Embryonal rhabdomyosarcoma

Last revised by Joshua Yap on 21 Jul 2022

The embryonal subtype of rhabdomyosarcoma is the most common variety of rhabdomyosarcoma, accounting for 50-70% of cases 1,2. It is typically seen in children below the age of 15.

Pathology

Embryonal rhabdomyosarcomas are further divided into three subtypes 1:

Location

Typically these tumors arise in the head and neck and genitourinary tract

Radiographic features

The features are non-specific (see radiographic features in the parent article: rhabdomyosarcoma), although, in general, embryonal rhabdomyosarcomas tend to be more homogeneous. When located in the extremities, they may cause bowing of long bones in children 1.
