Study Notes
Germ Cell Tumors (GCTs)
- A more toxic regimen is reserved for recurrence.
- Radiotherapy is the mainstay for intracranial GCTs.
Sacrococygeal Teratomas (SCT)
- A congenital tumor containing derivatives of the three embryonic germ layers.
- Arises at the tip of the coccyx.
- The most common solid tumor in the neonate.
Hepatoblastoma
- Unresectable primary, multifocal tumors may be treated with:
- Liver resection.
- Liver transplantation.
Neuroblastoma
- An enigmatic embryonal tumor arising from neuroblasts with somewhat unpredictable behavior.
Neuroblastoma Treatment
- Biopsy methods:
- Laparotomy or thoracotomy with classical open biopsy.
- Laparoscopy or thoracoscopy with biopsy.
- CT/USG-guided true-cut biopsy.
- Fine needle aspiration.
- Surgery may be performed.
Neuroblastoma Complications
- Hemorrhage.
- Renal ischemia.
- Intestinal ischemia.
- Prolonged ileus, bowel obstruction, intussusception.
- Chylous ascites.
- Vascular injuries with consequent morbidity.
Teratomas
- Derived from the Greek words "teratos" meaning monster and "onkoma" meaning swelling.
This quiz covers the diagnosis and treatment of germ cell tumors in pediatrics, including sacrococygeal teratomas and intracranial GCTs.
