Value of early pregnancy ultrasound combined with ultrasound score in the evaluation of placenta accreta in scar uterus: A retrospective cohort study.

The objective of this study is to investigate the value of early pregnancy ultrasound combined with ultrasound score (USS) for the evaluation of placenta accreta (PA) in scar uteri. Thirty cases of PA in scar uteri diagnosed by ultrasound at our hospital between June 2021 and June 2022 were selected retrospectively (observation group). In addition, 30 patients had placenta attached to the anterior wall of the uterus and covered the internal orifice of the cervix; however, no PA was selected in the same period (control group). The results of surgical pathology and ultrasound examination in the first trimester of pregnancy (11-14 weeks of pregnancy, fetal top hip length 4.5-8.4 cm) were analyzed. Ultrasonic image characteristics of the 2 groups were scored using an ultrasonic scoring scale. The ultrasonic signs and ultrasonic scores of the 2 groups were analyzed. The diagnostic value of ultrasound and USS for PA in the scarred uterus alone and in combination was analyzed based on the gold standard of surgical and pathological results. The rich blood flow signal at the junction of the uterine serosa and bladder, the rate of blood flow in the cavity of the placental parenchyma, the thinning rate of the myometrium after placenta, and the abnormal rate of the low echo area after placenta in the observation group were significantly higher than those in the control group (P < .05). The USS of the observation group was significantly higher than that of the control group (P < .05). The sensitivity (93.33%) and accuracy (95.00%) of the combined examinations were significantly higher than those of ultrasound (70.00% and 83.33%, respectively) (P < .05). The sensitivity and accuracy of combined examination were slightly higher than those of USS examination (83.33% and 90.00%), but the difference was not statistically significant (P > .05). There was no significant difference between the specificity of combined examination (93.33%) and ultrasound (96.67%) and USS (96.67%) (P > .05). Early pregnancy ultrasound and USS evaluation have high application value in the diagnosis and evaluation of early scar uterine PA. The combination of the 2 methods can further improve the sensitivity and accuracy of diagnosis.

Recurrence complicated with peritoneal dissemination after single-port gasless myomectomy for cellular uterine leiomyoma: A case report and literature review.

RATIONALE: Cellular uterine leiomyomas (CL) represent the prevailing subtype among uterine leiomyomas. In this study, we report a case of recurrent peritoneal disseminated uterine fibroids 2 years after single-port laparoscopic gasless myomectomy. This article endeavors to examine the potential limitations of the aforementioned surgical procedure and outline the distinguishing features of recurrent cases with primary postoperative pathology as CL. Additionally, it aims to provide a summary of previous retrospective studies on CL and propose the existence of immunohistochemical molecules that may serve as predictors for the postoperative recurrence of cellular uterine fibroids. The ultimate objective is to enhance clinicians' comprehension of the disease. PATIENT CONCERNS: Two years ago, the patient underwent a single-port gasless laparoscopic myomectomy for uterine fibroids. Gynecological color Doppler ultrasound conducted 3 months ago revealed recurrence of uterine fibroids, and the patient experienced abdominal distension, mild urinary frequency, and constipation for the past month. DIAGNOSES: After the second surgical procedure, a comprehensive pathological examination and immunohistochemical analysis of both the uterine mass and metastatic lesions revealed that the definitive diagnosis was CLs. INTERVENTIONS: The patient underwent the total hysterectomy, bilateral salpingectomy, pelvic adhesiolysis, omental mass resection, mesenteric mass resection, and pelvic peritoneal mass resection. All specimens were sent for rapid frozen examination and showed to be leiomyomas. OUTCOMES: The patient was discharged from the hospital on the 10th day after the operation. At the date of writing the article, the patient had no recurrence for 1 year and 5 months. LESSONS: The single-port gasless approach did not achieve the desired reduction in fibroid recurrence, as anticipated by the surgeon. The act of pulling the tumor towards the abdominal incision for resection, on the contrary, may serve as an iatrogenic factor contributing to postoperative recurrence of CL into peritoneal dissemination leiomyomatosis. The single-port gasless assisted bag may be a more suitable option for myomectomy. The utmost effort should be made to prevent the potential recurrence of myoma caused by iatrogenic factors.

