Neuroblastoma mnemonic

Hello!

The term neuroblastoma is commonly used to refer to a spectrum of neuroblastic tumors (including neuroblastomas, ganglioneuroblastomas, and ganglioneuromas) that arise from primitive sympathetic ganglion cells and, like paragangliomas and pheochromocytomas, have the capacity to synthesize and secrete catecholamines.

Remember the N myc mnemonic for neuroblastoma :

N - Neuroblastoma, N myc gene
M - Crosses midline (differentiates from Wilms)
MY - MYoclonus (Opoclonus myoclonus)
C - Calcifications in tumor present
C - Catecholamine secretion

You can also remember "High BP" for additional findings seen in neuroblastoma:

Horner syndrome
Heterochromia iridis (different colors of the iris or portions of the iris)
Hypertension
Homovanillic acid and vanillylmandelic acid elevated in urine
Bombesin positive
Back pain
Bone pain
Beckwith-wiedemann syndrome association
Posterior mediastinum or retroPeritoneal mass
Pseudorosette
Purple skin lesions
Proptosis
Periorbital ecchymoses

That's all!
