The mass had been increasing in size for the past six months, affected by local and systemic infection. While it was initially painless, the patient started feeling discomfort during sitting and physical activities a few weeks, but later the complication of tumor became more aggressive.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>UPS can arise in various anatomical sites, including the extremities, trunk, retroperitoneum, and head and neck region. Clinically, UPS may present as a rapidly growing mass, often with pain and limited range of motion. However, the presentation may vary depending on the site of origin. Treatment for UPS typically involves surgical resection, aiming to remove the tumor completely. Depending on the size, location, and aggressiveness of the tumor, additional treatments such as radiation therapy or chemotherapy may be recommended.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Undifferentiated pleomorphic sarcoma (UPS) represents a rare and aggressive soft tissue sarcoma requiring prompt and accurate diagnosis for appropriate management.
