Kidney Tumors New and Emerging Kidney Tumor Entities

This article provides an overview of several new and emerging renal entities. The sum-mary of their key features is shown in Table 1. The awareness of these renal neo-plasms is essential for practicing pathologists because the navigation through this evolving field is a challenging task, even in places with large volumes of renal tumors. Such cases can, however, be seen in practices of any scope, and their correct clas-sification requires diagnostic awareness among general pathologists, because they can be often diagnosed, or at least suspected, on morphology in combination with IHC. The recognition of such novel renal entities will guide both pathologists and cli-nicians in translating these developments into more accurate diagnosis and better pa-tient management.
