Comment

This familial disorder is characterized by the association of sacrococcygeal bony defects, (anterior) meningoceles (50%) and a presacral masses (42% mainly teratomas, lipomas and cysts) [1-6,10]. Prolonged constipation may be the only presentation in this syndrome. Associated findings include anorectal stenosis, occasionally Hirschsprung's disease[8] and vesicoureteral reflux. The risk of malignant transformation of the presacral teratomas appears to be lower than the 1% risk of malignant change in sacrococcygeal teratomas. In rare cases a neuroendocrine carcinoma arises in the teratoma of Currarino syndrome patients[11]. Malignant transformation has been diagnosed in children as well as in adults with the syndrome[12]. Leiomyomatosis peritonealis disseminata was reported in a patient with Currarino syndrome[9]. In general, a high frequency of children with sacrococcygeal teratomas have congenital anomalies of the lower vertebrae, genitourinary system and anorectum[7].
Germline mutations in the HLXB9 gene have been detected in almost 50% of patients with Currarino syndrome, 90% in familial cases[6,13].
