A subcutaneous mass in the left supraclavicular fossa of a 55-year-old woman proved on histological examination to be composed of islands of squamous cells embedded in bands of spindle cells and associated with mature adipose tissue. Electron microscopy showed that the spindle cells were fibroblastic in nature and not squamous cells showing spindle differentiation. There was also a minor lymphangiomatous component and sparse infiltrates of lymphoid cells. The lesion bore certain similarities to thymolipoma except that the presence of spindle cells and the site were atypical. While it may be speculated that the tumour was thymolipoma occurring in an ectopic cervical thymus the lesion is provisionally regarded as an unusual mixed tumour featuring mesenchymal and epithelial components.
一名55岁女性左锁骨上窝出现皮下肿物，组织学检查显示由嵌入梭形细胞带中的鳞状细胞岛组成，并伴有成熟脂肪组织。电子显微镜检查表明，梭形细胞本质上是成纤维细胞，而非显示梭形分化的鳞状细胞。此外还有少量淋巴管瘤成分以及稀疏的淋巴细胞浸润。该病变与胸腺脂肪瘤有某些相似之处，只是梭形细胞的存在及部位不典型。虽然可以推测该肿瘤是异位宫颈胸腺发生的胸腺脂肪瘤，但该病变暂被视为一种具有间充质和上皮成分的不寻常混合肿瘤。
