RESUMO

This is a single tertiary population-based study conducted at a center in southwest Romania. We retrospectively compared data obtained in two periods: January 2008-December 2013 and January 2018-December 2023. The global incidence of the transposition of great arteries in terminated cases, in addition to those resulting in live-born pregnancies, remained almost constant. The live-birth incidence decreased. The median gestational age at diagnosis decreased from 29.3 gestational weeks (mean 25.4) to 13.4 weeks (mean 17.2). The second trimester and the overall detection rate in the prenatal period did not significantly change, but the increase was statistically significant in the first trimester. The proportion of terminated pregnancies in fetuses diagnosed with the transposition of great arteries significantly increased (14.28% to 75%, p = 0.019).

RESUMO

Endometrial polyps (EPs) are a frequent gynecological condition. EPs often arise in the common womanly patients and are appraised to be about 25%. Advancing age, hyperestrogenism, hypertension, and Tamoxifen use are acknowledged as ordinary risk elements for the development of EP. The etiopathogenesis of EP is not accurately elucidated, but certain considerations such as diabetes mellitus, hormonal factors or arterial hypertension are considered to perform a significant contribution. The diagnosis of EPs is essentially by imaging. Transvaginal ultrasound is the primary investigation in EPs. Hysteroscopic resection is now the "gold standard" to treat to treat this disease. Hysterectomy is the definitive treatment for EPs, but it requires a judicious indication and an adequate counseling of the patient. Currently, a certain histological pattern is found in different sequences in EPs. Even if the vast majority EPs are benign, they may reach hyperplastic, with malignant alteration. The purpose of this pictorial review is the integrated approach to this type of abnormal endometrial proliferation from the perspective of natural history, diagnosis, management, morphological aspects, risk of malignancy, recurrence and last but not least, clinical outcome.

RESUMO

Malignant mixed mesodermal sarcomas (myxoid leiomyosarcomas - MLMS) are a rare form of uterine cancer developed from the smooth muscles of the uterus. It usually affects women in the postmenopausal period and has an aggressive character with an unfavorable evolution and prognosis. This paper presents a case where MLMS was postoperatively confirmed with the aid of the histopathological (HP) examination coupled with specific immunolabeling techniques. In addition, we reviewed modern literature to compare our results. Clinically, patients may present with a pelvic tumor, vaginal bleeding, or abdominal pressure. Imagistic investigations, such as pelvic ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT may support the diagnosis. Nevertheless, solely the HP examination establishes it. Macroscopically, MLMS is soft and gelatinous, unlike the conventional rigid and spiral leiomyoma appearance. Furthermore, the infiltrative, irregular tumor margin is characteristic of MLMS. From a microscopic point of view, the following are present: tumor cell necrosis, nuclear pleomorphism, and variable mitotic activity. With classical Hematoxylin-Eosin (HE) staining, myometrium presents a leiomyomatous structure and multiple nodular formations with the aspect of malignant tumor proliferation, most likely mesenchymal. We used multiple special immunolabeling techniques. Thus, we observed the intense reactivity of the cells to the anti-vimentin antibody, which immunolabeled type III intermediate filament (IF) protein expressed in mesenchymal cells, thus demonstrating tumor mesenchymal affiliation. Smooth cell positivity for alpha-smooth muscle actin (α-SMA) demonstrates that the tumor is present in its whole myometrial structure. Tumor cells also underwent mutations involving the p53 tumor suppressor gene demonstrated by the number of tumoral cells in division immunolabeled with anti-Ki67 proliferation antibody. Tumor development was demonstrated by protein activation of cyclin-dependent kinase (CDK) and the presence of c-Kit-bound hematopoietic stem cells, immunolabeled with the anti-cluster of differentiation 117 (anti-CD117) antibodies. The anti-desmin antibody demonstrates, along with α-SMA, the involvement of myocytes in the tumoral process. The following microscopic characteristics laid the foundation for the diagnosis of MLMS: irregular myometrial invasion, rare mitosis on high-power fields (HPFs), cell pleomorphism, predominant myxoid component that gave a hypocellular appearance, the matrix rich in proteoglycans and glycosaminoglycans, especially hyaluronic acid.

RESUMO

Our communication presents a prenatally detected case with severe spinal defect detected in the first trimester of pregnancy, accompanied by a large skin-covered myelomeningocele but normal cranio-cerebral structural appearance.These findings suggest that in the first trimester, the extent of the spinal defect, the cerebrospinal fluid leakage to a large, but skin-covered, meningocele and fixation of the spinal cord at the lesion are not sufficient to determine downward hindbrain displacement and the development of secondary signs for open spina bifida.Therefore, we suggest a careful evaluation of the fetal cerebral features if a meningocele is detected. The presence of the skin covering the lesion may not be evident in the first trimester, but the absence of intracranial open spina bifida markers may indicate a 'closed' spinal defect, which generally associates a good neurological outcome. Also, studies aimed to investigate the accuracy of the intracranial features for open spina bifida detection should consider the possibility of 'closed' myelomeningoceles to avoid incorrect correlations.

