Lymphoproliferative disease of the orbit.

Lymphoproliferative disease of the orbit represents a diverse group of lesions affecting various soft tissue structures within the orbital cavity. They are one of the most common disease entities encountered in orbital pathology and frequently present with proptosis or anterior tumefactive swelling in the lids, conjunctiva, and lacrimal glands. For elucidation of the underlying cause, computed tomography and magnetic resonance imaging are the optimal imaging modalities.
