摘要
目的：探讨乳腺分叶状肿瘤（PTB）的临床及超声表现。方法：回顾性分析10例经手术、病理证实的PTB患者的临床和乳腺超声影像资料。结果：患者均为女性，年龄21～59 岁，病程1周～5年。首发症状为乳腺无痛性肿块。所有肿块触诊质地坚韧，表面光滑，可以活动。乳腺超声检查共显示瘤体10个，多位于乳腺外上象限（7/10）。所有肿块按超声声像图不同表现分为3个类型：其中分叶形6个，圆形、椭圆形或呈浅分叶状的3个，不规则形状1个（内部呈囊实混合性）。肿块直径1.5～9.5cm。按WHO分类标准，其中良性6例，交界性2例，恶性2例。多数交界性和恶性PTB的彩色多普勒血流分级多为II级和III级。肿块内均未见钙化灶，未见异常血管图像，无邻近组织结构紊乱及腋下淋巴结肿大。结论：PTB在临床及超声影像表现上与纤维腺瘤有很多相似之处，但在中年妇女乳腺发现较大肿块且短期内迅速长大并结合一些特征性的超声声像图应高度怀疑PTB可能。
Abstract
Objective: To study the ultrasonic characteristics and clinical features of the breast phyllode tumor(PTB). Methods: Clinical and imaging findings were retrospectively reviewed in 10 cases with 10 phyllode tumors identified at preoperative ultrasonography. Results: All patients were female, age ranged from 21 to 59 years old, each of them had a history ranged from 1 week to 5 years. Painless breast lump was the common presentation. On clinical examination, all lumps were firm and mobile. Ultrasonography display 10 lumps and the upper outer quadrant was the most commonly involved site(7/10). The ultrasonic characteristics of images were divided into three types, their shape including lobulated(n=6), round and oval(n=3), irregular in shape(n=1, as mixed echoes of cystic and solid). The tumor diameter varied between 1.5cm and 9.5cm. According to the histologic criteria of WHO, of all the cases, 6 were benign PTB, 2 cases were borderline and 2 cases were malignant PTB. Most of the borderline and malignant PTB showed blood flow grade II~III. Endotumoral calcifications and secondary sign of malignancy were absent. Conclusion: Although many of the phyllode tumors are indistinguishable from fibroadenoma on the basis of clinical and ultrasonic characteristics, in large breast tumors with rapid growth, and show typical ultrasonic characteristics, the tentative diagnosis of phyllodes tumors should be considered.
