Abstract

High-grade oncocytic tumor (HOT) was recently proposed as a novel renal entity that is currently not included in the WHO classification. The first published series by He et al included 14 tumors, collected from multiple institutional files. Recently, Chen et al reported another series of 7 morphologically very similar tumors that they designated "sporadic renal cell carcinomas with eosinophilic and vacuolated cytoplasm". Using Next-generation sequencing they identified somatic inactivating mutations of TSC2 in 3 of 5 tumors tested or activating mutations of MTOR (in 2 of 5 tumors tested).
