The differential diagnosis is important for tumors that share histological features with SCL, such as the well-differentiated sclerosing liposarcoma.[6] Immunohistochemistry had revealed spindle cell positivity for CD34, which has been used as a diagnostic marker for SCL.[7] In the present case, the tumor cells did indeed exhibit immunoreactivity for CD34. The gene discussed is CD34; the disease is liposarcoma.
