RESUMEN
Most mesenchymal tumors found in the uterine corpus are benign tumors; however, uterine leiomyosarcoma is a malignant tumor with unknown risk factors that repeatedly recurs and metastasizes. In some cases, the histopathologic findings of uterine leiomyoma and uterine leiomyosarcoma are similar and surgical pathological diagnosis using excised tissue samples is difficult. It is necessary to analyze the risk factors for human uterine leiomyosarcoma and establish diagnostic biomarkers and treatments. Female mice deficient in the proteasome subunit low molecular mass peptide 2 (LMP2)/ß1i develop uterine leiomyosarcoma spontaneously. MATERIAL AND METHODS: Out of 334 patients with suspected uterine mesenchymal tumors, patients diagnosed with smooth muscle tumors of the uterus were selected from the pathological file. To investigate the expression status of biomarker candidate factors, immunohistochemical staining was performed with antibodies of biomarker candidate factors on thin-cut slides of human uterine leiomyosarcoma, uterine leiomyoma, and other uterine mesenchymal tumors. RESULTS AND DISCUSSION: In human uterine leiomyosarcoma, there was a loss of LMP2/ß1i expression and enhanced cyclin E1 and Ki-67/MIB1 expression. In human uterine leiomyomas and normal uterine smooth muscle layers, enhanced LMP2/ß1i expression and the disappearance of the expression of E1 and Ki-67/MIB1 were noted. The pattern of expression of each factor in other uterine mesenchymal tumors was different from that of uterine leiomyosarcoma. CONCLUSIONS: LMP2/ß1i, cyclin E1, and Ki-67/MIB1 may be candidate factors for biomarkers of human uterine leiomyosarcoma. Further large-cohort clinical trials should be conducted to establish treatments and diagnostics for uterine mesenchymal tumors.

OBJECTIVE: To develop a novel scoring system based on magnetic resonance imaging (MRI) for predicting the difficulty of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation for uterine fibroids. MATERIALS AND METHODS: A total of 637 patients with uterine fibroids were enrolled. Sonication time, non-perfused volume ratio (NPVR), and ultrasound energy delivered for ablating 1 mm3 of fibroid tissue volume (E/V) were each classified as three levels and assigned scores from 0 to 2, respectively. Treatment difficulty level was then assessed by adding up the scores of sonication time, NPVR and E/V for each patient. The patients with score lower than 3 were categorized into low difficulty group, with score equal to or greater than 3 were categorized into high difficulty group. The potential predictors for treatment difficulty were compared between the two groups. Multifactorial logistic regression analysis model was created by analyzing the variables. The difficulty score system was developed using the beta coefficients of the logistic model. RESULTS: Signal intensity on T2WI, fibroid location index, largest diameter of fibroids, abdominal wall thickness, homogeneity of the signal of fibroids, and uterine position were independent influencing factors for the difficulty of USgHIFU for uterine fibroids. A prediction equation was obtained: difficulty score = 17 × uterine position (anteverted =0, retroverted =1)+71 × signal intensity (hypointense = 0, isointense/hyperintense = 1) +8 × enhancement (homogenous = 0, heterogeneous = 1)+25×(largest diameter of fibroids-20) +35 × (fibroid location index -0.2) +1×(abdominal wall thickness -5). CONCLUSIONS: This scoring system established based on MRI findings can be used to reliably predict the difficulty level of USgHIFU treatment of uterine fibroids.

Pulmonary benign metastasizing leiomyoma is an uncommon condition, predominantly affecting women of childbearing age with a history of uterine smooth muscle tumors and uterine leiomyoma surgery for uterine leiomyoma. The progression of PBML is often unpredictable and depends on the extent of lung involvement. Generally, most patients remain asymptomatic, but a minority may experience coughing, wheezing, or shortness of breath, which are frequently misdiagnosed as pneumonia. consequently, this presents significant challenges in both treatment and nursing care before diagnosis. This paper reports the case of a 35-year-old woman primarily diagnosed with acute hypoxic respiratory failure who was transferred from the emergency room to the intensive care unit. The initial computed tomography scan of the patient's lungs indicated diffuse interstitial pneumonia, but the sequencing of the alveolar lavage fluid pathogen macro did not detect any bacteria, fungi, or viruses. Moreover, the patient remained in a persistent hypoxic state before the definitive diagnosis. Therefore, our focus was on maintaining the airway patency of the patient, using prone ventilation, inhaling nitric oxide, monitoring electrical impedance tomography, and preventing ventilator-associated pneumonia to improve oxygenation, while awaiting immunohistochemical staining of the patient's biopsied lung tissue. This would help us clarify the diagnosis and treat it based on etiology. After meticulous treatment and nursing care, the patient was weaned off the ventilator after 26 days and transferred to the respiratory ward after 40 days. This case study may serve as a reference for clinical practice and assist patients suffering from PBML.

