Liposarcoma arising within a phyllodes tumor is extremely rare. To the best of our knowledge, a malignant phyllodes tumor with liposarcomatous stroma diagnosed by fine needle aspiration (FNA) has not been reported before.
A 39-year-old female had a malignant phyllodes tumor with liposarcomatous stroma diagnosed by FNA cytology. Two subtypes of liposarcomatous stroma, including lipomalike differentiated and myxoid, were found in the aspirates. The cytologic findings were very representative of the histologic features.
It is very important to recognize the cytologic features of such rare tumors. An accurate diagnosis preoperatively by FNA permits better therapy planning.
叶状肿瘤内发生的脂肪肉瘤极为罕见。据我们所知，此前尚无通过细针穿刺抽吸（FNA）诊断出具有脂肪肉瘤样间质的恶性叶状肿瘤的报道。
一名39岁女性经FNA细胞学检查诊断为具有脂肪肉瘤样间质的恶性叶状肿瘤。在抽吸物中发现了脂肪肉瘤样间质的两种亚型，包括脂肪瘤样分化型和黏液样型。细胞学表现非常典型地反映了组织学特征。
认识此类罕见肿瘤的细胞学特征非常重要。术前通过FNA进行准确诊断有助于制定更好的治疗方案。