Mature solid teratoma of the uterine cervix: A rare case report and review of the literature.

RATIONALE: Most of the mature teratomas are found in the ovaries. Extragonadal teratomas are extremely rare. To date, there are only a handful of reports of uterine cervical teratomas documented in the English literature. PATIENT CONCERNS: Herein we describe a rare case of a 40-year-old patient who was presented to our hospital for a cervical polypoid mass, which was finally confirmed to be mature solid teratoma in uterine cervix. DIAGNOSES: Histological examination of the polypoid mass was found to consist of ciliated pseudostratified columnar respiratory epithelium, intestinal epithelium and smooth muscle tissue, adipose tissue and mature glial component, epidermis, and skin adnexa. Meanwhile, no history of abortion, dilatation, and curettage was present in this patient, so implantation of fetal tissue was excluded. Therefore, we make a diagnosis of uterine cervical mature teratoma. INTERVENTIONS: Tumorectomy was performed after discovering the cervical polypoid mass. OUTCOMES: The patient had been followed-up for next 3 months after surgery and no recurrence was documented until now. LESSONS: Though teratomas of the uterine cervix are extremely rare, more attention should be paid on this rare but possible tumor for appropriate treatment in these patients.

Microbial responses and changes in metabolic products in bovine uteri infected with Staphylococcus aureus.

There is mounting evidence that the uterine microbiota has an important role in the pathogenesis of endometritis, with invasion of pathogenic bacteria being a main cause of uterine microbial imbalance. However, mechanisms of uterine microbiota resistance to pathogen invasion remain unclear. In this study, an intrauterine infusion of Staphylococcus aureus was used as a bovine endometritis model; it significantly increased abundance of pathogenic bacteria (Streptococcus, Helccoccus, Fusobacterium, and Escherichia-Shigella) and significantly decreased abundance of probiotics (Allstipes, Bacteroides, Phascolarctobacterium, Romboutsia, and Prevotella). In addition, the metabolite aloe-emodin was positively correlated with Prevotella and based on combined analyses of omics and probiotics, the presence of its metabolite aloe-emodin in the uterus at least partially resisted Staphylococcus aureus invasion. Therefore, Aloe-emodin has potential for regulating microbial structure and preventing endometritis.

Spontaneous regression of a giant uterine leiomyoma after delivery: a case report and literature review.

BACKGROUND: Uterine leiomyomas are hormone-dependent benign tumors and often begin to shrink after menopause due to the reduction in ovarian steroids. The influence of pregnancy on uterine leiomyomas size remains unclear. Here, we present a case of spontaneous regression of a giant uterine leiomyoma after delivery. CASE PRESENTATION: A 40-year-old woman presented with multiple uterine leiomyomas, one of which is a giant uterine leiomyomas (approximately 8 cm in diameter) that gradually shrinked after delivery. At over two months postpartum, the large myometrial leiomyoma had transformed into a submucosal leiomyoma, and over 3 years postpartum, both the submucosal leiomyoma and multiple intramural leiomyomas completely regressed. CONCLUSION: Spontaneous regression of a giant uterine leiomyom is rare after delivery. Considering uterine leiomyoma regression until over 3 year postpartum,we need to observe the regression of uterine fibroid for a longer time postpartum in the absence of fibroid related complications. In addition, it will provide new insights for treatment options of uterine leiomyomas in the future.

Clinicopathological features of two ultra-rare cases of malignant perivascular epithelioid cell tumors (PEComas) involving the uterus with recent updates.

