Definition/Description[edit | edit source]
Proliferative myositis (PM) is a benign tumor which grows in skeletal muscle[1]. It is often mistaken for sarcomas (especially rhabdomyosarcoma)[2]. While etiology is unknown, it may result from injury to the muscle, fascia, or vasculature (resulting in ischemia) of the associated area[3].
Prevalence[edit | edit source]
As of 2008, only about 100 published cases existed, 25% of which dealt with proliferative myositis of the head and neck musculature[1].
Characteristics/Clinical Presentation[edit | edit source]
Signs and symptoms of PM:[1][2][4]
- Rapidly enlarging, solid tumor within skeletal muscle
- Localized inflammation
- No lymph node enlargement
- No significant laboratory results
