BACKGROUND Retroperitoneal leiomyomas(RLs)are rare benign tumours that can occur in the pelvic and/or abdominal parietal retroperitoneum.Once torsion occurs,it causes acute abdominal pain and can even lead to serious consequences such as gangrene,peritonitis,haemoperitoneum and shock if not identified and treated promptly.Therefore,a better understanding of the characteristics of RL torsion is needed.Here,we present a case of acute pedicle torsion of an RL in the posterior peritoneum followed by a literature review.CASE SUMMARY Herein,we report the case of a 42-year-old woman with RL torsion.The patient visited our hospital complaining of lower abdominal pain for 6 d.Pelvic examination revealed a tender mass superior to the uterus.Pelvic magnetic resonance imaging(MRI)revealed an anterior uterine mass,multiple uterine fibroids and slight pelvic effusion.MRI suggested the possibility of a subserosal myoma of the anterior uterine wall with degeneration.Intraoperative exploration revealed a 10 cm pedunculated mass arising from the posterior peritoneum,with the pedicle torsed two times.Pathological examination confirmed a torsed RL.CONCLUSION In the case of a pelvic mass complicated with acute abdomen,the possibility of torsion should be considered. 展开更多

They usually occur as a single lesion or as two or three nodules. Only two cases of esophageal multiple leiomyomas comprising more than 10 nodules have been reported previously. Moreover, there have been few reports of esophageal squamous cell carcinoma overlying submucosal tumors. We describe a 71-yearold man who was diagnosed as having a superficial esophageal cancer coexisting with two or three leiomyoma nodules. During surgery, 10 or more nodules that had not been evident preoperatively were palpable in the submucosal and muscular layers throughout the esophagus. As intramural metastasis of the esophageal cancer was suspected, we considered additional lymphadenectomy, but had to rule out this option because of the patient's severe anoxemia. Microscopic examination revealed that all the nodules were leiomyomas (20 lesions, up to 3 cm in diameter), and that invasion of the carcinoma cells was limited to the submucosal layer overlying a relatively large leiomyoma. This is the first report of superficial esophageal cancer coexisting with numerous solitary leiomyomas. Multiple minute leiomyomas are often misdiagnosed as intramural metastasis, and a leiomyoma at the base of a carcinoma lesion can also be rnisdiagnosed as tumor invasion. The present case shows that accurate diagnosis is required for the management of patients with coexisting superficial esophageal cancer and multiple leiomyomas. 展开更多

Background and aims: Adhesions can cause important morbidity including abdominal and pelvic pain, intestinal obstructions, and infertility. When adhesions are formed, there is no efficient method, nowadays, to resolve them, thus the reduction of their prevalence relies on the prevention. Profiling high risk patients for abdominal and pelvic adhesions (APA) is an important step to this prevention. The risk factors of adhesions in our institution, the association between APA, leiomyomas and skin scar anomaly (SSA) were investigated. Methods: A cross-sectional study was conducted from March 1st to June 30th 2013 including patients who underwent laparotomy or laparoscopy. Patients’ characteristics, presence of a SSA and leiomyomas, as related to adhesions, were analyzed. Student’s t, Pearson’s Khi-square, Fisher’s Exact, Mann-Whitney tests and logistic regression were used. P values < 0.05 were considered statistically significant. Results: The frequency of adhesions was 41.74%. Patients had a mean age of 32.69 ± 8.94 years. Those with a previous abdominal surgery (PAS), SSA and leiomyomas had respectively 12 times [OR: 11.98, CI95 (4.63 - 30.97)], 3 times [OR: 2.79, CI95 (1.16 - 6.71) and 2.5 times [(OR: 2.49, CI95 (1.07 - 5.78)] more adhesions. In logistic regression, a PAS and leiomyomas remained associated significantly to adhesions with p = 0.000 and p = 0.037 respectively. Conclusion: In peritoneal adhesions, leiomyomas and SSA are other factors that may allow a cautious selection of high risk patients who must benefit from particular attention during surgery. Further well designed studies are necessary to investigate the accurate clinical relation among those three conditions. 展开更多

