皮样囊肿属于良性畸胎瘤类型,Black Well氏将100例皮样囊肿作多次(10—15次)切片检查,发现其中100％有外胚叶组织,93％有中胚叶组织,71％有内胚叶组织;唐敏一等氏据56个皮样囊肿的详细切片检查,100％有外胚叶成分,80.4％有中胚叶成分.44.6％有内胚叶成分,所以我们似乎可以说,皮样囊肿是一种外胚叶组织占主要成分的先天性、良性、囊性肿瘤。一般认为皮样囊肿,为在胚胎形成的早期,某部细胞受内外在因素的影响,而引起一部细胞与该组织脱离,脱离的某部细胞如仍在适宜生长及繁殖的条件下,即可逐渐发育成人体某部组织或器官。
Dermoid cysts are of the benign teratoma type, and 100 cases of dermoid cysts were examined multiple times (10-15 times) by the Black Wells, and 100% had epiblast tissue and 93% had mesodermal tissue. 71 % of endoderm tissue; Tang Minyi, etc. According to detailed examination of 56 dermoid cysts, 100% have ectodermal composition, 80.4% have mesodermal composition, and 44.6% have endoderm composition, so we seem to It can be said that the dermoid cyst is a congenital, benign, cystic tumor that is the main component of the epiblast tissue. Dermoid cysts are generally considered to be affected by internal and external factors in the early stage of embryogenesis, causing a cell to detach from the tissue, and a cell that is detached is still under conditions suitable for growth and reproduction. Can gradually develop an adult body tissue or organ.
