๐ŸŽ—๏ธ Chapter 590 ยท Gynecologic Neoplasms & HPV Prevention

Nelson Textbook of Pediatrics 22nd Edition โ€” Gynecologic malignancies account for 1.3% of childhood cancers. Ovarian germ cell tumors (dysgerminoma, yolk sac, immature teratoma) are most common. Sarcoma botryoides (embryonal rhabdomyosarcoma) presents as grapelike mass in vagina <3 years. HPV vaccine (9-valent) recommended at ages 11-12. Cervical cancer screening begins at age 21 (immunocompetent). Fertility preservation is key: unilateral oophorectomy + ovarian tissue cryopreservation for prepubertal patients.

๐Ÿ”‘ Key Principles (Nelson Ch.590)
โ€ข Ovarian germ cell tumors: Most common gynecologic malignancy in adolescents. Dysgerminoma (best prognosis), yolk sac (AFP elevated), immature teratoma.
โ€ข Sarcoma botryoides: Embryonal rhabdomyosarcoma, grapelike mass in vagina, age <3 years. Treatment: VAC chemotherapy.
โ€ข Fertility preservation: Unilateral salpingo-oophorectomy (fertility-sparing) for early-stage malignant germ cell tumors. Ovarian tissue cryopreservation for prepubertal patients.
โ€ข HPV vaccine (9-valent): Ages 9-26. Two doses if started <15 years (0, 6-12 months). Three doses if โ‰ฅ15 years or immunocompromised.
โ€ข Cervical cancer screening: Start at age 21 (Pap alone). HPV testing not recommended <25.
