[Clinicopathological characteristics of fumarate hydratase-deficient renal cell carcinoma].
Objective: To investigate the clinicopathologic characteristics, molecular and genetic features, differential diagnoses and prognosis of fumarate hydratase-deficient renal cell carcinoma (FH-RCC). Methods: The immunohistochemical (IHC) expression of FH in 391 renal neoplasms in tissue chips collected from the Affiliated Hospital of Qingdao University and 971 Hospital of PLA Navy from January 2011 to December 2017 was evaluated. The clinicopathologic data of eight FH negative cases were collected. ⋯ The negative expression of FH and the detection of FH gene mutation could facilitate the diagnosis of the tumor. FH-RCC is a high aggressive tumor, prone to metastasize, and is associated with poor prognosis. The timely diagnosis of FH-RCC could benefit the patients and their relatives as well.