Malignant perivascular epithelioid tumors (PEComas) involving the uterus are uncommon. Herein, we present the clinicopathological features of two such cases, including their diagnostic implications with recent updates. A 62-year-old lady presented with vaginal bleeding. Ultrasonogram revealed a heterogeneous uterine mass. She underwent an endometrial biopsy and total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH-BSO), which revealed a 3.2 cm-sized proliferative tumor in the fundus. A 45-year-old lady presented with recurrent abdominal pain. She underwent cytoreductive surgery twice with adjuvant chemotherapy for multiple tumors and TAH-BSO for a uterine tumor, 2 years before. Microscopic examination of both tumors revealed markedly atypical, polygonal-shaped/epithelioid tumor cells containing eosinophilic cytoplasm and arranged in a nesting pattern with intervening thin-walled blood vessels, mitotic figures (≥ 6/10 high power fields (hpfs)), and tumor necrosis. Tumor infiltration was more than half the myometrial thickness in the first tumor and pelvic nodal metastasis. The second tumor revealed rhabdoid-like and vacuolated cells along with "spider-like" giant cells. Immunohistochemically, both the tumors were positive for HMB45 and desmin, while negative for epithelial markers. Additionally, the second tumor was positive for smooth muscle actin (SMA) and TFE3. Both patients developed tumor recurrences. In view of multiple tumor deposits, the second patient was induced with a mammalian target of rapamycin (m-TOR) inhibitor (everolimus) but unfortunately died of the disease. Malignant PEComas involving the uterus are ultra-rare, aggressive tumors. An index of suspicion, based on certain histomorphological features, supported by immunohistochemical expression of myomelanocytic markers is necessary for a correct diagnosis. Certain PEComas display TFE3 positivity. A correct diagnosis has significant implications, including an aggressive clinical course and the possibility of targeted therapy, especially in recurrences or metastasis.

A morphological study of symptomatic uterine niche using three-dimensional models from thin-slice magnetic resonance imaging.

RESEARCH QUESTION: Is there a correlation between various morphological parameters of the uterine niche and post-menstrual spotting using three-dimensional models from thin-slice (1 mm) magnetic resonance imaging (MRI)? DESIGN: This study retrospectively identified women diagnosed with a symptomatic niche by thin-slice MRI between December 2019 and December 2021. Univariable and multivariable linear regression models assessed the correlations between morphological parameters and the duration post-menstrual spotting. Morphological differences of the niche formed by one versus two Caesarean sections were analysed by univariable and multivariable logistic analysis. RESULTS: A total of 205 women diagnosed with symptomatic niche were included in the study. The niche among most women with post-menstrual spotting was ellipsoidal, with width greater than length greater than depth, from which niche volume was estimated based on manual measurements (volume = 0.520 × length × width × depth). Manually calculated niche length (ß = 0.257, 95% confidence interval [CI] 0.040-0.473, P = 0.020) and radiomically assessed minor axis length (ß = 0.329, 95% CI 0.009-0.795, P = 0.045) both positively correlated with the duration of post-menstrual spotting, whereas the distance between the niche and external os (ß = -0.120, 95% CI -0.202 to -0.038, P = 0.004) was inversely correlated. Women with two Cesarean sections reported more days of post-menstrual spotting (8.76 ± 3.54 versus 6.68 ± 3.90 days, P < 0.001) and had increased niche length diameter (adjusted odds ratio [aOR] 1.304, 95% CI 1.190-1.429) and a smaller surface-area-to-volume ratio (aOR 0.296, 95% CI 0.129-0.680). CONCLUSIONS: Niche-associated post-menstrual spotting correlates with the length diameter of the niche and the distance between the niche and external os. Niches in women after two Caesarean sections tend to be longer in length diameter and more spherical.

COL1A1::PDGFB fusion-associated uterine fibrosarcoma: A case report and review of the literature.

