Succinate dehydrogenase deficient renal cell carcinoma: A case report

Abstract

Succinate dehydrogenase (SDH) deficient renal cell carcinoma (RCC) are uncommon renal tumors that typically present in relatively younger patients. SDH mutations are known to cause cancer, but often presents with hereditary paragangliomas, pheochromocytomas, and gastrointestinal stromal tumors. This report details a case of SDH deficient RCC in a patient with no know contributing family history. Patient presented with recurrent urinary tract infections and groin pain. Computerized tomography (CT) revealed a 4 cm mass in the right kidney. Partial nephrectomy was performed, and the patient had an uneventful recovery. Immunohistochemical staining revealed the tumor was SDH negative.
