Uveal tract lymphoma most frequently occurs as a secondary location of systemic disease. The presence of a tumor in the choroid and ciliary body with an extensive orbital component may indicate a primary lymphoma or metastatic disease. In the image, the gross examination of a specimen shows a whitish, solid, and homogeneous tumor located at the posterior pole of the choroid and at the entire posterior orbit. Note that the tumor is also present in the ciliary body. In the second image, the tumor surrounds the optic nerve, mimicking a meningioma. In this patient, histopathological examination with immunohistochemistry confirmed the diagnosis of large B-cell lymphoma.