BACKGROUND: Mesenchymal neoplasms of the uterus encompass a diverse group of tumors, with varying characteristics and origins, collectively accounting for 8% of uterine malignancies. The most common variants include uterine leiomyosarcoma, low-grade and high-grade endometrial stromal sarcoma, adenosarcoma, and undifferentiated sarcoma. Clinical presentation is often nonspecific and can lead to delayed diagnosis. Uterine sarcomas are generally aggressive, resulting in poorer prognosis compared to carcinomas. Recent advances in molecular techniques, such as next-generation sequencing (NGS), have led to the identification of new subtypes of uterine sarcomas, including COL1A1::PDGFB fusion-associated fibrosarcoma, which has a specific chromosomal translocation t(17;22)(q22;q13). Imatinib, a tyrosine kinase inhibitor (TKI), is an effective treatment for dermatofibrosarcoma protuberans (DFSP), marked by this translocation. CASE: We present the case of a 42-year-old woman diagnosed with COL1A1::PDGFB fusion-associated uterine fibrosarcoma. The patient underwent total hysterectomy and excision of the tumor, initially misdiagnosed as a low-grade leiomyosarcoma. Subsequent histological examination, immunohistochemistry, and fluorescence in situ hybridization (FISH) confirmed the diagnosis. After 10 months, disease recurrence was detected, and Imatinib therapy was initiated at a dose of 400 mg daily. An allergic reaction led to a temporary discontinuation, but upon resumption with appropriate medication, a positive radiological response was observed. The patient achieved a complete remission after 2 years and is still on Imatinib treatment. CONCLUSIONS: COL1A1::PDGFB fusion-associated uterine fibrosarcoma is an extremely rare mesenchymal neoplasm. In a case we present herein, we treated a patient with imatinib as first-line medical therapy. The patient is currently in complete remission after 37 months from treatment start. To the best of our knowledge, this represents a unique observation. We also provide a detailed literature review of the published cases so far. Prospective case series are needed to further understand the natural history of these tumors and optimize treatment strategies.

Serum miRNA Combined With Transvaginal Color Doppler Ultrasound Diagnosis Clinical Research on Cervical Cancer.

OBJECTIVES: To explore clinical value of miRNA-18a, miRNA-130a, and miRNA-92a combined with transvaginal color Doppler ultrasound (TVCDS) in the diagnosis of cervical cancer (CC). METHODS: One hundred patients with pathologically confirmed CC (CC group), 100 patients with cervical epithelial neoplasia (disease group), and 100 patients with benign uterine lesions (control group) were selected. TVCDS was performed, and the levels of serum miRNA-18a, miRNA-130a, and miRNA-92a were detected. RESULTS: The systolic blood velocity of the cancer group, the disease group, and the control group decreased sequentially, while the resistance index and pulsatility index increased sequentially. The serum miR-18a, miR-130a, miR-92a, and expression levels of the patients' increased sequentially. Multivariate logistic regression analysis showed that age, high-risk human papillomavirus (HR-HPV) infection, menopause, blood flow RI, serum miRNA-18a, miRNA-92a, and miRNA-130a were the influencing factors of CC. The receiver operating characteristic curve showed that the sensitivity, specificity, accuracy, and area under curve of transvaginal Doppler ultrasound in the diagnosis of CC were 86.43%, 88.01%, 84.32%, and 0.913; serum miR-18a were, respectively, 76.56, 81.30, 80.36, and 0.839; serum miR-130a were 77.88%, 76.97%, 78.32%, and 0.0.864; serum miR-92a were 71.04%, 80.39%, 80.74%, and 0.894; 90.33%, 95.14%, 91.25%, and 0.947, the area under curve of the combined detection of the 3 was greater than that of the single detection. CONCLUSIONS: Serum miRNA combined with TVCDS has the advantages of it being noninvasive, and having high sensitivity and high specificity in the diagnosis of CC.

Placenta Accreta Spectrum: Evaluation of classic and non-classic presentations, pathologic grading, and uterine scar dehiscence features in a modern institutional series.

