Abstract: Undifferentiated pleomorphic sarcoma (UPS) is commonly found in deep soft tissues, but cutaneous and subcutaneous lesions are relatively rare. The lack of specific symptoms and characteristic manifestations under the microscope makes the diagnosis and treatment of UPS difficult. In April 2022, a patient who was initially diagnosed with cyst infection of the scalp through superficial ultrasound and symptoms was admitted to the Medical Cosmetic Center of the First Affiliated Hospital of Zhengzhou University. After the lesion was resected through surgery, the pathological result showed that the lesion combined UPS. Subsequently, the patient underwent a tumor extended resection, followed by chemotherapy. After 8 months of follow-up, the patient’s prognosis was favorable. This case report aims to provide a reference for the diagnosis and treatment of cutaneous UPS by thoroughly reviewing the diagnostic and therapeutic process of this patient and systematically reviewing related literature.
