    Abstract:
    Leiomyomatosis peritonealis disseminata (LPD) is a rare disease, which is most often found in women in reproductive age - seldom pre- and postmenaupausal. LPD has been described in women taking oral contraceptives or during pregnancy. LPD is mostly asymptomatic and discovered during operations like section caesarea, etc. Because of the macroscopic aspect (multiple small nodules <2 cm) a metastasing tumour is suspected during operation. These nodules consist of smooth muscle fibres and show benign histologic features. An increased level of cases with similar endometriosis (10%), myoms of uterus or functional ovarian tumours have been reported. Few cases of malignant transformation have also been described. In the pathogenesis of LPD a metaplastic change of submesothelial multipotential mesenchymal cells as an abnormal response on hormonal stimulation is debated. A regression of LPD after delivery or after stopping oral contraceptives is possible. Another therapeutic option is the application of GnRH-agonists. We present a case of a 35-year old female patient with sudden abdominal pain and suspicious findings in abominal ultrasound and CT-abdomen. The intraoperative aspect shows diffuse intraabdominal nodules consisting of smooth muscle fibres and a cystic left ovary. LPD, endometriosis and a borderline lesion of the left ovary were diagnosed by intraoperative histological examination. A bilateral salpingo-oophorectomy and omentectomy were performed.