BACKGROUND/AIMS: Gastrointestinal stromal tumors are common gastric mesenchymal tumors that are potentially malignant. However, endoscopic ultrasonography is poor in diagnosing gastrointestinal stromal tumors. The study investigated the efficacy of texture features extracted from endoscopic ultrasonography images to differentiate gastrointestinal stromal tumors from gastric mesenchymal tumors. MATERIALS AND METHODS: The endoscopic ultrasonography examinations of 120 patients with confirmed gastric gastrointestinal stromal tumors, leiomyoma, or schwannoma were evaluated. Histology was considered the gold standard. Three feature combinations were extracted from endoscopic ultrasonography images of each lesion: 48 gray-level co-occurrence matrix-based features, 48 gray-level co-occurrence matrix-based features plus 3 global gray features, and 15 gray-gradient co-occurrence matrix-based features. Support vector machine classifiers were constructed by using feature combinations to diagnose gastric gastrointestinal stromal tumors. The area under the receiver operating characteristic curve, accuracy, sensitivity, and specificity were used to evaluate the diagnostic performance. The support vector machine model's diagnostic performance was compared with the endoscopists. RESULTS: The 3 feature combinations had better performance in differentiating gastrointestinal stromal tumors: gray-gradient cooccurrence matrix-based features yielded an area under the receiver operating characteristic curve of 0.90, which was significantly greater than an area under the receiver operating characteristic curve of 0.83 in gray-level co-occurrence matrix-based features and an area under the receiver operating characteristic curve of 0.84 in the texture features plus 3 global features. The support vector machine model (81.67% accuracy, 81.36% sensitivity, and 81.97% specificity) was also better than endoscopists (an average of 69.31% accuracy, 65.54% sensitivity, and 72.95% specificity) Conclusion: Texture features in computer-assisted endoscopic ultrasonography diagnosis are useful to differentiate gastrointestinal stromal tumors from benign gastric mesenchymal tumors and compare favorably with endoscopists. Support vector machine model using gray-gradient co-occurrence matrix-based texture features revealed the best diagnostic performance in diagnosing gastric gastrointestinal stromal tumors.

Herein, we aimed to examine the diagnostic yield and utility of boring biopsy for subepithelial lesions (SEL) of the stomach and esophagus. A total of 52 patients with SELs of the stomach or esophagus underwent boring biopsy. The diagnostic yield of boring biopsy for gastric and esophageal SELs was 50% (21/42) and 80% (8/10), and for SELs with a diameter of less than 10mm, the diagnostic yield was 67% (6/9) and 83% (5/6), respectively. Forty-three percent (9/21) of the gastric SELs were diagnosed with gastrointestinal stromal tumor (GIST), while all esophageal SELs (8/8) were leiomyomas. Ten percent (4/42) of boring biopsies for the stomach were accompanied by complications:two cases of perforation and two of bleeding.

