Cardiac paraganglioma with a novel germline mutation of succinate dehydrogenase gene D

Abstract

A 58-year-old woman with a past medical history of a carotid body tumor, resected 4 months prior to presentation, was admitted to our hospital for treatment of a cardiac tumor that was identified on post-operative echocardiography and chest computed tomography. The cardiac tumor was surgically removed and identified pathologically as a paraganglioma, similarly to the carotid body tumor. Genetic analysis of both tumors identified a non-synonymous mutation in the succinate dehydrogenase (SDH) gene D, Exon4, c.320T>C, p.Leu107Pro showing co-segregation with paternal transmission and maternal imprinting among family members. This novel mutation appears to be the cause of familial paraganglioma in this patient.
