Five cases of an unusual pseudoangiomatous variant of spindle cell lipoma are presented. In keeping with more typical cases, these lesions occurred principally in the shoulder and neck regions of adult males. The lesions all had the features of typical spindle cell lipoma but, in addition, exhibited irregular and branching spaces with villiform connective tissue projections, giving a striking angiomatoid appearance. Although the pathogenesis is uncertain, this unusual histological pattern seems to be the result of myxoid degeneration and may lead to a mistaken diagnosis of a true vascular tumour or other non-lipomatous spindle cell lesion.
本文报告了5例梭形细胞脂肪瘤的一种不寻常的假血管瘤样变体。与更典型的病例一样，这些病变主要发生在成年男性的肩部和颈部区域。这些病变均具有典型梭形细胞脂肪瘤的特征，但此外，还表现出不规则且分支的间隙以及绒毛状结缔组织突起，呈现出显著的血管瘤样外观。尽管发病机制尚不确定，但这种不寻常的组织学模式似乎是黏液样变性的结果，可能会导致对真正的血管肿瘤或其他非脂肪瘤性梭形细胞病变的误诊。