Evaluating gynecological mass lesions and reviewing their morphological characteristics based on their imaging appearance on magnetic resonance imaging (MRI), and correlating the MRI findings with histopathological findings, was the central theme of our study. This observational cross-sectional study was conducted on 60 female patients with clinically suspected gynecological mass lesions upon physical examination and/or ultrasonography, referred for MRI at a tertiary care hospital over a 1-year period between June 2022 and July 2023. A broad spectrum of differential diagnoses of gynecological masses was observed. In our study, the ratio of benign versus malignant disease was 1.6:1, with 37 benign and 23 malignant masses identified. The most common benign masses were uterine fibroids (nâ =â 14; 23.3%), followed by endometriosis (nâ =â 8; 13.3%), and ovarian dermoid cysts (nâ =â 4; 6.6%). Among the malignant lesions, cervical cancer was the most common (nâ =â 11; 18.3%), followed by endometrial carcinoma (nâ =â 7; 11.6%), ovarian carcinoma (nâ =â 3; 5%), and vaginal carcinoma (nâ =â 2; 3%). Benign lesions mostly appeared hypo- to isointense on T1-weighted imaging and iso- to hyperintense on T2-weighted imaging, while malignant lesions appeared isointense on T1-weighted and hyperintense on T2-weighted imaging. Hemorrhage and fat were well appreciated on MRI and aided in diagnosis. T2 shading was present in 7 out of 8 endometriotic cysts, demonstrating a specificity of 100% and a sensitivity of 83%. For determining parametrial invasion in cervical carcinoma, MRI showed an accuracy of 91%, specificity of 100%, and positive predictive value, negative predictive value, and sensitivity of 100%, 75%, and 88%, respectively. In cases of endometrial carcinoma, MRI demonstrated a sensitivity and specificity of 87% and 91%, respectively, with a positive predictive value of 87% and a negative predictive value of 91% for identifying myometrial invasion greater than 50%. Compared to other modalities, MRI provided substantial information regarding uterine and adnexal masses and surrounding structures, facilitating accurate staging of lesions.

OBJECTIVE: To assess the efficacy of mechanical resection through TruClear™ hysteroscopy in patients with endometrial polyps and submucosal fibroids. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Obstetrics and Gynaecology, Shifa International Hospital, Islamabad, Pakistan, from June 2018 to 2022. METHODOLOGY: Patients diagnosed with endometrial polyps and submucosal fibroids confirmed by abdominal or transvaginal ultrasonography were included. Patients having a history of congestive cardiac failure, chronic kidney disease, and bleeding diathesis were excluded from the study. Data about the complete removal of pathology (endometrial polyps and submucosal fibroids), mean operating time, and postoperative complications such as bleeding and perforation were extracted. The follow-up was set up to 6 months after the procedure. RESULTS: The average age of the 45 patients was 35.62 ± 7.46 years. Heavy menstrual bleeding was the most prevalent symptom, seen in 73.3% of cases, followed by irregular vaginal bleeding (IVB) in 11.1% of cases. The most frequent disease identified by sonography was a polyp in 21 (47%) instances, followed by submucosal fibroids in 12 (27%) cases, mixed pathology in 10 (22%), and malignancy in 2 (4%) cases. The overall average operative time was 36.46 ± 24.94 minutes. A hundred percent removal of lesions was observed in this study. Persistent symptoms were observed in 13% of patients after the surgery so they were treated with other interventions. The most common intervention was an intrauterine hormonal device. Intraoperative bleeding was observed in only one patient and was managed by intraoperative intrauterine balloon insertion. The recurrence rate was 8.9% (4/45). CONCLUSION: TruClear™ hysteroscopy showed a major advantage in the successful and complete removal of the pathology, low operation time, and complications. KEY WORDS: Fibroids, Hysteroscopy, Polyps, Endometrial resection, Menstrual bleeding.

Leiomyoma is a benign tumour of smooth muscle origin. Leiomyoma arising in major salivary gland is under-reported. We report a case of a woman in her 40s with a submandibular gland tumour which represented a diagnostic challenge during preoperative assessment. The core needle biopsy of submandibular gland tumour revealed a spindle cell tumour suggestive of an undifferentiated tumour. As a malignancy could not be excluded, the submandibular gland tumour was removed en bloc with surrounding lymph nodes in level Ib of the neck. Leiomyoma may be included in the differential diagnosis of spindle cell salivary gland tumours, particularly when there are no signs of infiltration and preoperative investigations are inconclusive.

