上皮囊肿

Results Of 80 cases 46 were acoustic neuromas (57.5%), 15 meningiomas (18.5%), 6 epidermoid cysts(7.5%), 5 trigeminal neuromas (6.3%) and 8 other rare tumors(10%).

结果 80例肿瘤中，听神经瘤46例(57.5%)，脑膜瘤15例(18.8%)，上皮样囊肿6例(7.5%)，三叉神经瘤5例(6.3%)及其它少见肿瘤8例(10%)。

Results Microscopically, the tumor cells were epithelioid or short spindled and special nests of tumor cells separated by arboring fibrovascular septa. Such morphological variants of CCSK as myxoid degeneration, microcysts formation and sclerosing pattern of extracellular hyalined collagen simulating osteoid were present in some regions.

结果 镜下见瘤细胞为上皮样或短梭形，被分枝状纤维血管间质分隔成巢团状，部分区域见黏液样变性微囊肿和细胞外胶原玻璃样变类似骨样组织的硬化型等形态变异。

A mucocele is a ball of concentrated mucus surrounded by a layer of pseudo-stratified columnar epithelium. It gradually grows and slowly expands in a paranasal sinus cavity, and even erodes the adjacent structures. Most paranasal sinus mucoceles occur in the frontal and ethmoid sinues. Mucoceles are usually unilateral, and are rarely bilateral (4%).

鼻窦黏液囊肿是鼻窦黏液被伪复层柱状上皮(pseudostratified columnar epithelium)所局限，在鼻窦内逐渐成长与扩张，甚至侵犯到邻近的结构，好发於额窦及筛窦，且多为单侧病灶，双侧较为少见(4%)。

However, odontogenic tumors or cysts may originate from residual cells, although little is known about how HERS proliferates and disappears.

虽然对于HERS细胞的增殖及消失了解甚少，但牙源性肿瘤或囊肿可能起源于上皮剩余。

Multiple familial trichoepithelioma is inherited in autosomal dominant manner with high penetrance. The involvement of MFT in woman is more than that in man. Multiple lesions commonly present small tumors located predominantly in the nalolabial folds symmetrically. Most of the tumors are dome-shaped, skin-colored, firm

总之，毛发上皮瘤是一种高度外显的常染色体显性遗传病，女性发病多于男性，以沿鼻唇沟对称分布的乳白色半球形或圆锥形丘疹为皮损特征，无恶化趋势，组织病理为角质囊肿与肿瘤岛，同一家系中不同的患者表现度不同

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
