- Abstract
Carney syndrome is an autosomal dominant complex involving endocrinopathy, mucocutaneous hyperpigmentation, and different tumors, including cardiac myxomas. We report on a single family with several members affected with Carney syndrome. Family and individual medical histories were investigated in several Canadian provinces. The histology slides were also reviewed. Four family members (two young women, both sisters, their mother, and maternal grandmother) were found to harbor Carney syndrome. Everyone was presented with multiple and recurrent atrial myxomas of the heart, requiring multiple open cardiac surgeries. Breast myxomas and cutaneous hyperpigmentation were also revealed in one of the sisters and their mother. Interestingly, genetic testing was positive for the female family members and negative for the father and brother. We cannot rule out that the brother may have had a new mutation or harboring a mosaic. The young woman's brother did not have cardiac myxoma but developed a unilateral Sertoli cell tumor of testis. Carney syndrome is a rare complex multisystemic genetic disorder, including multiple and recurrent cardiac myxomas. We strongly suggest that reporting familial Carney syndrome is still critical in the 21st century to augment the awareness of this situation among clinicians and pathologists., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.