INTRODUCTION: The aim of this study is to document the distribution of classic versus non-classic presentation of Placenta Accreta Spectrum (PAS) disorders as well as grading categories by the Society for Pediatric Pathology (SPP) and FIGO systems in an institutional cohort of gravid hysterectomies. We also document the prevalence of uterine scar as a histologic correlate for uterine scar dehiscence, a phenomenon raised by some as central to PAS pathogenesis. METHODS: PAS cases were assigned grade and designated as classic (anterior lower uterine segment implantation, prior C-section) or non-classic (implantation away from anterior lower uterine segment and/or no prior C-section). Features of dehiscence (uterine window, histologic evidence of scar) were recorded. RESULTS: Sixty-two patients were included: 76 % had prior C-section; 55 % had other forms of uterine instrumentation. Classic PAS was recorded in 52 % patients; notably, 48 % had non-classic presentation; of these, all but one had prior instrumentation (curettage, myomectomy, laparoscopy). Uterine window was described in 53 % classic and 23 % non-classic PAS. Scar was demonstrated in 31 % classic and 23 % non-classic PAS; trichrome/reticulin stains were confirmatory. 32 % cases were SPP grade 1, 18 % grade 2, 18 % grade 3a and 32 % grade 3d. Grade 3 was significantly more common in classic (72 %) than non-classic (27 %) PAS. DISCUSSION: While most PAS patients have classic presentation, a large subset does not; in addition, scar tissue is not identified histologically in most PAS hysterectomies; in these settings, PAS cannot be fully attributed to scar dehiscence. Uterine instrumentation often precedes non-classic PAS reinforcing the concept of decidual disruption as central to PAS pathogenesis. PAS grading as defined correlates with presentation (classic vs non-classic).

Retrospective analysis of uterine involvement in low grade serous ovarian carcinoma.

OBJECTIVES: Low grade serous ovarian carcinoma (LGSOC) accounts for 2.5% of all ovarian carcinoma more affects younger women than high grade serous ovarian carcinoma. Hysterectomy is performed routinely for LGSOC treatment, but fertility sparring surgery (FSS) is feasible for some early stages. Currently, there is no study about uterine involvement in LGSOC. We evaluate uterine involvement in LGSOC patients and aim to identify pre-operative predictive factors. METHODS: Retrospective observational study of LGSOC patients treated between January 2000 and May 2022 in the Hospices Civils de Lyon. All cases were viewed, reviewed or approved by an expert pathologist. RESULTS: Among 535 serous ovarian carcinomas, 26 were included. Most patients (73 %) had FIGO III disease. Median OS was 115 months and median PFS was 42 months. Uterine involvement was found in 58 % patients who underwent hysterectomy (14/24), serosal involvement was the most frequent type of involvement (n = 13, 54 %). Myometrial involvement was found in 8 patients (33 %) and was associated with serosal involvement (7/8). Among patients with a macroscopic disease-free uterus during exploratory laparoscopy, 31 % had a microscopic serosal involvement. None patient with presumed early stage (FIGO I) were upstaged due to uterine involvement (serosal or myometrial). In patients with stage FIGO IIII, 72 % of uterine involvement were found. Univariate analysis did not show any predictive factor of myometrial involvement. There was no difference on OS nor PFS between patients with or without myometrial involvement. CONCLUSIONS: In early stages LGSOC, FSS may be considered for selected patients. In advanced stages, hysterectomy should be performed routinely, since no predictive factor for uterine involvement were identified.

Targeting inflammation for the treatment of endometritis in bovines.

The uterine endometrial surface of bovines is in constant exposureconstantly exposed with to a multitude ofmany microbial populations that changes throughout the post-partum phase in terms of complexity and dynamics. These microbes contribute to the host pathology, leading to severe economic losses along withnd reproductive capabilities. The basic primary interface that occurs between the internal tissues of the body of the hostbetween the host body's internal tissues and the microbes is the endometrial surface of the uterus. As a result of the infinite pathogenic population, there is always a danger for the opportunistic organisms to attack. Therefore, it is paramount that any interactions, especially microbial microbes with the endometrial surface, are regulated by the host cells. However, the inflammatory response as the defense mechanism contributes a pivotal roleis pivotal in host immunity and pathology. The inflammatory cascade and pathways are important essential to eliminate this clinical problem. In this review, we will discuss and explain how the inflammation and the various components of the immune system play their role in host pathology and therapeutic strategies, taking into account the interface between the host and the microbes on the surface of the endometrium. This review is also instrumental in further explanation of inflammatory uterine disease by discussing the response of inflammation to external insult.

Implication of biosignatures in the progression of endometriosis.

