纤维性瘤

A core needle biopsy misdiagnosed PASH in 13 cases out of 28 cases and vacuum-assisted biopsy correctly identified PASH in all 3 cases.

4细胞性纤维腺瘤和囊肉瘤：PASH缺乏真正的间叶细胞过生长的现象，其细胞缺乏多形性，无核分裂象，也没有纤维腺瘤或囊肉瘤的上皮成分的生长类型。

Results 7of22cases were angiomyolipoma,6were xanthogranulomatous pyelonephritis,4were multilocular cystic nephroˉma,2were leiomyoma of kidney,2were renal abscess,one case were renal fibrolipoma.

结果 误诊为肾癌的良性占位病变22例，其中肾血管平滑肌脂肪瘤合并出血7例，局灶型黄色肉芽肿性肾盂肾炎6例，肾发性囊性肾瘤4例，肾平滑肌瘤2例，肾脓肿2例，肾纤维脂肪瘤1例。

Results All the 7 cases were female, 2 cases were solitary fibrous tumor, 2 cases were myofibroblastoma, 1 case was inflammatory myofibroblastic tumour, 1 case was fibromatosis, and 1 case was low grade myofibroblastic sarcoma.

结果 7例患者均为女性，2例为孤立性纤维性肿瘤；2例为肌纤维母细胞瘤；1例为纤维瘤病；1例为炎性肌纤维母细胞瘤；1例为低度恶性肌纤维母细胞肉瘤。

Methods Nuclear β-catenin expression was detected by immunohistochemistry in 77 lesions with desmoid-type fibromatosis and 171 other spindle cell lesions, including superficial fibrmoatosis (n=18), nodular fasciitis (n=36), keloid (n=16), scar (n=10), granulation tissue (n=9), synovial sarcoma (n=38), neufibroma (n=13), solitary fibrous tumor (n=12), gastrointestinal stromal tumor (n=10), low-grade myxofibrosarcoma (n=3), low-grade fibromyxoid sarcoma (n=3), and smooth muscle tumor (n=10). In addition, the immunohistochemical expressions of ER-α, ER-β and Ki-67 were examined in all of the lesions with desmoid-type fibromatosis. The nuclear immunohistochemical staining for nuclear βcatenin and ER-β was graded as high level (≥25% of cells), low level (5%-25%) or none.

采用免疫组织化学染色法检测77例韧带样型纤维瘤病和171例其它良、恶性梭形细胞病变（包括结节性筋膜炎36例、浅部纤维瘤病11例、瘢痕疙瘩16例、增生性瘢痕10例、肉芽组织9例、滑膜肉瘤38例、神经纤维瘤13例、孤立性纤维性肿瘤12例、胃肠间质肿瘤10例、低度恶性黏液纤维肉瘤3例、低度恶性纤维黏液样肉瘤3例及平滑肌肿瘤10例）组织中β-catenin核阳性的表达，同时检测韧带样型纤维瘤病中ER-α、ER-β和Ki-67的表达。

Objective To investigate the characteristics of bone benign fibrous histocytoma, nonossifying fibroma and metaphyseal fibrous defect.

目的 探讨骨良性纤维组织细胞瘤、非骨化性纤维瘤及干骺端纤维性缺损的特殊表现。

In the 25 patients with specimens suggesting fibroadenoma, excisional biopsy confirmed the diagnosis in 23 patients but revealed phyllodes tumor in two patients, yielding a negative predictive value of 93%.

建议为纤维性瘤的25名患者中，在23个患者中进行切除的组织切片检查而确认诊断，但是其中二名患者为叶状瘤，得到93%的阴性预测值。

From August 21, 1998, to December 14, 2001, 57 core needle biopsy specimens suggested the possibility of phyllodes tumor. Median patient age was 42 years (range, 16-77 years), and median lesion diameter was 1.1 cm (range, 0.6-3.6 cm). Of the 57 specimens, 25 had pathological findings favoring a diagnosis of fibroadenoma, 23 favored phyllodes tumor, and nine were equivocal.

从1998年8月21日至2001年12月14日，共有57个粗针切片检查样本显示出叶状瘤的可能性，这些患者年龄中位数为42岁（范围16-77 岁），病灶直径中位数为1.1 厘米（范围 0.6-3.6 厘米），在57 个样本中，25个的病理研究结果建议为纤维性瘤，23个为叶状瘤，其余的九个诊断的意义不明确。

For the 23 core biopsies suggesting phyllodes tumor, excisional biopsy confirmed the diagnosis in 19 but revealed fibroadenoma in four patients, for a positive predictive value of 83%. Final pathological analysis of the equivocal core biopsies diagnosed fibroadenoma in five patients and phyllodes tumor in four patients. Final analysis determined that none of the lesions were malignant.

23个核心组织切片检查建议为叶状瘤的患者，进行切除的组织切片检查后，确认了19名患者的检验结果，但是有4人为纤维性瘤，因此得到83%的阳性预测值，有歧异的粗针检查进行最后的病理分析后，发现五名患者为纤维性瘤，而四名患者为叶状瘤，最后的分析测定这些肿瘤都不是恶性的。

Sept. 11, 2003 Core needle biopsy helps differentiate phyllodes tumor from fibroadenoma, according to the results of a query of a radiology database published in the September issue of the Archives of Surgery . The authors suggest that this technique can signficantly reduce the need for surgery of fibroepithelial lesions.

Sept。 11， 2003-根据一篇发表於9月号Archives of Surgery的研究结果显示，粗针切片检查有助於自纤维性瘤区分出叶状瘤，作者建议，这种技术也可以明显地减少进行纤维上皮之病灶手术的需要。

Komenaka, MD, from Columbia Presbyterian Medical Center in New York City, and colleagues."Phyllodes tumors are uncommon enough to lack a well-defined, evidence-based diagnostic algorithm. Because of their clinical similarity to fibroadenoma, many are initially managed with enucleation, resulting in the frequent need for reoperation."

Komenaka博士表示，粗针切片检查可以在门诊时进行，其侵入性是最低限度的，而且费用上也具有应用可能性，以目前对叶状瘤的认识还不足能良好地辨别出来，因为它们与纤维性瘤在临床上是相似的，很多病例一开始进行肿瘤切除术，但是之后却还需要再进行手术。
