the size of tumor, location, extrascleral extension, histological type, among other factors. The cause of death from this disease usually occurs by hepatic metastases. Objective: to avoid late diagnosis of ocular melanoma. Case presentation: a 50-year-old-female patient presented with slow decrease of visual acuity in the right eye. The eye test detected the presence of a brown tumor mass occupying the upper hemiretina, which was corroborated with the observation of ocular ultrasound. It was decided to enucleate the eyeball due to its characteristics. Histopathological examination confirmed the presence of a choroidal melanoma of mixed cell type with ciliary body infiltration. Results of physical, hematological and imaging examination were negative, ruling out the presence of metastasis.
