Lipomas are one of the most common benign tumors, but deep tissue and huge lipomas are rare.
A 59-year-old middle-aged woman was admitted to hospital for right hip mass resection because of numbness and pain in her right lower limb for 6 months. Ultrasound and nuclear magnetic resonance imaging (MRI) showed irregular mass. On the assumption of malignancy, the patient underwent a right hip mass resection and returned to normal with no short-term or long-term response. HE (hematoxylin-eosin) staining of the tumor showed the characteristics of a benign tumor.
The pathogenesis of myolipoma is not clear, and it may be related to brown adipose tissue. When lipoma is huge, it needs interventional treatment. Complete encapsulated myolipoma can usually be completely removed, with low recurrence possibility and good prognosis.
Giant intramuscular lipoma of hip and its clinical manifestations are relatively rare. And the results of ultrasound imaging are similar to those of the surrounding normal adipose tissue. No significant difference was observed by naked eye. In particular, postoperative pathological examination is needed to make a definite diagnosis and differential diagnosis. Clinically, surgical treatment is often used, and the prognosis is good, but recurrence is possible. The following report discusses the experience of one of our patients, with literature review.
脂肪瘤是最常见的良性肿瘤之一,但深部组织脂肪瘤和巨大脂肪瘤较为罕见。
一名59岁中年女性因右下肢麻木和疼痛6个月入院,接受右髋部肿物切除术。超声和核磁共振成像(MRI)显示肿物不规则。考虑为恶性,患者接受了右髋部肿物切除术,术后恢复正常,无短期或长期不良反应。肿瘤苏木精-伊红(HE)染色显示为良性肿瘤特征。
肌脂肪瘤的发病机制尚不清楚,可能与棕色脂肪组织有关。脂肪瘤巨大时需要进行介入治疗。完全包膜的肌脂肪瘤通常可以完全切除,复发可能性低,预后良好。
髋部巨大肌内脂肪瘤及其临床表现相对罕见。超声成像结果与周围正常脂肪组织相似。肉眼观察无明显差异。特别是需要术后病理检查进行明确诊断和鉴别诊断。临床上常采用手术治疗,预后良好,但可能复发。以下报告讨论了我们一名患者的经验,并进行文献复习。
