Leiomyoma of the uterus ASSOCIATE PROFESSOR IOLANDA BLIDARU MD, PhD
Epidemiology • The commonest of all pelvic T. (1/3). • 20% of female > 35 years have fibroid. • Childbearing life. • Often enlarge during pregnancyor during oral contraceptive use, and regress after menopause • occurin women of reproductive age, often
Causes • Unknown • Hyperestrogenemia – E2 / ER, P / PR, GnRH, growth factors (IGF-1, EGF< PDGF< FGF) • Race • Obesity • Chromosomal abnormalities (7, 12, 14)
Pathology • MACROSCOPY • site • shape • size • consistency • cut section • capsule • number • varieties
Uterine leiomyoma • Cervical • 1-2% • solitary • Corporeal • 98% • multiple
Corporeal leiomyoma • submucus • 24% • not capsulated • Subserous • 18% • Interstitial • 58%
Cervical leiomyoma • Exocervix • small • sessile • polypoid • Supravaginal cervix • sessile • pedunculated
CONSISTENCY Firm Harder (hyaline degeneration). Soft (pregnancy-cystic degeneration). Stony hard (Calcification)
CUT SECTION • well demarcated surrounding muscle. • whorly (intermingling muscle fibers and fibrous tissue). • paler than surrounding (ischaemia).
Microscopic Examination • Few formed blood vessels (blood lakes). • Smooth muscle cells and fibrous tissue cells.
Changes occuring with fibroid General Genital tract Tumor itself
Genital tract • Endometrium - hyperplasia • Tubes - inflammation (salpingitis) • Endometriosis (30-40%)
Tumour itself • Benign degeneration • atrophic • hyaline • red • cystic • fatty • calcification • necrosis with or without infection • vascular (edema, lymphangiectasia) • Malignant degeneration (0.1-0.5 % - growth after menopause, rapid enlargement, recurrent fibroid polyp).
DIAGNOSIS • History • Examination. • Investigation. • D.D.
SYMPTOMS • No symptom • Bleeding (menorrhagia - metrorrhagia). • Pain - uncomplicated → congestion → dysmenorrhea; complicated → degeneration (malignant, infection, torsion) • Infertility • Mass • Discharge • Pressure symptoms (urinary, lower limb edema, constipation)
Signs • Symmetrically enlarged uterus • (submucosal fibroid) • Asymmetrically enlarged uterus(subserous fibroid)
Investigations • Clinical(examination) • Laboratory(Hb, Ht, urinary tests, pregnacy test, Pap test etc) • Imaging & instrumental techniques(US, hysteroscopy, hysterography, colposcopy, fractional curettage, Ct scan) • Miscellaneous(intravenous urography, etc)
DIFFERENTIAL DIAGNOSIS • Pregnancy (normal / abnormal) • Ademomyosis. Leiomyomas - myomectomy, adenomyosis - hysterectomy • Solid Adnexal Mass (fibromas, Brenner tumors, inflammatory mass) • Uterine Leiomyosarcoma ( histologically - the presence of infiltrativemargins, nuclear atypia, and increased mitotic figures )
No treatment Conservative Radiological Surgical GnRH agonists Uterine artery embolization. Patient (age, parity, symptoms). Tumor (number, size, type) Complications. Treatment of Leiomyoma
Treatment of Leiomyoma MEDICAL • Progesterone / Progestins • Selective PR modulator / antagonist(Mifepristone, Ulipristal) • GnRH agonists (Buserelin, Triptorelin, Leuprolid, Histerelin, Goserelin)
SURGICAL Myomectomy (Hysteroscopy, laparoscopy, laparotomy) Hysterectomy
