AN 11-YEAR-OLD African American boy presented to his local physician with a complaint of painless swelling in the right calf. The lesion subsequently increased in size, and 2 months later he was limping and complaining of pain in the leg. Magnetic resonance imaging of the knee revealed a lobulated heterogeneous soft tissue mass in the lateral head of the gastrocnemius muscle with associated edema in the surrounding musculature (Figure 1). A deep-seated, tennis ball–sized mass was subsequently resected 2 weeks later. The resection included the lateral head of the gastrocnemius muscle, underlying soleus muscle, and surrounding soft tissues. The closest margin was along the neurovascular bundle in the popliteal space. There was no attachment of tumor to the periosteum or synovium.
