Teratoma: Teratoma - epidemiology
(The 5-Minute Pediatric Consult)

  • Gonadal and extragonadal germ cell tumors account for ~3% of childhood malignancies (<15 years) and 15% of malignancies of ages 15–19 years.
  • Incidence of germ cell tumors as a whole is ~2.5 cases per million in white children and 3 cases per million in black children <15 years of age.
  • Boys and girls are equally affected.
  • One suggestive epidemiologic association is with high maternal hormone levels during pregnancy.
  • More controversial associations include younger gestational age; viral infections including herpes simplex virus, varicella-zoster virus, cytomegalovirus, mumps; other congenital anomalies; maternal urinary tract infection or tuberculosis; and paternal occupation in chemical industries.
  • Sacrococcygeal teratoma: Accounts for 40% of all childhood germ cell tumors and up to 78% of extragonadal germ cell tumors. Most prevalent in infants; girls more frequently affected
  • Testicular and ovarian tumors: Most prevalent in infants and adolescents
  • Vaginal tumors: Most prevalent in girls <3 years old
  • Mediastinal tumors: Average age of the pediatric patient is 3 years, but also found in adolescents; most common extragonadal germ cell tumor in adults

About prevalence and incidence statistics:

The term 'prevalence' of Dermoid cyst usually refers to the estimated population of people who are managing Dermoid cyst at any given time. The term 'incidence' of Dermoid cyst refers to the annual diagnosis rate, or the number of new cases of Dermoid cyst diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