AIM: To investigate the role of vascular endothelial growth factor (VEGF/and its receptors VEGFR-1 and 2 in the growth and differentiation of gastrointestinal strornal tumors (GISTs). METHODS: Thirty-three GISTs, 15 leiomyomas and 6 schwannomas were examined by immunohistochemistry in this study. RESULTS: VEGF protein was expressed in the cytoplasm of tumor cells, and VEGFRol and 2 were expressed both in the cytoplasm and on the membrane of all tumors. Irnrnunohistochernical staining revealed that 26 GISTs (78.8%), 9 leiornyornas (60.0%) and 3 schwannornas (50.0%/were positive for VEGF; 24 GISTs (72.7%/, 12 leiornyornas (80.0%) and 4 schwannornas (66.7%) were positive for VEGFR-1; 30 GISTs (90.9%/, 5 leiornyornas (33.3%/and 4 schwannornas (66.7%) were positive for VEGFR-2. VEGFR-2 expression was statistically different between GISTs and leiomyomas (P 〈 0.0001). However, there was no correlation between the expression of VEGF pathway componenets and the clinical risk categories. CONCLUSION: Our results suggest that the VEGF pathway may play an important role in the differentiation of GISTs, leiomyomas and schwannomas. 展开更多

Objective:To investigate the role of epidermal growth factor(EGF) in the pathogenesis of uterine leiomyomas.Methods:Human myometrial smooth muscle cells(HM-SMCs) and smooth muscle cells of human uterine leiomyomas(HL-SMCs) were separated from patients' specimens and cultured.After processed by EGF or PD98059(inhibitor of MKK/MEK) +EGF,the proliferation rate of both SMCs was detected by BrdU method and the phosphorylation level of p44/42 mitogen-activated protein kinase(MAPK) was determined by Western-blot.After different processing time by EGF,the phosphorylation levels of p44/42 MAPK and AKT and p27 expression level in both SMCs were detected by Western-blot.Results:EGF could significantly promote HL-SMCs proliferation and PD98059 could inhibit this effect(P<0.05);besides,PD98059 could inhibit the increase of the phosphorylation level of p44/42 MAPK in both SMCs induced by EGF.When the processing time by EGF was over 15 min,the phosphorylation levels of p44/42 MAPK and AKT in both SMCs decreased sharply and were close to zero:p27 expression in HM-SMCs raised significantly while the upregulation in HL-SMCs was little.Conclusions:EGF could not cause activation of EGFR because of the dephosphorylation of p44/42 MAPK and AKT in HL-SMCs,which caused p27 expression insufficiently and cell cycle dysregulation. 展开更多

BACKGROUND Gastric leiomyomas and gastric stromal tumors are the most common types of gastric tumors encountered.In recent years,the incidence of the two types of tumors has been increasing,but the differential diagnosis is still a challenge in clinical work.However,as there are many reports on stromal tumors and inflammation-related indicators are gradually being paid attention to as important factors in predicting tumor prognosis,the two main purposes of this study were to explore the inflammation-related differences between the two types of tumors and to develop a nomogram as a predictive model.AIM To explore the differences in platelet-lymphocyte ratio(PLR),neutrophillymphocyte ratio(NLR),lymphocyte mononuclear cell ratio(LMR),and SII between the two types of tumors,and simultaneously create the nomogram model.METHODS This study enrolled 88 patients in the gastric stromal tumor group and 56 patients in the gastric leiomyoma group,and the relevant data of the two groups were entered into the system for an integrated analysis.The primary objective of this study was to identify the differences in the inflammation index between the two types of tumors.RESULTS There were statistically significant differences between the two groups in sex,age,and tumor location.In comparison,gastric leiomyomas seem to be more common in women,young patients,and gastric cardia,which is in line with our previous research;the groups showed the following statistical differences:PLR(158.2%vs 134.3%,P=0.028),NLR(2.35 vs 1.68,P=0.000),LMR(5.75 vs 10.8,P=0.004),and SII(546.2 vs 384.3,P=0.003).The results of the multivariate logistic regression analysis showed that sex,age,tumor location,and LMR were independent risk factors for the identification of the two types of tumors.After considering the risk factors selected by the above analysis into the predictive model,a predictive model for distinguishing gastrointestinal stromal tumors from gastric leiomyomas was established as the nomogram.CONCLUSION Gastric leiomyomas and gastric stromal tumors are not only different in factors such as age of the patient,but also in inflammatory indicators such as LMR and PLR.We have established a predictive model related to the laboratory indicators and are looking forward to further research conducted in this clinical area. 展开更多