Endometriosis is an estrogen-dependent chronic inflammatory disorder involving the placement and growth of endometrial tissue outside the uterine cavity. It is the most common multifactorial disease that affects the life quality of women in reproductive age. Due to its multicomponent nature, early diagnosis of the disease is challenging. Since many genetic, epigenetic alterations and non-genetic factors contribute to the pathology of endometriosis, devising a drug therapy that directly acts on the ectopic tissue is extremely difficult. Endometriosis is a hormone-driven disease with estrogen considered as a primary driver for the development of endometriotic lesions. This study aims to identify biosignatures involved in endometriosis with and without gonadotropin releasing hormone agonists (GnRHa). GnRHa is a short peptide analog of GnRH that causes inhibition of estrogen and androgen synthesis. Microarray based-gene expression profiling was performed on total RNA extracted from endometriotic tissue samples with and without GnRHa-treated patients already published in our previous paper. The untreated group were considered as the control. Genes were then selected for validation by quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR analysis confirmed significant downregulation in(p < 0.05) expression of DARC (p = 0.0042), CDH1 (p = 0.0027), CDH5 (p = 0.0283), ATP2A3 (p < 0.001), RGS5 (p = 0.0032), and CD36 (p = 0.0162) in endometriosis patients treated with GnRHa analogs. Although, CTNNAL1 (p = 0.0136) also showed significant results but there was upregulation in their expression levels after GnRHa treatment. Thus, an altered expression of these genes makes them a possible candidate determinant of endometriosis treated with GnRHa.

Endometrioid carcinomas with sex cord-like formations and hyalinization: spontaneous pregnancy after conservative treatment.

Endometrioid carcinoma with sex cord-like formations and hyalinization of the uterine corpus, or corded and hyalinized endometrioid adenocarcinoma (CHEC), is a rare morphological variant of endometrioid carcinoma, for which there is limited literature and few cases reports. Most researchers tend to consider CHEC as a low-grade cancer with a favorable prognosis. Full-staging surgery is the primary choice for this disease, and no case of CHEC has been previously reported to be treated conservatively. Here, we present the following case to explore the possibility of fertility-preserving treatment for young women with CHEC. A 23-year-old nulliparous patient diagnosed with presumed stage IA CHEC received fertility-sparing treatment at the Obstetrics and Gynecology Hospital of Fudan University and got a complete response (CR) after 10 months of conservative treatment. The patient subsequently became pregnant spontaneously, successfully conceived, and gave birth to a healthy male neonate without any sign of recurrence during 37 months follow-up after CR. The patient's postpartum follow-up is continuing. Presently, CHEC is not included in the fertility-sparing field of any available guidelines. This case indicates that fertility-sparing treatment may be an option for highly selected patients with CHEC. Continuous follow-up remains mandatory to observe long-term outcomes.

Comparison of perioperative surgical outcomes between contained and free manual vaginal morcellation of large uteruses following total laparoscopic hysterectomy.

OBJECTIVE: To compare contained and free manual vaginal morcellation of large uteruses after total laparoscopic hysterectomy (TLH) in women at low risk of uterine malignancy in terms of feasibility and safety. METHODS: A single-center, observational, retrospective, cohort study was carried out including all patients undergoing TLH requiring manual vaginal morcellation for specimen extraction of large uteruses from January 2015 to August 2021 at the Division of Gynecology and Human Reproduction Physiopathology, IRCCS Azienda Ospedaliero-Universitaria of Bologna, Bologna, Italy. Patients were divided into two groups according to the type of manual vaginal morcellation (contained or free), and compared in terms of demographic, clinical, and perioperative data. RESULTS: In all, 271 patients were included: 186 (68.6%) in the contained morcellation group and 85 (31.4%) in the free morcellation group. The mean operative time was significantly lower in the contained morcellation group compared with the free morcellation group (median [interquartile range] 130 [45] vs. 155 [60] min; P < 0.001). No significant difference was found in complications related to the morcellation step, overall, intraoperative and postoperative complications, estimated blood loss, length of hospital stays, uterine weight, and rate of occult malignancy between the two groups. CONCLUSION: Contained vaginal manual morcellation of the uterus after total laparoscopic hysterectomy using a specimen retrieval bag appears to be a safe procedure with significantly lower operative time than free vaginal manual morcellation.

A rare case report of cervical hemangioma and a comprehensive literature review of 137 cases of cervical and uterine hemangiomas.

