Embryonal rhabdomyosarcoma (ERMS) is a rare histological form of cancer of connective tissue wherein the mesenchymally-derived malignant cells resemble the primitive developing skeletal muscle of the embryo. It is the most common soft tissue sarcoma occurring in children.[1]


ERMS is the more common of two major subtypes of rhabdomyosarcoma, the other being alveolar rhabdomyosarcoma.

It has been informally classified as a "small round blue cell tumor"[1] because of the characteristic microscopic appearance of its cells after histological staining with hematoxylin and eosin.

Prognosis and survival

The prognosis for rhabdomyosarcoma has improved greatly in recent decades, with over 70% of patients surviving for five years after diagnosis.[2]
