Abstract

The objective of our study was to characterize patterns of calcifications in synovial sarcoma. The presence of fine, stippled calcifications in a soft-tissue mass should raise suspicion for synovial sarcoma. These calcifications can coalesce to a deposit that mimics hydroxyapatite deposition disease or soft-tissue osteosarcoma. Spicules of calcification were a less common finding in our series; the appearance of spicules in synovial sarcomas overlaps with that of other soft-tissue sarcomas such as soft-tissue osteosarcoma and liposarcoma.
