Non-Rhabdomyosarcoma (Non-RMS)






Non-RMS generally present as an increasing, painless mass.

Rarely associated with any warmth, erythema (redness) or tenderness.

Common sites include:

  • Extremity
  • Trunk
    • Posterior thorax
    • Flank
    • Abdominal wall

It is possible for these tumors to arise intra-abdominally, but this is very rare in children.

Pain only occurs when there is invasion of adjacent neuro-vascular structures.

There is no evidence that trauma is a cause of non-RMS, though sometimes these tumors are only noticed after trauma.

The average time interval between the initial symptom and diagnosis is 2 months (interval longer in adolescents than very young children).
