RESUMO

Vitamin D receptor (VDR) is present in multiple blood cells, and the hormonal form of vitamin D, 1,25-dihydroxyvitamin D (1,25D) is essential for the proper functioning of the immune system. The role of retinoic acid receptor α (RARα) in hematopoiesis is very important, as the fusion of RARα gene with PML gene initiates acute promyelocytic leukemia where differentiation of the myeloid lineage is blocked, followed by an uncontrolled proliferation of leukemic blasts. RARα takes part in regulation of VDR transcription, and unliganded RARα acts as a transcriptional repressor to VDR gene in acute myeloid leukemia (AML) cells. This is why we decided to examine the effects of the combination of 1,25D and all-trans-retinoic acid (ATRA) on VDR gene expression in normal human and murine blood cells at various steps of their development. We tested the expression of VDR and regulation of this gene in response to 1,25D or ATRA, as well as transcriptional activities of nuclear receptors VDR and RARs in human and murine blood cells. We discovered that regulation of VDR expression in humans is different from in mice. In human blood cells at early stages of their differentiation ATRA, but not 1,25D, upregulates the expression of VDR. In contrast, in murine blood cells 1,25D, but not ATRA, upregulates the expression of VDR. VDR and RAR receptors are present and transcriptionally active in blood cells of both species, especially at early steps of blood development.

RESUMO

This review is inspired by a case of two pregnancies of the same patient complicated by HELLP syndrome, which suggests that there is a predisposition for the occurrence of preeclampsia and HELLP syndrome in early pregnancy. HELLP syndrome, uncommon below the 20th week and rarer still in two consecutive pregnancies, appeared in two pregnancies of the same woman. The aim of our work is to try to understand the cause of heterogeneity of HELLP syndrome and help find a way of prolonging such pregnancies. Recurrent HELLP syndrome in early pregnancy is a form of severe, fulminant preeclampsia. The preceding symptom is a surge in blood pressure. The hypertension becomes resistant to antihypertensive drugs, which indicates that preexisting hypertension is later accompanied by other factors contributing to the rise in blood pressure. Different effects of high dosage of corticosteroids on liver and platelets show that there are different factors responsible for liver damage and for thrombocytopenia. It seems that the symptoms have various origins, so the therapy with one drug only is not sufficiently effective. Nicotine analogues or a plant extract (from rootstock of Eriosema kraussianum) used by South African traditional healers for erectile dysfunction seem to give a chance of prolonging pregnancy and, consequently, having children.

RESUMO

PURPOSE: To determine, with extended receiver operating characteristic (ROC) curve analysis, the diagnostic value of cytokines showing significantly different peritoneal concentrations between women with and without endometriosis. METHODS: Multiplex cytokine concentration measurement of IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ levels in peritoneal fluid of women with minimal to mild (n = 10) and moderate to severe (n = 26) endometriosis, and 42 controls. RESULTS: Only IL-6 and IL-10 concentrations were significantly higher in endometriosis patients than in controls. Specifically, significantly higher IL-6 and IL-10 levels were found in moderate to severe but not in minimal to mild endometriosis as compared to controls. For evaluation of diagnostic significance, ROC analysis determined discriminating parameters for IL-6, while those calculated for IL-10 were useless. Importantly, ROC analysis for IL-6 levels limited to women with moderate to severe endometriosis showed the highest area under the curve with the sample size sufficient to achieve 90 % power of the test. Finally, extended ROC including cost of analysis for this group of patients determined the optimal cut-off leading to high specificity and positive likelihood ratio resulting in 79 % effectiveness of the test. CONCLUSIONS: While our outcomes show moderate usefulness of peritoneal IL-6 levels in discrimination of moderate to severe endometriosis, further studies might be needed to determine the usefulness of peritoneal IL-6 levels in detection of early stages of endometriosis, as such a finding would be more relevant in clinical decision making.