The cervix of the uterus is a rare site for cavernous hemangiomas. Cervical hemangiomas are slow-growing tumors with characteristic histological findings, including dilated vessels with increased endothelial cells. Although their pathophysiology remains unclear, hormones are believed to play an important role in the development of these vascular tumors. They may be asymptomatic due to their small size, but they can cause gynecological and obstetrical complications, including abnormal uterine bleeding and impaired fertility. Due to their small size, conservative treatment is the first line of management. Hysterectomy is considered for refractory cases or for patients who are not of childbearing age. In this study, firstly, we presented a case of a 60-year-old postmenopausal female without any gynecological-related signs or symptoms with a polypoid nodule hanging over the anterior cervical wall through its stalk. The surgical biopsy revealed no signs of neoplastic changes, with the only notable finding being a benign vascular lesion representing a cavernous hemangiomatous cervical polyp. The patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy and she is currently healthy without any further abnormal findings. Additionally, we provided a comprehensive review of 137 cases in the literature since 1883, detailing their characteristics, signs and symptoms, and pathology.

Diffuse uterine leiomyomatosis: a rare discovery.

PURPOSE: This case report aims to present a rare and challenging clinical scenario involving diffuse uterine leiomyomatosis (DUL), an infrequently encountered benign uterine pathology. The primary objective is to describe this unique case's clinical presentation, diagnostic challenges, and subsequent management. METHODS: A detailed analysis of the patient's medical history, diagnostic evaluations, and treatment approach was conducted. A relevant literature review on DUL was also performed. This case report includes high-resolution images and figures, showcasing MRI scans, surgical procedures, and histopathology slides related to the case. RESULTS: The case report outlines the clinical journey of a patient with DUL, an exceptionally rare uterine condition characterized by the uncontrolled proliferation of smooth muscle cells forming nodules and fascicles. This case illustrates the diagnostic complexities associated with DUL, as it mimics other uterine pathologies such as leiomyomas or adenomyosis. The patient's clinical presentation included abnormal uterine bleeding, heavy menstrual bleeding, fertility issues, and dysmenorrhea, leading to initial misdiagnoses. Surgical intervention eventually addressed the condition with corresponding images illustrating the procedures. CONCLUSION: This case report highlights DUL's rarity and diagnostic challenges. Clinicians must be vigilant when encountering similar clinical presentations, ensuring a comprehensive diagnostic workup to differentiate DUL from other uterine pathologies. Enhanced awareness among healthcare providers and further research into DUL's pathophysiology is essential for accurate diagnosis and timely management. The presented case underscores the need for tailored approaches to managing DUL and expanding the knowledge base surrounding this puzzling uterine disorder.

Uterine cervical stenosis: from classification to advances in management. Overcoming the obstacles to access the uterine cavity.

BACKGROUND: To date hysteroscopy is the gold standard technique for the evaluation and management of intrauterine pathologies. The cervical canal represents the access route to the uterine cavity. The presence of cervical stenosis often makes entry into the uterine cavity difficult and occasionally impossible. Cervical stenosis has a multifactorial etiology. It is the result of adhesion processes that can lead to the narrowing or total obliteration of the cervical canal. PURPOSE: In this review, we summarize the scientific evidence about cervical stenosis, aiming to identify the best strategy to overcome this challenging condition. METHODS: The literature review followed the scale for the quality assessment of narrative review articles (SANRA). All articles describing the hysteroscopic management of cervical stenosis were considered eligible. Only original papers that reported data on the topic were included. RESULTS: Various strategies have been proposed to address cervical stenosis, including surgical and non-surgical methods. Medical treatments such as the preprocedural use of cervical-ripening agents or osmotic dilators have been explored. Surgical options include the use of cervical dilators and hysteroscopic treatments. CONCLUSIONS: Cervical stenosis can present challenges in achieving successful intrauterine procedures. Operative hysteroscopy has been shown to have the highest success rate, particularly in cases of severe cervical stenosis, and is currently considered the gold standard for managing this condition. Despite the availability of miniaturized instruments that have made the management of cervical stenosis more feasible, it remains a complex task, even for experienced hysteroscopists.
