And the most common benign tumor in human body 是女性生殖系统最常见的良性肿瘤, 并且是人体最常见的良性肿瘤 Present in 20-25% of reproductive-age women 发生于20-25%的生育年龄妇女,病 因 Aetiology,High concentrations of both estrogen and progesterone receptors 肌瘤组织中含有高浓度的雌、孕激 素受体,分类 Classification,According to the location,Myoma is divided into: Uterine body myoma (90%) Cervical myoma (10%),依据肌瘤的位置分类: 子宫体肌瘤(90%) 子宫颈肌瘤(10%),分 类 Types,各型子宫肌瘤示意图,肌 壁 间 肌 瘤 (intramural myoma),Within the uterine wall 肌瘤位于子宫肌壁内，周围均被肌层包围。 占6070,浆 膜 下 肌 瘤 (subserous myoma),Deforming the external serosa 肌瘤向子宫浆膜面生长，突起在子宫表面， 约占20%,浆 膜 下 肌 瘤,Extend between the 2 peritoneal layers of the broad ligament 若肌瘤位于宫体侧壁向宫旁生长，突阔韧带两 叶之间称阔韧带肌瘤,阔韧带肌瘤 Broad ligament myoma,阔韧带肌瘤 Broad ligament myoma,粘 膜 下 肌 瘤 (submucous myoma),Deforming the uterine cavity 肌瘤向子宫粘膜方向生长,突出于宫腔,仅由粘膜层覆盖,占10-15%,粘 膜 下 肌 瘤,多发性子宫肌瘤 (multiple myomata ) 子宫肌瘤常为多个性,各种类型的肌瘤可发生在同一子宫，称多发性子宫肌瘤,多 发 性 子 宫 肌 瘤,white-colored, round, smooth, and usually firm, pseudocapsule 呈白色的,圆形的,光滑的,并且常是 坚硬的,有假包膜,病 理 Pathology,漩涡状 whorled appearance 纤维结缔组织 Fibrous connective tissue,sarcomatous change 肉瘤变,Degeneration 肌瘤变性,cystic degeneration 囊性变,red degeneration 红色变,Hyaline degeneration 玻璃样变,with calcification 钙 化,透明样变 Hyaline degeneration,The most common degeneration 最普遍的变性 Its whorled structure disappears and is replaced by clear substance, white color 螺旋状结构消失,由透明结构代替,呈白色 Under microscope, the cells in the degeneration area disappear 镜下观,变性区域细胞消失,囊性变 Cystic degeneration,Secondary change following hyaline degeneration 紧随透明样变性的次级变化 Tissue necrosis and liquefaction and forms multiplecysts 有组织坏死、液化和形成多发囊性结构,红色变 Red degeneration,Whorled structure disappears and has bad smell 螺旋结构消失和有恶臭 Most common during pregnancy and puerperium 最常见于妊娠期和产褥期 It is a special type necrosis which cause is not clear 为一种特殊类型的坏死,原因不明 Accompanied by pain and fever and rapidly enlarged myoma 伴随有疼痛,发热和肌瘤迅速增大,肉瘤变 Sarcomatous change,Malignant transformation of leiomyoma 子宫肌瘤的恶性转变 The frequency is 0.4-0.8%,often occurs in old women 发病率为0.4-0.8%,多见于老年妇女 The myoma enlarges rapidly in short term with irregular vaginal bleeding 肌瘤短期迅速增大并伴有不规则阴道流血,钙化 Degeneration with calcification,Majority occur in the myomas with thinpedecle or after menopause 多发生于蒂小或绝经后肌瘤 Causes precipitation of calcium carbonate and phosphate 引起碳酸钙和磷酸盐的沉积 Often secondary to the fatty degeneration 常发生于脂肪变之后,脂 肪 样 变,临 床 表 现,症 状 Symptoms Depend on their location, the speed of growth and degenerations 取决于肌瘤部位、生长速度及肌瘤变性 It is not associate with the size and the number of myomas 与肌瘤大小、数目无关,Abnormal Menstrual bleeding,体 征 Signs Relate to myoma size 、location 、number 、 degeneration 与肌瘤大小、位置、数目以及有无变性有关,Diagnosis according to typical symptoms and signs 、 Ultrasound 、 Hysteroscopy and Laparoscop,诊 断 根据典型的 症状和体征、 超声、 宫腔镜及腹腔镜,治 疗 Treatment,Depends on the patients age 、parity 、 symptoms 、 myoma size 根据患者年龄、产次、症状、肌瘤大小等情况全面考虑 Follow up every 3 to 6 months 每36个月随访一次,药 物 治 疗 androgenic hormone 雄激素 GnRH 促性腺激素释放激素类似物,手 术 治 疗 surgery Myomectomy 肌瘤切除术 Hysterectomy 子宫切除术,子 宫 肌 瘤 合 并 妊 娠 Myomas during pregnancy,Produce uterine inertia, fetal malpresentation, or obstruction of the birth canal 产生子宫无力,胎先露异常,或者产道阻塞 May necessitate cesarean delivery 有可能进行剖宫产 Interfere with effective uterine contraction after delivery 干扰分娩后子宫的有效收缩 The possibility of postpartum hemorrhage 有产后出血的可能,课 堂 讨 论 Questions,What are the operation indication of uterus myoma?
