Carney and Stratakis reported familial clustering of paraganglioma and gastric stromal sarcoma distinct from sporadic cases with Carney triad. Subsequently, germline mutations in the genes associated with familial paraganglioma were detected in this type of families.[2,3]. Negative immunohistochemistry for SDHB is a feature of the gastric stromal tumors in Carney-Stratakis syndrome as well as in the sporadic Carney Triad[4].