RESUMO

Adenomyosis is a benign pathology, common to both women at reproductive age as well as later during menopause. This condition is accompanied by a strong symptomatology, which has induced intense research on this topic. From a morphological point of view, it is represented by the existence of endometrial glands and, sometimes, of the periglandular stroma (endometriosis) in the structure of the myometrium, at a significant distance from the normal endometrium. Various inflammatory, vascular and mechanical factors accentuate the symptoms and evolution of this pathology. Our study included a total number of 32 patients, eight cases for each of the following histopathological subtypes: endometrium - proliferative phase, endometrium - secretory phase, myometrium with endometrial glands (adenomyosis), and myometrium with hyperplastic transformation of endometrial glands (hyperplastic adenomyosis), respectively. We have conducted clinical, morphological and morphopathological studies of the structures in question. Using the classical histological technique (Hematoxylin-Eosin), we identified the glandular structures; utilizing immunohistochemistry, we have labeled the endometrial epithelium with the anti-cytokeratin 7 (CK7) antibody and we analyzed the periglandular cell types of the immune system: T-lymphocytes using anti-cluster of differentiation (CD) 3 antibody, macrophages using anti-CD68 antibody, mast cells using anti-tryptase antibody, periglandular vascularization with the reaction using anti-CD34∕anti-CD31 antibodies, thus demonstrating their involvement in the development of adenomyosis. The interesting aspect of this study is the technique of simultaneously labeling of the inflammatory, vascular and epithelial elements.

RESUMO

OBJECTIVES: To assess the ultrasound (US) impact in diagnosing placenta accreta (PA) in patients with anterior placenta praevia localization, overlying a Caesarean scar. PATIENTS, MATERIALS AND METHODS: This is a prospective study between January 2016 and December 2017 that included patients with Caesarean scar and placenta praevia in the third trimester of pregnancy. By means of two-dimensional (2D) grayscale and color Doppler, we investigated the presence of the following US markers for placental invasion: intraplacental lacunae, abnormal blood vessels at the myometrium-bladder interface, thinning of the hyperechogenic uterine serosa-bladder wall interface, loss of normal hypoechoic retroplacental myometrial space. Definitive diagnosis was made at delivery. The US findings were correlated with intraoperative and histopathological (HP) evaluations. RESULTS: We found 46 cases with anterior placenta praevia overlying a Caesarean scar. Twelve patients presented US criteria for PA. The confirmation was obtained (by means of intraoperative and/or HP features) in 11 of them. The US evaluation with all markers yields a sensitivity of 100% for PA detection. Among the US markers, the association of abnormal blood vessels at the myometrium-bladder interface and the intraplacental lacunae had the highest statistical correlation in the antenatal diagnosis of PA. CONCLUSIONS: Our study suggests that the antenatal US is a useful tool in predicting PA in high-risk patients. Special attention should be given to the presence of intraplacental lacunae and abnormal myometrial vessels in cases where the placental insertion overlaps a uterine scar for best identification of PA high-risk cases.

RESUMO

The incidence of multiple pregnancy has significantly increased over the past decades, reaching different statistics to double, triple, or even overcome these numerical orders globally. Zygosity and chorionicity are the key elements in the multiple pregnancy but the placentation issue should be correlated primarily with zygosity, unlike chorionicity that should be correlated with the outcome and complications of multifetal gestation. Multiple pregnancy is by itself a special maternal-fetal condition, and the monochorionic one, moreover, due to specific complications. These aspects make early assessment of chorionicity and amnionicity a priority. Ultrasound is essential in pregnancy but pathological placental examination after delivery is complementary, in order to have a complete overview of potential mechanisms and pathogenesis affecting twin gestation. In this review, we highlight both ultrasound aspects specific to multifetal placentation, complemented by macro and microscopic morphological aspects, which underpin the obstetric imaging.

RESUMO

Endometriosis is a benign pathology, commonly found in women at reproductive age. It is represented by the ectopic presence of the endometrial glandular epithelium in several tissues and organs. This ectopically located tissue can display premalignant or even malignant changes under the influence of certain factors that affect cell structure, function and proliferation. Our study includes a total of 28 patients, with endometriosis of different localizations: ovarian or pelvic endometriosis, adenomyosis or endometriosis of the abdominal wall. We performed a clinical and statistical analysis upon the collected clinical and laboratory data, together with the results obtained by using classical histological and immunohistochemical (IHC) profiling. The classical staining revealed the existence of the ectopic glandular epithelium, while the IHC reactions obtained with the anti-cytokeratin (CK) 7∕anti-CK20, anti-estrogen receptor alpha (ERα)∕anti-progesterone receptor (PR) antibodies, ascertained that these tissues were of endometrial origin. The environmental, hormonal or inflammatory factors influence these areas, so that the ER∕PR scores may be modified, the cellular proliferation might be increased (Ki67+ marker), the anti-apoptotic B-cell lymphoma 2 (BCL2) protein expression and phosphatase and tensin homolog (PTEN) may also be modified. Moreover, tumor protein 53 (p53) was positive in cases with atypia, density of inflammatory cells clearly increased compared to the adjacent normal endometrium, respectively with cluster of differentiation (CD) 3+, CD20+, CD68+, CD79a+, and tryptase+ cells, all of which may influence the cellular structure, histological architecture of the surrounding microenvironment and cause premalignant or even malignant changes in endometriosis outbreaks.

RESUMO

The single stillbirth long-term intrauterine retention in dichorionic twin pregnancy is rarely reported. Also, the birth of a fetus is followed in most cases by immediate expulsion of the second twin. We hereby present an unusual case of asynchronous delivery of dichorionic twins, associating discordance for major and minor anomaly. The intrauterine death of the twin A, presenting a large sacrococcygeal tumor, occurred in the second trimester. The deceased twin A was born at 29 weeks' gestational age (GA). The twin B was extracted by Caesarean section at 31 weeks and had a good outcome. We performed a close follow-up of the high-risk pregnancy and we used tocolytic and antibiotic drugs for prolonging it. Corticoid therapy was administered for the lung maturation of the second twin. The expectant management in the single twin stillbirth dichorionic pregnancy and the asynchronous delivery had a significant impact on the newborn outcome.
