The Genitourinary Pathology Society (GUPS) have also proposed updated classifications to renal neoplasia by introducing three categories—novel entity (validated by multiple studies), emerging entity (good data from some studies, but requires more validation), and emerging entity (limited data available)—with the aim of reducing the category of “unclassifiable renal carcinomas/tumours.” Novel entities include eosinophilic solid and cystic RCC, RCC with fibromyomatous stroma (previously RCC with leiomyomatous or smooth muscle stroma), and anaplastic lymphoma kinase rearrangement-associated RCC. Here, ALK is linked to renal cell carcinoma.
