ABSTRACT
AIMS:
Pseudosarcomatous reactive myofibroblastic proliferations have been described following surgery or trauma at a variety of anatomical sites. These types of reactions have not been previously described at injection sites. Here we evaluated prevalence, morphologic patterns and clinical resolution of such lesions. METHODS ANDRESULTS:
We analyzed 266 surgical resection specimens obtained during the definitive treatment of piriformis syndrome. Three cases showed exuberant reactive fibroblastic/myofibroblastic intramuscular proliferations, mimicking a sarcoma. In all three cases the surgeries were found to be preceded by local injections of cortisone and bupivacaine. Clinical follow-up revealed no uncontrolled growth.CONCLUSIONS:
As the clinical history of injections is often not provided, it is important to be aware of this pitfall when reviewing skeletal muscle resections for entrapment syndromes.
