Rare concurrent liposarcoma and Ewing's sarcoma suggests increased second malignancy risk in sarcoma patients.
Case Report (n=1)
Sarcoma patients may be at increased risk of a second malignancy, implying a need to search for occult tumors during follow-up.

May warrant vigilance for second primaries in sarcoma follow-up; hypothesis-generating from Level 5 evidence.
The development of different entities of soft tissue sarcoma in one patient is rare. It usually affects head and neck or abdominal region, whereas those affecting the extremities are much rarer. We describe a patient with double primary presentation of liposarcoma and Ewing's sarcoma in extremity. This case implies that sarcoma patients are at increased risk of a second malignancy, and this implies a need to search for occult tumors during follow up.

Park et al. (2011) conducted a case report in Double primary presentation of liposarcoma and Ewing's sarcoma (n=1). A patient presented with a rare double primary presentation of liposarcoma and Ewing's sarcoma in an extremity, suggesting an increased risk of a second malignancy in sarcoma patients.