RESUMO

Meiosis arrest before fertilization is a common and unique feature of oogenesis in many animal species. On account of the unclear biological significance of meiosis arrest at various stages and for different durations in different animal species, this process and its regulation are the subject of many scientific studies. Studies on the development of ovarian teratomas proved to be helpful in defining the role of particular genes and biochemical cycles in control of the cell cycle in animals. These benign tumors are a valuable source of information on oocyte maturation. The c-mos proto-oncogene, which is specifically expressed in female and male germ cells, plays a crucial role in control of meiotic cell division in mammals. Its product--Mos protein kinase--acting through mitogen-activated protein kinases (MAPKs) regulates critical cellular functions required for homeostasis and decides about cell survival or apoptosis. The MAPK kinase kinase--MAPK kinase--MAPK (MKKK-MKK-MAPK) phosphorelay system, in view of its role in cells, seems to be the ideal target for therapeutic intervention in cancer and other diseases. The recent research on human oocytes suggests that the basic mechanisms regulating various stages of oocyte maturation are similar to those described in animals.

RESUMO

From the research point of view--ovarian teratomas, especially mature ones, are an interesting group of germ-cell tumors of the ovary. The WHO classification, which is not simple but includes all tumors that arise from germ cells, emphasizes the complexity of this group. Their complex pathophysiology is also very interesting from the clinical point of view because of their frequent occurrence,especially among young women of reproductive age. Mature ovarian teratomas are benign germ-cell tumors, but in rare cases, especially when they contain solid elements, peritoneal implants may be present which can stimulate malignant processes. Dermoid cysts, a subtype of ovarian teratomas, arise from totipotential germ cells and may therefore contain elements of all three germ layers, although ectodermal structures usually predominate. Radical surgical treatment is not necessity for this type of tumor because conservative surgery usually brings full recovery.However, they make perfect material for gaining interesting information regarding oocyte maturation and such critical cellular functions as proliferation, migration, differentiation, and apoptosis.There are still no unequivocal conclusions related to the role of mutation in genes which influence the mechanisms involved in control of the cell cycle and which may play important roles in the development of ovarian teratomas. In this review the roles of the Patched/Hedgehog and PI3K/Akt pathways and cyclin D protein in the neoplastic transformations of the germ cells are described.

RESUMO

OBJECTIVE: To investigate whether sphingosine analogues, which activate the ceramide signaling pathway to apoptosis, can cause the death of ectopic (EEC) and eutopic stromal endometriotic cells (EEU), as well as healthy eutopic stromal endometrial cells (HEU). DESIGN: The EEC, EEU, and HEU isolated from fertile and infertile women with endometriosis were cultured for 48 hours in RPMI medium with 10% fetal calf serum (FCS) and with 2.5-10 microM sphingosine analogues. SETTING: A clinic for the treatment of endometriosis and basic research laboratories. PATIENT(S): Nineteen women with follicular cyst and 16 women with endometriosis. MAIN OUTCOME MEASURE(S): The percentage of proliferating cells was determined by 93-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide (MTT) assay. Apoptosis and cell cycle were detected by fluorescence-activated cell sorter (FACS) Calibur flow cytometer. RESULT(S): The viability of EEC after exposure to 10 microM sphingosine analogues was 59.5% +/- 9.7% for D-sphingosine and 77.65 +/- 9.7% for DL-erythro-sphingosine, the viability of EEU was 69.2% +/- 14.2% and 42.0% +/- 15.5%, whereas the viability of comparative HEU was 9.0% +/- 4.8% and 18.8% +/- 8.3%, respectively. The differences were significant using the Mann-Whitney test. The apoptotic level of the cells treated with 10 microM sphingosine analogues for comparative HEU was 42.8% +/- 7.5% for D-sphingosine and 42.5% +/- 10.5% for DL-erythro-sphingosine, whereas for EEC this was 16.7% +/- 5.5% for D-sphingosine and 14.1% +/- 4.4% for DL-erythro-sphingosine and for EEU this was 14.3% +/- 4.7% and 22.9% +/- 8.9%, respectively. CONCLUSION(S): Ectopic and eutopic stromal endometrial cells from women with endometriosis have a damaged ceramide-downstream pathway to apoptosis.

