Lipoblastomas are most commonly superficially-located tumors. Our experience with three examples of deep-seated lipoblastomas is reported. The CT scans of all cases showed low-attenuation densities (less than 0 Hansfield units), strongly suggesting fatty composition. Fine-needle aspiration biopsy (FNAB) smears contained uni- and multivacuolated lipoblasts, myxoid areas, and a plexiform capillary network. The combination of CT scan and FNAB findings seems to be enough for definitive preoperative diagnosis of lipoblastoma, allowing differential diagnosis with other deep-seated tumors.
脂肪母细胞瘤最常见于浅表部位的肿瘤。本文报道了我们对3例深部脂肪母细胞瘤的诊治经验。所有病例的CT扫描均显示低密度影（小于0亨氏单位），强烈提示含有脂肪成分。细针穿刺活检（FNAB）涂片可见单泡和多泡脂肪母细胞、黏液样区域及丛状毛细血管网。CT扫描和FNAB检查结果相结合似乎足以对脂肪母细胞瘤进行术前确诊，并可与其他深部肿瘤进行鉴别诊断。
