Familial paraganglioma (PGL) is a dominantly inherited disorder characterized by development of PGLs in the head and neck region. Germline mutations in genes coding for succinate dehydrogenase (SDH) subunits D, B, and C (SDHD, SDHB, SDHC) are found in almost all familial PGL patients. A 19-year-old female presented with pulsatile tinnitus and a reddish pulsating mass in the external auditory canal, and her mother complained of similar symptoms. Paraganglioma was found in both patients and was surgically removed. We report a case of germline SDHB mutation. This mutation was a deletion of thymine at nucleotide position 757 in exon 7 of the SDHB gene (c.757delT).
