Undifferentiated pleomorphic sarcoma (UPS) is a rare tumor of mesenchymal origin affecting the hand in less than 3% of cases. A 92-year-old male reported an enlarging, painless mass on his left hand of three months duration. Examination of the hand revealed a soft, non-tender, immobile mass over the wrist joint, just proximal to his thumb. Immunohistochemistry findings on ultrasound-guided biopsy were consistent with UPS. Further intractable pain, ulceration, and bleeding necessitated urgent radiotherapy, which provided no relief. This was followed by amputation above the elbow. Seven months later, the patient presented with confusion. A chest X-ray revealed extensive bilateral pulmonary metastases. In light of this result, the patient was referred to the palliative care team. UPS carries a poor prognosis, with a high risk of metastases. Early diagnosis and treatment is required for optimal clinical outcomes. Through this case, we highlight the need for a more effective treatment strategy to improve clinical outcomes.