RESUMO

INTRODUCTION: Vitamin D-binding protein (also called DBP or Gc-globulin) is recognized as a multifunctional protein involved in the action scavenger system, the transport of vitamin D sterols, and the modulation of immune and inflammatory responses. This study evaluated total serum and peritoneal concentrations of vitamin D-binding protein in women with endometriosis, known as an inflammation-associated disease. MATERIALS/METHODS: The total concentration of DBP was measured with an enzyme-linked immunosorbent assay (ELISA) using a polyclonal antibody raised in a goat immunized with human DBP. Serum and peritoneal fluid were collected from women with endometriosis (n=26) and from patients with benign gynecological conditions serving as a control group (n=17). RESULTS: In general, the vitamin D-binding protein concentration was higher in serum than in peritoneal fluid. Women with endometriosis had higher serum but lower peritoneal levels of DBP compared with the control group; however, no significance was noted. When the endometriosis group was divided with regard to severity, an insignificantly higher serum level of DBP was observed in advanced endometriosis compared with the mild form of the disease, whereas the peritoneal concentration was not dependent on disease severity. CONCLUSIONS: It is concluded that serum and peritoneal DBP concentrations are not affected in women with endometriosis; however, based on the latest published data, it is possible that both the serum and peritoneal concentrations of vitamin D-binding protein may be dependent on Gc genotype, which results in differential modulation of monocyte/macrophage activity.

RESUMO

Systemic changes related to cytokine expression levels in women with endometriosis remain a subject of controversy. There are many studies concerning this topic showing differential serum cytokine levels; however, there are limited data presenting cytokine expression at the single-cell level. This study focused on this question by measuring intracellular cytokine staining of activated peripheral CD3+ and CD14+ cells from women with endometriosis (investigative group) compared with those with uterine leiomyoma (control group). Isolated peripheral blood mononuclear cells from women with endometriosis and uterine leiomyoma were stimulated with PMA and ionomycin or with LPS to induce intracellular synthesis of TNF-alpha, IFN-gamma, and IL-8 in subpopulations of CD3+ cells and TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 in CD14+ cells. Comparison of the total groups of patients showed no significant differences in any of the intracellular cytokines investigated in the T cells and monocytes of women with endometriosis compared with controls. When the group of women with endometriosis was divided with regard to severity of disease, a significantly lower percentage of CD3+CD8- lymphocytes stained for IFN-gamma and a significantly higher percentage of CD14+ cells stained for MCP-1 in advanced endometriosis patients compared with the control group were observed. We conclude that peripheral mononuclear cells in women with advanced endometriosis may have differential cytokine synthesis in vitro. These results support the idea that differing immune cell activity measured by intracellular cytokine profiles in women with advanced endometriosis may be more a consequence of the disease than a cause.

RESUMO

OBJECTIVE: The pathogenesis of endometriosis is related to functional changes in CD3+ and CD14+ cells observed both at the local and systemic level. Here we investigated whether, and if so, how the body compartment influences cytokine expression in stimulated peritoneal and peripheral CD3+ and CD14+ cells of women with endometriosis. STUDY DESIGN: Isolated peripheral blood (PB) and peritoneal fluid (PF) mononuclear cells from women with endometriosis were cultured under non-adherent conditions and stimulated with PMA and ionomycin for 6h to induce intracellular cytokine synthesis of TNF-alpha, IFN-gamma, and IL-8 by CD3+ cells or with LPS for 9h to produce TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 by CD14+ cells. RESULTS: The percentages of positive CD3+ cells stained for TNF-alpha and IFN-gamma were significantly higher and those stained for IL-8 were significantly lower in PF compared with PB, this being independent of the stage of endometriosis. In contrast, the percentages of CD14+ cells producing TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 were significantly higher in PB than PF of women with endometriosis. CONCLUSIONS: Monocytes/macrophages and lymphocytes derived from the peripheral and peritoneal compartments of women with endometriosis differentially respond to stimulated cytokine synthesis induction. However, it is difficult to state whether the observed phenomenon is more related to body compartment influence per se or to the presence of endometriosis.

RESUMO

OBJECTIVE: To report a patient with bicornuate rudimentary uterine horns with functioning endometrium and complete cervical-vaginal agenesis coexisting with ovarian endometriosis. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 37-year-old woman with an extremely rare müllerian anomaly of the uterus and vagina coexisting with ovarian endometriosis. INTERVENTION(S): Resection of the rudimentary uterine horns with bilateral salpingo-oophorectomy. MAIN OUTCOME MEASURE(S): Relief from pelvic pain after the operative procedure. RESULT(S): The definite diagnosis and removal of the müllerian anomaly and endometriosis foci. CONCLUSION(S): Cyclic pelvic pain since the age of 14 was due to cryptomenorrhoea in the presence of the bicornuate rudimentary uterine horns with functioning endometrium and cervical-vaginal agenesis. Ovarian endometriosis developed as a result. In such cases, invasive procedures, such as laparoscopy or laparotomy, should be considered to establish the diagnosis. Removing the functioning rudimentary uterine horns just after menarche should prevent the development of endometriosis and hematometra.

