Abstract

Sarcomas constitute approximately 1% of adult cancers and 8%–10% of paediatric cancers. Undifferentiated pleomorphic sarcoma (UPS) is a type of soft-tissue sarcoma (STS) characterised by dedifferentiated cancer cells. The most common sites of metastasis for UPS include the lungs, liver, bones and regional lymph nodes. Brain metastasis is rare, affecting only 1%–8% of STS patients. This report presents a unique case of a woman in her 80s with a TET2-mutant UPS metastatic to the lung and brain.