Lipoleiomyomas are rare variants of uterine leiomyomas rarely studied in the literature. We retrospectively studied 20 cases of uterine lipoleiomyomas showing that these lesions represent 0.7â¯% of all uterine leiomyomas diagnosed histologically. The patients did not experience any recurrence, and the tumors showed no morphological criteria of malignancy. They did not show significant p16, p53 or MiB1 expression. They showed diffuse and strong expression or estrogen and progesterone receptors by the smooth muscle component but without accompanying expression by the adipocytic component in one third of the cases. Androgen receptors were rarely expressed. They expressed in their majority HMGA2 in both components, while RB1 was usually not found. Fumarate hydratase (FH) is expressed by lipoleiomyomas, while they are negative for HMB45. In conclusion, uterine lipoleiomyomas are rare, benign tumors, characterized by HMGA2 expression, while they show no elements suspicious of malignancy, PEComas or FH deficiency. The role of RB1 in these tumors should be further explored.

Understanding the molecular factors involved in the development of uterine myomas may result in the use of pharmacological drugs instead of aggressive surgical treatment. ANG1, CaSR, and FAK were examined in myoma and peripheral tissue samples taken from women after myoma surgery and in normal uterine muscle tissue samples taken from the control group. Tests were performed using tissue microarray immunohistochemistry. No statistically significant differences in ANG1 expression between the tissue of the myoma, the periphery, and the normal uterine muscle tissue of the control group were recorded. The CaSR value was reduced in the myoma and peripheral tissue and normal in the group of women without myomas. FAK expression was also lower in the myoma and periphery compared to the healthy uterine myometrium. Calcium supplementation could have an effect on stopping the growth of myomas.

RATIONALE: Primary ovarian leiomyoma is a rare benign tumor. The exact histological origin and pathogenesis of primary ovarian leiomyoma are still unclear, while its preoperative imaging diagnosis is often challenging and prone to misdiagnosis. The study aims to elucidate the diagnosis of primary ovarian leiomyoma and to distinguish it from fibroma. PATIENT CONCERNS: A 34-year-old female was admitted to the hospital with complaints of pelvic mass found for one year. One years ago, the patient went to a local hospital for examination due to irregular menstruation. DIAGNOSES: The ultrasound report of the patient showed ovarian teratoma. The postoperative pathological results showed ovarian leiomyoma and calcification. INTERVENTIONS: The patient underwent laparoscopic right ovarian leiomyoma resection. OUTCOMES: The patient was discharged home three days after surgery. At the most recent follow-up (five months after operation) of the patients, ultrasound was performed and no abnormal echoes were suggested in the adnexal region. LESSONS: In the diagnosis of primary ovarian leiomyoma, our case emphasizes the importance of microscopic features as an effective approach to distinguish it from ovarian fibroma, leiomyosarcoma, and stromal tumors. Additionally, personalized treatment should be considered based on the patient age and fertility needs.

Current medical therapies for fibroids have major limitations due to their hypoestrogenic side effects. Based on our previous work showing the activation of NF-kB in fibroids, we hypothesized that inhibiting NF-kB in vivo would result in the shrinkage of tumors and reduced inflammation. Fibroid xenografts were implanted in SCID mice and treated daily with Bay 11-7082 (Bay) or vehicle for two months. Bay treatment led to a 50% reduction in tumor weight. RNAseq revealed decreased expression of genes related to cell proliferation, inflammation, extracellular matrix (ECM) composition, and growth factor expression. Validation through qRT-PCR, Western blotting, ELISA, and immunohistochemistry (IHC) confirmed these findings. Bay treatment reduced mRNA expression of cell cycle regulators (CCND1, E2F1, and CKS2), inflammatory markers (SPARC, TDO2, MYD88, TLR3, TLR6, IL6, TNFα, TNFRSF11A, and IL1ß), ECM remodelers (COL3A1, FN1, LOX, and TGFß3), growth factors (PRL, PDGFA, and VEGFC), progesterone receptor, and miR-29c and miR-200c. Collagen levels were reduced in Bay-treated xenografts. Western blotting and IHC showed decreased protein abundance in certain ECM components and inflammatory markers, but not cleaved caspase three. Ki67, CCND1, and E2F1 expression decreased with Bay treatment. This preclinical study suggests NF-kB inhibition as an effective fibroid treatment, suppressing genes involved in proliferation, inflammation, and ECM remodeling.

