脂肪母细胞瘤 (ｌｉｐｏｂｌａｓｔｏｍａ)属于错构瘤(ｗｉｌｌｉｓ) ,为幼稚的脂肪母细胞在局部增生形成 ,脂肪母细胞来源于临近小血管的内皮细胞 ,细胞中聚集有小颗粒脂滴 ,核大居中 ,随着细胞的发育脂滴变大占据细胞的主要部分 ,核变小偏离中心 .脂肪母细胞瘤临床上发生于颈 Lipoblastoma belongs to hamartoma (willis), which is formed by local hyperplasia of immature fat mother cells. The fat mother cells are derived from endothelial cells adjacent to small blood vessels. Small lipid droplets accumulate in the cells, and the nucleus is in a large center. With the development of cells, lipid droplets become larger and occupy the major part of the cell, and nuclear degeneration is off-center. Lipoblastoma occurs clinically on the neck.
