Dedifferentiated liposarcoma with low-grade osteosarcomatous differentiation is at higher risk of early local recurrence than DDLPS without osteogenic differentiation.
Gradual enlargement of calcified components in lipomatous masses may indicate the presence of dedifferentiated liposarcoma with low-grade osteosarcomatous differentiation, highlighting the importance of preoperative radiologic diagnosis.

Dedifferentiated liposarcoma (DDLPS) with low-grade osteosarcomatous differentiation is extremely rare. However, this subtype is considered at a higher risk of early local recurrence than DDLPS without osteogenic differentiation, underscoring the importance of preoperative radiologic diagnosis. Here, we report a case of DDLPS with low-grade osteosarcomatous differentiation in an 80-year-old male located on the left dorsal thigh, in which long-term imaging follow-up was conducted prior to treatment. Gradual enlargement of calcified components in lipomatous masses may indicate the presence of DDLPS with low-grade osteosarcomatous differentiation.