Disseminated peritoneal leiomyomatosis (DPL) is a rare and benign clinical entity. It is also known as leiomyomatosis peritonealis disseminata (LPD). Here, we report and discuss a case of a primiparous woman in her early 40s who presented with heavy, prolonged, painful menses and heaviness in her lower abdomen. She underwent a laparoscopic myomectomy for a fibroid uterus, 12 months ago for similar complaints. On workup, she was diagnosed with DPL. We performed a total abdominal hysterectomy with bilateral salpingectomy, low anterior resection with stapled colorectal anastomosis and excision of peritoneal tumour deposits in consortium with the gastrosurgery team. Her postoperative period was uneventful, and the patient was discharged on postop day 6. Her histopathology report was consistent with leiomyoma; the follow-up period was uneventful.

Uterine pathologies pose a challenge to women's health on a global scale. Despite extensive research, the causes and origin of some of these common disorders are not well defined yet. This study presents a comprehensive analysis of transcriptome data from diverse datasets encompassing relevant uterine pathologies such as endometriosis, endometrial cancer and uterine leiomyomas. Leveraging the Comparative Analysis of Shapley values (CASh) technique, we demonstrate its efficacy in improving the outcomes of the classical differential expression analysis on transcriptomic data derived from microarray experiments. CASh integrates the microarray game algorithm with Bootstrap resampling, offering a robust statistical framework to mitigate the impact of potential outliers in the expression data. Our findings unveil novel insights into the molecular signatures underlying these gynecological disorders, highlighting CASh as a valuable tool for enhancing the precision of transcriptomics analyses in complex biological contexts. This research contributes to a deeper understanding of gene expression patterns and potential biomarkers associated with these pathologies, offering implications for future diagnostic and therapeutic strategies.

OBJECTIVE: To evaluate the impact of high-intensity focused ultrasound (HIFU) ablation on the histopathological features of locally recurrent fibroids tissue. METHODS: Patients who underwent transabdominal hysterectomy or myomectomy for uterine fibroids from January 1, 2021 to July 1, 2023 at a teaching hospital in China were enrolled in this prospective study. The patients who underwent surgery for local recurrence of uterine fibroids after HIFU ablation were categorized as the HIFU group, and patients who had not undergone HIFU ablation for uterine fibroids were the control group. Hematoxylin-eosin (HE) staining, Masson staining, and immunohistochemical staining were performed to analyze the counts of smooth muscle cells (SMCs), collagen content, microvascular count, and the expression levels of estrogen receptor (ER) and progesterone receptor (PR) in the fibroid tissue specimens. RESULTS: The mean SMC counts in the HIFU and control groups were 337.68/field and 328.52/field respectively. The mean collagen content in the HIFU group and control group were 46.06% and 41.69% respectively. The mean microvessel counts in the HIFU group and control group were 13.66/field and 14.08/field respectively. The mean ER scores in the HIFU and control groups were 6.9 and 7.47 respectively, and the mean PR scores were 7.3 and 7.56 respectively. Overall, there were no significant differences in the SMC counts, collagen content, microvascular counts, and the ER and PR expression levels between the HIFU group and control group (p > 0.05). CONCLUSIONS: HIFU ablation has no effect on the pathological characteristics of local recurrent fibroid tissue, and is an ideal non-invasive treatment option.

