GISTs may mostly represent sporadic cases, but they could also be part of familiar syndromes, such as the Carney triad, Carney--Stratakis syndrome, and neurofibromatosis type 1 (2).
On the other hand, the similarly named Carney triad is a nonhereditary allelic condition that typically occurs in young females and is characterized by gastric GIST, PGL, and pulmonary chondroma.
The literature search for leiomyoma and GIST revealed only one published case of a 22-year-old girl with Carney triad who presented with metachronous gastric GIST and oesophageal leiomyoma [12].
Stratakis compiles 11 articles on the genetics of endocrine tumors, from classic multiple neoplasia syndromes to various germline or somatic mutations in sporadic tumors: multiple endocrine neoplasia type 1, 2, and 4; von Hippel-Lindau disease; Carney complex; pheochromocytomas and paragangliomas; Carney triad; pituitary, thyroid, and parathyroid tumors; and endocrine tumors associated with neurofibromatosis type 1, Peutz-Jeghers syndrome, and other familial neoplasia syndromes.
Recently those GISTs associated with Carney Triad, Carney-Stratakis syndrome, along with young and pediatric GISTs have been documented to have a loss of succinate dehydrogenase subunit B (SDHB) expression, a mitochondrial protein [41-43].
