Ultrastructural study of a case of benign lipoblastomatosis revealed a cellular spectrum which included undifferentiated mesenchymal cells, stellate myxoid cells, fibroblasts, lipoblasts, lipocytes and many intermediate forms. The uni- and multivacuolated fat cells contained membrane and non-membrane bound cytoplasmic vacuoles, predominatly of saturated lipid. Their cytoplasm also contained simple-structured mitochondria devoid of intramatrical or crystalloid bodies. The fine structure of the cellular components of lipoblastomatosis supports the concept that this is a neoplasm related to fetal white fat rather than to brown fat.
一例良性脂肪母细胞瘤的超微结构研究显示，细胞谱系包括未分化间充质细胞、星状黏液样细胞、成纤维细胞、脂肪母细胞、脂肪细胞以及许多中间形态。单泡和多泡脂肪细胞含有膜性和非膜性结合的细胞质空泡，主要为饱和脂质。其细胞质还含有结构简单的线粒体，无基质内或晶体样小体。脂肪母细胞瘤细胞成分的精细结构支持这样一种概念，即这是一种与胎儿白色脂肪而非棕色脂肪相关的肿瘤。
