Abstract
Fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) is a rare aggressive type of renal cell carcinoma. The significant morphologic overlap with other types of renal neoplasia and the limited availability of FH and 2-succinylcholine immunostains for diagnostic use outside large referral centers have created numerous diagnostic pitfalls. As FH-deficient RCC can be associated with hereditary leiomyomatosis and renal cell cancer syndrome, the importance of an accurate diagnosis goes beyond the prognosis and treatment of an individual patient. We present 2 patients with FH-deficient RCC showing a peculiar pattern of GATA3 immunoexpression restricted to tumor nucleoli. If confirmed in further larger studies, this could provide an additional diagnostic clue for considering the FH-deficient RCC diagnosis, and given the frequent papillary morphology and possible hilar location can lead to the misdiagnosis as high-grade urothelial carcinoma, and is an important diagnostic pitfall to be aware of.