GISTs differ from other mesenchymal tumors of the gastrointestinal tract (e.g. leiornyomas and schwannomas). The purpose of this study was to investigate the role of Ets-1 in the growth and differentiation of GISTs. METHODS: Twenty-eight GISTs, nine leiomyomas and six schwannomas were examined by immunohistochemical staining method for Ets-1 in this study. Specimens were selected from surgical pathology archival tissues at Nagasaki University Hospital. RESULTS: Ets-1 protein was expressed in the cytoplasm of cells in all of these tumors. Immunohistochemical staining revealed that 27 GISTs (96.4%), six leiomyomas (66.7%), and five schwannomas (83.3%) were positive for Ets-1. Ets-1 expression was statistically different between GISTs and leiomyomas (P〈0.005). However, there was no correlation between Ets-1 expression and clinical risk categories. CONCLUSION: Ets-1 plays an important role in the growth and differentiation of GISTs, leiomyomas and schwannomas. 展开更多

In searching of differentially expressed genes in human uterine leiomyomas, differential display was used with twelve pairs of primers to compare human uterine leiomyomas with matched myometrium. False positives were eliminated by reverse Northern analysis. Positives were confirmed by Northern blot analysis. RESULTS: Four of 69 cDNA fragments (3 up-regulated named L1, L2 and L3 and 1 down-regulated named M1 in leiomyoma) were confirmed by Northern analysis. Sequence comparison and Northern analysis proved that L1 is exactly the human ribosomal protein S19. It was present ubiquitously in 13 tissues tested but in various levels and even in different size. L1 was highly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPS19 overexpression might be a universal signal in rapid cell growth tissues. 展开更多

Objective: To investigate the clinicopathology and DNA ploidy of gastric mucosa associated lymphoid tissue (MALT) lymphoma infiltraving the leiomyomas of the uterus of a patient. Methods: The routine paraffin slides were cut, stained with HE, immunochemically by ABC methodusing the and stained by Feulgen method. Then the DNA ploidy of tumor cells was measured with an image cytometer. Results: In the mucosa, submucosa and the smooth muscle layer of the stomach and in the leiomyomas of the uterus there was diffusive and dense infiltration of centrocyte-like cells. The DNA measurement results were that the distribution of DNA mass of lymphoma cells in stomach and in lymph nodes had a single main aneuploidy peak each, and the distribution of DNA mass of lymphoma cells in leiomyomas of uterus had two peaks; one of them was the diploid, the other aneuploid. Conclusion: The MALT lymphoma cell invasion in uterus must be differentiated with a primary lymphoma in the uterus, the chronic lymphocyte leukemia in uterus and an endometrial stromal sarcoma. The present prognosis of the patient under discussion was poor. The follow-up results indicated the DNA index seemed to be important for predicting the malignancy degree and prognosis. 展开更多

