皮囊肿

Results: 4 cases were geminoma, 3 cases were teratoma, 1 case was choriocarcinoma, 4 cases were glioma, 2 cases were meningiomas, pineoblstoma, neuroblastoma, dermoid cyst and arachnoid cyst each had one case. It maybe very difficult if we diagnosed only through MR signals. Due to the multitude origin of histology, we can diagnose through some special signals, such as adipose, cystic degeneration, hemorrhage and implant dissemination. We can also combined with clinical examination which is help to differential diagnosis.

The five most common benign lesions were dermoid cyst and epidermoid cyst, cavernous hemangioma, lymphangioma, pleomorphic adenoma, orbital inflammation. The five most common malignant lesions were lymphoma, lacrimal adenoid cystic carcinoma, rhabdomyosarcoma, melanoma, sebaceous gland carcinoma.

位于良性病变前5位的分别是皮样囊肿及表皮样囊肿、海绵状血管瘤、淋巴管瘤、泪腺混合瘤、慢性炎症和炎性假瘤；位于恶性肿瘤前5位的分别是淋巴瘤、泪腺囊腺癌、横纹肌肉瘤、黑色素瘤、皮脂腺腺癌。

Results Among 85 cases, 46 cases were lipomas, Twenty-seven cases were sebaceous cysts, 19 cases were angeiomas, 8 cases were fibroids, 5 cases were ganglionic cysts, 3 cases were neurilemmomas,1 case was dermal nevus, 1 cases was fattey necrosis, 1 case was adipositis, 1 case was foreign-body granuloma,1 case was calcified epithelioma.

结果 85例中脂肪瘤46例，皮脂腺囊肿27例，血管瘤19例，纤维瘤8例，腱鞘滑液囊肿5例，神经鞘膜瘤3例，皮肤痣、脂肪坏死、脂膜炎、异物肉芽肿、钙化上皮瘤各1例。

Results MMP-2 positive cells are localized in peripheral columnar while no positive cells are seen in odontogenic karatocysts and dentigerous cysts.

结果 成釉细胞瘤中MMP-2阳性染色位于肿瘤外周柱状细胞的胞浆中，中心星网状细胞未见表达；角化囊肿和含牙囊肿的上皮细胞中均未见MMP-2的阳性表达。

Methods Epithelial cells and fibroblast from ameloblastoma, keratocyst, dentigerous cyst, radicular cyst and oral mucosa were cultured and observed by phase-contrast microscope.

原代体外培养成釉细胞瘤细胞、牙源性角化囊肿、根端囊肿及口腔粘膜的上皮细胞和成纤维细胞，倒置光相差显微镜观察。

Most lesions of SD including bony deformities could be diagnosed with MRI. But the differential diagnosis of epidermoid between dermoid was still difficult.

MRI能正确、全面地诊断包括椎体畸形在内的大多数脊柱神经管闭合不全病变，但表皮样囊肿和皮样囊肿的鉴别仍存在困难。

Methods: Twenty-nine patients under 1 year with choleduchal cysts were reviewed between 2000 to 2006. The expressions of CD4, CD8, CMV and EBV were detected by immunohistochemical staining for observing the distribution of choleduchal epithetical cells. The information combined with clinical data and operative cholangiogram were analyzed.

回顾性分析我院2000年－2006年收治的1岁以下的胆总管囊肿29例，采用免疫组化技术分别检测CD4、CD8、CMV、EBV在胆总管囊肿上皮细胞中的表达情况，并结合术中造影检查分析。

Results Among 85 cases, 46 cases were lipomas, Twenty-seven cases were sebaceous cysts, 19 cases were angeiomas, 8 cases were fibroids, 5 cases were ganglionic cysts, 3 cases were neurilemmomas,1 case was dermal nevus, 1 cases was fattey necrosis, 1 case was adipositis, 1 case was foreign-body granuloma,1 case was calcified epithelioma.

回顾性分析85例体表良性肿块的超声表现，总结其声像图特征，所有病例均经手术病理证实。结果 85例中脂肪瘤46例，皮脂腺囊肿27例，血管瘤19例，纤维瘤8例，腱鞘滑液囊肿5例，神经鞘膜瘤3例，皮肤痣、脂肪坏死、脂膜炎、异物肉芽肿、钙化上皮瘤各1例。

Rathke cleft cysts are benign epithelium-lined intrasellar cysts believed to originate from remnants of the Rathke pouch.

Rathke囊肿是一种良性的上皮细胞囊肿，据信是起源于Rathke囊的残余。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