OBJECTIVE: Uterine fibroids increase the risk of preterm birth. The current study highlights uterine fibroid necrosis as a possible cause of (extreme) preterm birth. STUDY DESIGN: Retrospective cohort study in one Dutch academic hospital. Cases were selected from the 526 participants of the MyoFert study (Netherlands Trial Register, NL7990), which included patients who presented between 2004 and 2018 and were between the age of 18 and 45 years at the time of diagnosis of uterine fibroids. Of these participants, 414 women became pregnant. A retrospective chart review of the first pregnancies was performed. The main outcomes were (imminent) preterm birth and signs of fibroid necrosis on ultrasound. In women with signs of fibroid necrosis, the following data were collected systematically: fibroid characteristics, clinical presentation, pregnancy outcome, and postpartum period. RESULTS: In total, 66 women had a preterm birth (16 %, 66/414), of which 25 pregnancies ended between 16 and <24 weeks (38 %, 25/66) and 41 pregnancies ended between 24 and <37 weeks of gestation (62 %, 41/66). Of all women with preterm birth and available ultrasound images, 15 % (7/48) had fibroid necrosis at the time of labour. These seven patients, supplemented with three patients with fibroid necrosis during their first pregnancy and at least one episode of imminent preterm birth, are described in more detail. In these ten patients, the fibroids increased substantially in size during the first and second trimester, leading to severe abdominal pain in all patients and hospital admission in seven patients. Ultrasound examination of the fibroids showed heterogenic changes and focal transonic areas in the fibroid, which are characteristics that indicate fibroid necrosis. In four patients, myomectomy was performed and necrosis was confirmed histologically. CONCLUSION: Fibroid necrosis during pregnancy is likely associated with (imminent) preterm birth. Clinicians are advised to structurally evaluate the myometrium in pregnancy, specifically in women presenting with abdominal pain in the second trimester.

OBJECTIVE: To evaluate fertility outcomes based on size and number of intramural leiomyomas and outcomes after removal. DATA SOURCES: Online searches: MEDLINE, ClinicalTrials.gov , PubMed, Cochrane Library, and PROSPERO Library from 1994 to 2023. METHODS OF STUDY SELECTION: A total of 5,143 studies were identified, with inclusion of 13 study groups. TABULATION, INTEGRATION AND RESULTS: Outcomes for size and number of leiomyomas were reported with clinical pregnancy rates and ongoing pregnancy or live-birth rates. In data sets with maximum leiomyoma diameters of less than 6 cm for study inclusion, women with leiomyomas smaller than 3 cm had lower clinical pregnancy rates than women without leiomyomas, with an odds ratio (OR) of 0.53 (95% CI, 0.38-0.76) and, for ongoing pregnancy or live-birth rates, an OR of 0.59 (95% CI, 0.41-0.86). The ORs for clinical pregnancy rates in women with intermediately-sized leiomyomas (those between 3 cm and 6 cm) were lower than in women without leiomyomas, with an OR at 0.43 (95% CI, 0.29-0.63) and, for ongoing pregnancy or live-birth rates, an OR at 0.38 (95% CI, 0.24-0.59). In data sets without exclusion for women with larger-sized leiomyomas, clinical pregnancy rates were lower for those with leiomyomas smaller than 5 cm compared with those without leiomyomas, with an OR of 0.75 (95% CI, 0.58-0.96). Women with leiomyomas larger than 5 cm showed no differences in clinical pregnancy rate compared with women without leiomyomas, with an OR of 0.71 (95% CI, 0.32-1.58). Although women with a single leiomyoma in any location had no differences in outcomes, those with more than one leiomyoma had lower clinical pregnancy rates and ongoing pregnancy or live-birth rates, with an OR of 0.62 (95% CI, 0.44-0.86) and 0.57 (95% CI, 0.36-0.88), respectively. The clinical pregnancy rate for women undergoing myomectomy for intramural leiomyomas was no different than those with intramural leiomyomas in situ, with an OR of 1.10 (95% CI, 0.77-1.59). CONCLUSION: Even small intramural leiomyomas are associated with lower fertility; removal does not confer benefit. Women with more than one leiomyoma in any location have reduced fertility.

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

AIM: To demonstrate a rare case of ciliary body leiomyoma in our patient Case report: A 72-year-old female reported to our clinic for a preventive examination, upon which we found a dome-shaped grey-brownish mass on the retinal periphery. After completing gonioscopic and ultrasound examinations, we referred the patient to a specialist facility. Due to a finding of suspicious malignant melanoma, we completed the MRI scan and recommended enucleation of the eyeball. A histopathological examination showed a leiomyoma of the ciliary body. CONCLUSION: The aim of this case report is to demonstrate the difficulty of intraocular leiomyoma diagnosis. Only immunohistochemical examination differentiated the tumor from malignant melanoma and determined the diagnosis of ciliary body leiomyoma. Perhaps because of the extreme rarity of this type of tumor, we often neglect to consider a diagnosis of leiomyoma.