Background Ultrasound (US) is a popular method in the diagnosis and treatment of uterine leiomyomas, but the lack of accuracy greatly limits its application. Recently, microbubble enhancement technique affords direct depiction of tumor neovascularity and establishes a more precise vascular map of the tumor. This study was undertaken to describe the distribution patterns of SonoVue, a second-generation contrast agent, in the micrecirculation of uterine leiomyomas, and to investigate the potential use of contrast-enhanced ultrasound (CEUS) in the characterization and treatment of uterine leiomyomas.Methods Ninety-six patients with uterine leiomyomas were enrolled in this study. The CEUS was performed using cadence pulse sequencing technique (CPS) and SonoVue. Enhancement patterns of different lesions were observed.The diagnostic accuracy of CEUS was compared with that of conventional ultrasound.Results After contrast injection, vessels of macro- and micro-circulation of the myoma first appeared, followed by the normal myometrium and finally the endometrium. During the washout phase, the myoma exhibited homogeneous enhancement followed by apparent hypoenhancement. The margin of the tumor was depicted clearly. There was no agent perfusion in the benign degenerative or necrotic area. However in sarcomas degeneration, the feeding vessels appeared markedly earlier than those in myometrium. In addition, the tumor exhibited heterogeneous hyperenhancment with no agent perfusion in the center and no membraniform sign was observed in the late phase. In subserous andsubmucous leiomyomas, the feeding arteries in the pedicle arising from the uterine could be seen. In this study, the diagnostic accuracy of CEUS and conventional US for uterine leiomyomas was 96.7% (160/165) and 82.4% (136/165)respectively.Conclusions CEUS can provide a precise description of the leiomyomas vascularization. The specific enhancement pattern may be helpful for the characterization, treatment choice and therapeutic monitoring of leiomyomas. 展开更多

BACKGROUND Leiomyomas(LMs)are mesenchymal tumors that arise from smooth muscle cells.LMs most commonly arise in organs with an abundance of smooth muscle such as the uterus and gastrointestinal tract.Conversely,LMs are rarely detected in the head and neck region.In this study,we report a rare case of laryngeal LM(LLM)and summarized the clinical characteristics of reported LLMs to help clinicians better understand this rare disease and improve its diagnosis,treatment,and postoperative course.CASE SUMMARY A 49-year-old man was admitted to our ENT outpatient clinic with a chief complaint of pharynx discomfort for 2 months.Laryngoscopy performed under topical anesthesia revealed a solitary,pink mass at the tubercle of epiglottis.Surgery via laryngeal endoscopy was performed under general anesthesia,and the lesion was excised easily.Positive immunohistochemical staining for desmin and smooth-muscle actin indicated a smooth muscle origin and the diagnosis was laryngeal leiomyoma.After surgery,the patient’s condition was stable,and he was discharged 2 d after surgery.During the 1-year postoperative period,the patient’s condition remained stable without evidence of recurrence.CONCLUSION Surgical resection is the preferred treatment for LLMs,its early diagnosis and differential diagnosis have important clinical significance. 展开更多

BACKGROUND Endoscopic resection of giant gastric leiomyomas,particularly in the fundus and cardia regions,is infrequently documented and presents a significant challenge for endoscopic surgery.CASE SUMMARY Herein,a case of a 59-year-old woman with a giant gastric leiomyoma was reported.The patient presented to the department of hepatological surgery with a complaint of right upper abdominal pain for one month and worsening for one week.The patient was diagnosed as gastric submucosal tumor(SMT),gallstone,and cholecystitis combined with computed tomography and gastroendoscopy prior to operation.Upon admission,following a multi-disciplinary treatment discussion,it was determined that the patient would undergo a laparoscopic cholecystectomy and endoscopic resection of gastric SMT.It took 3 hours to completely resect the lesion by Endoscopic submucosal excavation and endoscopic fullthickness resection,and about 3 hours to suture the wound and take out the lesion.The lesion,ginger-shaped and measuring 8 cm×5 cm,led to transient peritonitis post-surgery.With no cardiac complications,the patient was discharged one week after surgery.CONCLUSION Endoscopic resection of a giant leiomyoma in the cardiac fundus is feasible and suitable for skilled endoscopists. 展开更多

