Question 12 - Single Best Answer
The most common type of childhood soft tissue sarcoma (cancer or malignant tumor) is rhabdomyosarcoma. Here is a photo. Notice the heterogeneity in cytoplasmic and nuclear size as well as the abnormal nuclear contents. This tumor is most commonly found in the head and neck region. In a well-differented tumor (a tumor that looks like an overgrowth of otherwise normal tissue), what type of muscle fiber would you expect to see?
smooth muscle skeletal muscle cardiac muscle
