This week's artwork was donated by Gavin, a pediatric cancer patient who received treatment at The Children's Hospital of Philadelphia . Local invasiveness characterizes this low grade tumor. They arise in skeletal muscles or their fascia. They are of connective tissue origin. Growth is relatively slow compared with most tumors, but aggressive accelerated growth is also seen, as this is a heterogeneous group.
Desmoid tumors are almost always non-metastatic.
Deeply infiltrating lesions can invade into surrounding muscle. The mainstay of treatment has always been surgery. Treatment aims to have a curative effect with a good functional and cosmetic outcome. These patients were treated from 1965 to 1994. Median follow-up was 7.5 months.
