卵巢畸胎瘤是什么样子的呢?What does ovarian teratoma look like?

陈凤林教授指出：卵巢畸胎瘤通常由2-3个胚层构成。成熟性囊性畸胎瘤表面光滑、包膜完整，直径10cm左右。囊内含有皮脂和毛发，有时可见牙齿、骨骼和头皮构成的头节，头节突向腔内为其特征。

Professor Chen Fenglin pointed out that ovarian teratomas usually consist of 2-3 embryonic layers. Mature cystic teratoma has smooth surface and complete envelope with a diameter of about 10 cm. The capsule contains sebum and hair. Sometimes the scalp ganglion composed of teeth, skeleton and scalp can be seen, which is characterized by the protrusion of the scalp ganglion into the cavity.

未成熟畸胎瘤的分化程度不一，显示了各胚层从未成熟向成熟阶段衍化的过程，组织学形态从癌到肉瘤，各种成分混杂。含神经成分的畸胎瘤归为未成熟畸胎瘤。

The degree of differentiation of immature teratomas is different, which shows the process of embryonic development from immature stage to mature stage. Histological morphology of immature teratomas ranges from cancer to sarcoma, and various components are mixed. Teratomas containing nerve components are classified as immature teratomas.