RESUMO

The complicated process of invasion and metastasis consists of a long series of sequential and interrelated steps. The outcome of the process is dependent on both: the tumour cells and the properties of tissue microenvironments. Many investigators are interested in the influence of extracellular matrix components on that process. Especially matrix metalloproteinases (MMPs)--family of zinc-dependent enzymes, which take part in the coordination of extracellular matrix synthesis and breakdown seems to play crucial role in this process. A positive correlation between different type of MMPs and specific tumors has been demonstrated in many studies. In this article we summarize the current views on the role of MMPs in cancer invasion and metastasis.

RESUMO

It is essential for an embryo's further development that it generate a connection with the mother. The first stage of this process is implantation, a highly coordinated event that involves both embryonic and endometrial participation. A blastocyst may attach to the endometrium only during the "implantation window", when the uterus is receptive. A description of the molecular features of a receptive endometrium is the aim of this review. During the secretory phase, the endometrium synthesizes such cytokines as LIF (leukemia inhibitory factor), HB-EGF (heparin-binding epithelial growth factor), and TGF-alpha (transforming growth factor alpha) as well as special surface structures, such as integrins. There are two types of integrins: cycle dependent and constitutionally expressed. The coexpression of cycle-dependent integrins may mark the "implantation window". The endometrium of fertile and infertile women may vary in expression of the integrins. Insufficient synthesis of integrins may be caused by a luteal phase deficiency. E-cadherin and alpha-crystalin B play an important role during implantation. The expression of pinopodes on endometrial cells during the "implantation window" marks optimal uterine receptivity. The composition of all the factors mentioned above define the unique properties of the endometrium during the "implantation window".

RESUMO

Mycoplasmas comprise a big group of organisms consisting of one hundred eighty species which are found in nature as parasites of humans, other mammals, reptiles, fishes and plants, or living as commensals. The group commonly referred to as genital mycoplasmas comprise species most often found in the genitourinary tract of sexually active adults as common commensal inhabitants, or pathogens which can cause many different infections. The species we are most interested in this work are called: Mycoplasma genitalium, Mycoplasma hominis and Ureaplasma urealyticum. There is no doubt that they can cause non-gonococcal urethritis (NGU) in both men and women and bacterial vaginosis (BV), cervicitis, endometritis. Infection can spread to the upper port of female genital tract and it can lead to pelvic inflammatory disease, or if it happens during pregnancy--to chorioamnionitis and further pregnancy complications. Even though mycoplasmas have been known and described since 1898, the problem of their morbidity and the possible influence they have on human fertility is still not clear. Similar to research from 30 years ago, connecting Chlamydia trachomatis with infertility, new scientific work as well as the dynamic development of diagnostics procedure, especially more common use of PCR method, may be helpful in discovering the potential role genital mycoplasmas play in infertility.

RESUMO

INTRODUCTION: Vulvar cancer is very rare, accounting for about 3-5% female tract malignancies. Venereal diseases and cigarette smoking have been associated with vulvar cancer. Recently p53 gene mutation and Human Papilloma Virus (HPV) infections have been considered etiologic factors. DESIGN: The main aim of this study was the clinical analysis of patients with vulvar cancer treated in II Gynaecology Department of Medical University in Wroclaw. MATERIAL AND METHODS: We analyzed 25 women with vulvar cancer treated in our center. We focused on: choise of treatment, postoperative complications, p53 gene mutation, survival and recurrence of the disease. p53 gene mutations were detected using immunohistochemical methods with monoclonal Novocastra antibody (DO1). RESULTS: The youngest patient was 49 years old and the oldest 79 (median 70), 5 patients were younger than 60 (24%). 72% patients had overweight and 24% obese. The most often histopathological type was keratinizing squamous cell carcinoma. In 68% of cases vulvar cancer was detected in II, III or IVa stage according to FIGO classifications. In 24 patients we detected p53 gene mutation. 4 patients died because of cancer recurrence, 1 because of from radiotherapy complications. CONCLUSIONS: Obesity coexists with vulvar cancer. p53 gene mutation can be etiologic factor in vulvar cancer development. Metastases in inguinal nodes are an important prognostic factor in vulvar cancer.

