Classification of Retinal and Retinal Pigment Epithelium Tumors

Abstract

Tumor classification is important as it creates a common terminology that allows clinicians and researchers to accurately communicate, thus facilitating diagnosis by helping the clinician to include all conditions that are relevant in a differential diagnosis. Classification allows us to draw historical, international, or multicenter clinical and biological comparisons, thus improving our ability to understand the natural course of tumors and facilitate research into new treatments. In this chapter, the term “tumor” is used in its broadest sense as a mass without implication to its pathogenesis or its neoplastic or malignant properties.
