背部弹力纤维瘤误诊为脂肪瘤的原因分析OA

Objective To investigate the clinical manifestations,diagnostic principles,and therapeutic approaches for elastofibroma dorsi(ED),to analyze the causes of misdiagnosis as lipoma at initial diagnosis.Methods A retrospective analysis was conducted on the clinical data of a patient with ED that was misdiagnosed as lipoma in Zibo Central Hospital in April 2025.A comprehensive analysis was conducted based on relevant imaging findings and both domestic and international literature,and to propose strategies for preventing misdiagnosis along with surgical management recommendations,ultimately enhancing clinicians'understanding of this disease,and reducing the misdiagnosis rate.Results The patient was admitted to the hospital with the chief complaint of a subcutaneous mass on the back detected for one week.At the initial diagnosis,based on the patient's medical history,physical signs,and relevant imaging examination results,it was diagnosed as lipoma,and subsequently underwent excision of the subcutaneous mass on the back combined with pedicled composite tissue flap plasty.After the routine postoperative pathological examination and immunohistochemical results,it was finally confirmed as ED,with a misdiagnosis duration of 7 d.The wound healed well after surgery and the patient was discharged smoothly.After 6 months of postoperative follow-up,the wound healed well,with no signs of ulceration or recurrence.Conclusion ED is a rare benign soft tissue tumor-like lesion in clinical practice.Its clinical manifestations lack specificity,making it prone to misdiagnosis.For middle-aged and elderly patients,especially women,when a mass occurs in the infrascapular region of the back,it is necessary to maintain a high level of vigilance.Due to the strong subjectivity of ultrasound examination,the key to preventing misdiagnosis is to promptly perform high-resolution CT or magnetic resonance imaging examinations to identify characteristic imaging findings such as the striated sign.
