Working Diagnosis:
Synovial Sarcoma
Treatment:
Patient initially underwent several rounds of neoadjuvant chemotherapy along with radiation therapy.
<br>Radical surgical resection in January with negative margins
<br>Followed by adjuvant chemotherapy
<br>
<br>Chemotherapy was complicated by neutropenia, nausea/vomiting, heart thrombus now on xarelto
Outcome:
Patient is still undergoing chemotherapy and on anticoagulation, and is not participating in sports at this time
<br>She is a senior in high school and is on track to graduate
<br>Plans to attend college, not planning on playing collegiate sports
Author's Comments:
Rare cancer found in children, adolescents, and young adults with a mean age of 35
<br>6-8% of soft tissue sarcomas, and is found in limbs about 66% of the time, but can be found anywhere in the body
<br>Poor prognostic predictors include:
<br>size >5 cm
<br>deep seated
<br>mitotic activity of >10 cells per high power field
<br>inadequate surgical resection/local recurrence
<br>patient age >20 years
<br>
<br>The main teaching point of this case is not to miss this diagnosis. When you are concerned for a mass and you are unsure exactly what it is, you are never wrong to order imaging.
Editor's Comments:
Careful physical exam is another teaching point in this case. Physical exam is used to narrow the differential diagnosis you made during history.

<br>As her sports medicine physician, we can work in conjuction with her oncologist and cardiologist for an exercise prescription appropriate for an anticoagulated teen receiving chemotherapy.