RESUMO

Vulvar carcinoma accounts for 3-5% of all genital cancers. The most common histology of vulvar cancer is squamous cell carcinoma. It has been suggested that vulvar cancer exists as two separate diseases--HPV-positive, occurring in young women, and p53-positive, that occurs in older women. As extensive surgery resection is gold standard of treatment, it is important to play attention for all symptoms, suggesting the beginning of disease. Understanding of the anatomy and the mechanism of lymphatic spread have made modifications in surgical technique possible, allowing less radical excisions.

RESUMO

OBJECTIVE: To test whether serum monocyte chemotactic protein-1 (MCP-1) chemokine levels correlate with endometriosis in infertile women. STUDY DESIGN: A group of women with endometriosis (n = 18, infertile) was compared with patients with uterine leiomyoma (n = 16, fertile), unexplained infertility (n = 5, infertile), and healthy women (n = 16, fertile). MCP-1 expression levels were evaluated by ELISA assay. The data obtained were statistically analyzed using the Mann-Whitney test. P-Values <0.05 were considered as significant. RESULTS: MCP-1 concentrations (median; range of values) in serum were as follows: women with endometriosis (221; 101-635 pg/ml), women with unexplained infertility (167, 114-234 pg/ml), women with uterine leiomyoma (137; 88-200 pg/ml), and healthy donors (123; 98-194 pg/ml). Significant differences were observed in the women with endometriosis compared with those with uterine leiomyoma (p = 0.02) and healthy donors (p = 0.002). Among the women with endometriosis, the level of significance in MCP-1 level at rAFS stages III-IV was higher than that at rAFS stages I-II compared with healthy donors and women with leiomyoma (p = 0.002 and p = 0.02, respectively). CONCLUSIONS: These data show that an increased level of MCP-1 can characterize infertile women with endometriosis. However, further studies are needed to be able to determine whether increased MCP-1 chemokine expression can be related to infertility or is a result of endometriosis progress.

RESUMO

OBJECTIVES: Mycoplasma hominis and Ureaplasma species are common commensal inhabitants of the lower genitourinary tract in adolescents and adults who are sexually active. A lot of authors points out that these microorganisms can play an important role in pathology of genital tract like pelvic inflammatory disease, sterility or non-gonococcal urethritis. MATERIALS AND METHODS: In the study samples from cervical canal of the uterus were obtained from 222 women. The first group consist of 132 women who were examined in II Gynecological Clinic in Wroclaw for different, probably infectious, gynecological pathologies (adnexitis, sterility, bacterial vaginosis). 90 women without infectious diseases were in a control group. All swabs taken from cervix were tested for Mycoplasma hominis and Ureaplasma urealyticum. RESULTS: The prevalence of Ureaplasma urealyticum was 31.8% in the first tested group (42 of 132 women were positive) and 8.8% in control group (8 of 90 were positive). 3% (4 of 132) of patients were positive to Mycoplasma hominis in the first group and only 1.1% (1 of 90) in a control group. CONCLUSIONS: Ureaplasma urealyticum was found most often in such genital tract pathologies like acute or recurrent adnexitis, sterility or bacterial vaginosis. No statistically significant correlation was found between the age of the patients and the incidence of mycoplasmas.

