头皮未分化多形性肉瘤伴囊肿感染1例

Undifferentiated pleomorphic sarcoma of the scalp combined with cyst infection: a case report

未分化多形性肉瘤常发生于深层软组织, 皮肤及皮下较少见。该病缺乏特征性体征及镜下表现, 诊疗较为困难。2022年4月郑州大学第一附属医院医学美容中心门诊收治1例通过浅表超声及症状初步诊断为表皮样囊肿感染的患者, 入院行手术切除后病理结果发现合并未分化多形性肉瘤, 予以肿瘤扩大切除术, 术后予以化疗, 随访8个月, 患者预后良好。该文通过详细回顾此病例的诊疗经过及对相关文献进行系统复习, 以期为皮肤未分化多形性肉瘤的诊疗提供参考。

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.
