- most common malignant neoplasm affecting infants less than 1 year of age
- arises from the neural crest (MCQ)
- most commonly found in the adrenal medulla (MCQ)
- it may arise anywhere along the sympathetic chain, including the neck.
- Abdominal mass and fever are presenting signs.
- Some are incidentally found by prenatal ultrasound.
- Diffusely metastatic tumors to liver, bone marrow, and skin produce the
- so-called ‘blueberry muffin’ clinical appearance. (MCQ)
- Neuroblastomas secrete catecholamines
- vanillylmandelic acid [VMA]
- homovanillic acid [HVA])
- urine testing for these compounds can confirm the diagnosis and monitor for recurrence.
- Microscopically, these tumors are arranged in sheets and pseudorosettes of
- small round blue cells. (MCQ)
- Tumor cells immunostain for neuroendocrine markers, such as chromo-
- granin. (MCQ)
- In time, or after treatment, these tumors may mature revealing ganglion cells and mature neural tissue.
- Genetic aberrations include
- deletion of 1p(MCQ)
- N-myc gene amplification
- N-myc amplification is associated with aggressive behavior(MCQ)
- Hyperdiploidy is associated with a better prognosis. (MCQ)
