  23 August

  Fumarate Hydratase–deficient Pheochromocytoma and Paraganglioma
  Definition : Up to 40% of pheochromocytomas (PCCs) and paragangliomas (PGLs) are hereditary. Germline mutations/deletions in fumarate hydratase (FH) cause hereditary leiomyomatosis and renal cell carcinoma syndrome which manifests predominantly with FH-deficient uterine/cutaneous leiomyomas and renal cell carcinomas (RCCs)—tumors characterized by loss of immunohistochemical (IHC) expression of FH and/or positive staining for (...)
