Intravascular fasciitis is a special type of nodular fasciitis. It is an uncommon lesion. We report here the first case of intravascular fasciitis involving the deep muscle of the hip joint. The female, postpartum patient presented with a large, firm, painless tumoral mass in the anterolateral muscles of the right hip. The diagnosis of intravascular fasciitis was difficult because of the large size and location of the lesion. The false positive immunohistochemistry for MUC4 initially caused our team to misdiagnose the intravascular fasciitis as a low grade malignant fibromyxoid sarcoma. Our case adds to the literature on intravascular fasciitis. Since the operation about 20 months prior, the tumor in this case has not recurred.
血管内筋膜炎是结节性筋膜炎的一种特殊类型。它是一种罕见的病变。我们在此报告首例累及髋关节深层肌肉的血管内筋膜炎病例。该产后女性患者右侧髋部前外侧肌肉出现一个大的、质地坚硬、无痛的肿瘤性肿块。由于病变的大小和位置，血管内筋膜炎的诊断较为困难。MUC4的假阳性免疫组化结果最初导致我们团队将血管内筋膜炎误诊为低级别恶性纤维黏液样肉瘤。我们的病例丰富了血管内筋膜炎的文献资料。自约20个月前手术以来，该病例中的肿瘤未复发。
