Characteristics and karyotype analysis of a patient with turner syndrome complicated with multiple-site tumors: A case report.

Turner syndrome (TS) is a congenital chromosomal abnormality that affects approximately 1 in 2,500 people. Both in China and abroad, few studies exist on the incidence of tumors in patients with TS. Most reported cases are complicated with gonadal germ cell tumors, and extragonadal tumors are rare, with the latter not yet being reported in China. Through chromosome karyotype analysis and surgical exploration, a pediatric patent was diagnosed with TS complicated with gonadoblastoma and adrenal neuroblastoma. The patient was short in stature and had a facial deformity. After admission, adrenal computed tomography was conducted, and a right adrenal mass was identified as a neurogenic tumor. After surgical resection and gonadal exploration, the pathological results revealed left gonadoblastoma, right gonadal stromal cell hyperplasia, and ganglion neuroblastoma (mixed type) in the right adrenal gland. Pediatric patients with TS have an increased likelihood of developing neuroblastoma and adrenal-related tumors, and changes in adrenal hormone levels and clinical manifestations are often not obvious when combined with adrenal-related tumors. To avoid missed diagnosis and delayed treatment, screening for adrenal tumors is therefore recommended for patients with TS before the initiation of growth hormone treatment.