RESUMO

PROBLEM: Interactions between the extracellular matrix (ECM) and peripheral blood T cells in women with endometriosis and leiomyoma are hardly unknown. We have investigated the influence of two major ECM components, collagen IV (C-IV) and fibronectin (Fn), on T-cell proliferation and apoptosis in women with endometriosis and uterine leiomyoma. beta1 integrin expression, responsible for interactions with ECM proteins, was also studied. METHOD OF STUDY: Peripheral blood lymphocytes were obtained from 53 women (17 with uterine leiomyomas, 18 with endometriosis, and 18 from healthy donors). T cells were exposed to ECM proteins co-immobilized with monoclonal antibody anti-CD3 for 72 hr. Apoptosis and S phase of the cell cycle of the T cells were studied by DNA analysis using flow cytometry. The proliferation of T cells was evaluated by MTT assay. The percentage of CD3+ cells expressing CD29 (beta1 integrin chain) was evaluated by double-color flow cytometry. Results were analyzed statistically using the Mann-Whitney test. RESULTS AND CONCLUSIONS: (1) A general increase in the percentage of T cells in S phase could be seen in women with endometriosis and uterine leiomyoma in all culture conditions what may suggest general activation of T cells. (2) A significant increase in the percentage of cells in S phase was shown only in the case of T cells exposed to anti-CD3 + C-IV in both women with uterine leiomyoma and endometriosis. (3) However, no apoptotic cells were observed. (4) T cells from patients with uterine leiomyoma exhibited significantly increased level of proliferation after culture with anti-CD3 + C-IV. (5) More T cells expressed beta1 integrin in women with endometriosis or uterine leiomyoma than in healthy donors. Our data may suggest that increased beta1 integrin expression may enhance T-cell-ECM interactions, which may be responsible for the increased proliferation of T cells but not for apoptosis. Therefore, it is possible that interactions of T cells with ECM proteins, especially with C-IV, may contribute to the pathogenesis of endometriosis and uterine leiomyoma.

RESUMO

BACKGROUND: The serum markers CA125, tissue polypeptide specific antigen (TPS), and soluble interleukin-2 receptor alpha (sIL-2Ralpha) concentrations were determined in sera, cyst, and ascitic fluids from patients with malignant and benign ovarian neoplasms. METHODS: CA125, TPS, and sIL-2Ralpha concentrations were measured in sera, cyst, and ascitic fluids by immunoassays in 67 patients with carcinoma and in 32 patients with benign ovarian neoplasms. RESULTS: CA125, TPS, and sIL-2Ralpha levels were elevated significantly in sera from patients who had ovarian carcinoma compared with patients who had benign neoplasms (P < 0.001). Patients who had International Federation of Gynecology and Obstetrics (FIGO) Stage III-IV disease had significantly higher serum levels for the markers studied compared with patients who had FIGO Stage I-II disease (P < 0.001 for CA125; P = 0.02 for TPS and sIL-2Ralpha). Concurrent measurement of CA125 and sIL-2Ralpha in sera identified 100% of ovarian carcinomas in FIGO Stage I-II. All patients with carcinoma demonstrated markedly higher levels of CA125 and TPS for both cyst and ascites compared with corresponding sera (P < 0.001). The level of sIL-2Ralpha was higher statistically in ascitic fluid compared with the level in serum (P < 0.001); however, its values in sera and cyst fluids were comparable. In ascitic fluid, the CA125 level was significantly higher in patients who had FIGO Stage III-IV disease compared with patients who had FIGO Stage I-II disease (P = 0.002), whereas such correlations were not found for TPS or sIL-2Ralpha. In cyst fluids, the levels of all studied markers were independent of the FIGO stage. In cyst fluids from patients with benign ovarian neoplasms, TPS and sIL-2Ralpha levels were significantly lower compared with the levels in patients with ovarian carcinoma (P < 0.001), whereas the values of CA125 were overlapping. CA125 and TPS concentrations were higher in cyst fluids compared with corresponding sera, whereas sIL-2Ralpha levels were comparable and low in cyst fluids and in the circulation of patients with benign neoplasms. CONCLUSIONS: In patients with ovarian carcinoma, TPS and CA125 concentrations were significantly higher in the place of their generation compared with the concentrations in blood circulation. sIL-2Ralpha values were higher in ascites compared with the values in corresponding sera, and its concentrations in sera and cyst fluids were comparable. The assessment of serum sIL-2Ralpha levels showed potential complementary value to CA125 for the detection of ovarian carcinoma in early FIGO stages; however, a 9% false positive rate limited the significance of cumulative value for a combination of these circulating markers.

RESUMO

Authors describe a case of choriocarcinoma with an atypical clinical course in 28-year old woman nine months after a normal pregnancy and labour. Diagnosis of the disease was very hard because endometrial biopsy did not show any suspected cells and two performed pregnancy tests were not positive. Diagnosis was confirmed after a hysterectomy. Authors conclude that every unclear vaginal bleeding during woman's reproductive years should be considered with a beta-HCG level measurement.