BACKGROUND Gastric mesenchymal tumors(GMT)are identified as soft tissue neoplasms that arise from mesenchymal stem cells within the gastrointestinal tract.GMT pri-marily encompass gastric stromal tumors(GST),gastric leiomyomas,and gastric schwannomas.Although most GMT are benign,there are still potential malignant changes,especially GST.Thus,early surgical intervention is the primary treat-ment for GMT.We have designed a simple endoscopic“calabash”ligation and resection(ECLR)procedure to treat GMT.Its efficacy and safety need to be com-pared with those of traditional endoscopic techniques,such as endoscopic sub-mucosal excavation(ESE).AIM To assess the safety and effectiveness of ECLR in managing small GMT(sGMT)with a maximum diameter≤20 mm by comparing to ESE.METHODS This retrospective analysis involved patients who were hospitalized in our institution between November 2021 and March 2023,underwent endoscopic resection,and received a pathological diagnosis of GMT.Cases with a tumor diameter≤20 mm were chosen and categorized into two cohorts:Study and control groups.The study group was composed of patients treated with ECLR,whereas the control group was composed of those treated with ESE.Data on general clinical characteristics(gender,age,tumor diameter,tumor growth direction,tumor pathological type,and risk grade),surgery-related information(complete tumor resection rate,operation duration,hospitalization duration,hospitalization cost,and surgical complications),and postoperative follow-up were collected for both groups.The aforementioned data were subsequently analyzed and compared.RESULTS Five hundred and eighty-nine individuals were included,with 297 cases in the control group and 292 in the study group.After propensity score matching,the final analysis incorporated 260 subjects in each cohort.The findings indicated that the study group exhibited shorter operation duration and lowered medical expenses relative to the control group.Furthermore,the study group reported less postoperative abdominal pain and had a lower incidence of intraoperative perforation and postoperative electrocoagulation syndrome than the control group.There were no substantial variations observed in other parameters among the two cohorts.CONCLUSION ECLR is a viable and effective approach for managing sGMT. 展开更多

AIM: To study the endoscopic, pathological and immunoo histochemical features of esophageal mesenchymal tumors. METHODS: Twenty-nine patients diagnosed as esophageal rnysenchymal tumors by electronic endoscopy and endoscopic ultrasound (EUS) were observed under light microscopes, and all tissues were stained by the immunohistochemical method. The expression of CD117, CD34, SMA and desmin were measured by staining intensity of cells and positive cell ratios. RESULTS: Endoscopically, esophageal gastrointestinal stromal tumors (GISTs) and leiomyomas (LMs) had similar appearances, showing submucosal protuberant lesions. They all showed low echo images originated from the muscularis propria or muscularis mucosa on EUS. Endoscopy and EUS could not exactly differentiate esophageal GISTs from LMs. Microscopically, there were two kinds of cells: spindle cell type and epitheloid cell type in esophageal GISTs. Leiomyomas and leiomyosarcornas were only of spindle cell type. One malignancy was found in five cases of esophageal GISTs, and one malignancy in 24 cases of leiomyomas and leiomyosarcomas. Using Fisher's exact method, the differences of malignant lesion proportion were not significant between esophageal LMs and GISTs, 1/5 vs 1/24 (P 〉 0.05). All cases of esophageal GISTs were positive for CD117, and 3 cases were also positive for CD34. The 24 cases of leiomyomas and leiomyosarcomas were all negative for CD117 and CD34. The differences of positive rates of CD117 and CD34 were significant between esophageal GISTs and LMs, 5/5 vs 0/24, 3/5 vs 0/24 (P 〈 0.005). All leiomyomas and leiomyosarcomas were positive for SMA, and desmin. Among 5 cases of esophageal GISTs, 2 cases were SMA positive, and 1 case was desmin positive. The differences in positive rates and expression intensity of SMA and desmin were significant between esophageal LMs and GISTs, 24/24 vs 2/5, 24/24 vs 115 (P 〈 0.005). CONCLUSION: The most common esophageal mesenchymal tumors are leiomyomas, and esophageal GISTs are less common. Most of esophageal LMs and GISTs are benign. Endoscopy and EUS are the effective methods to diagnose esophageal mesenchymal tumors and they can provide useful information for the treatment of these tumors. However, they cannot exactly differentiate esophageal GISTs from LMs. Pathological, especially immunohistochemical features are useful to differentiate GISTs from leiomyomas. 展开更多

AIM: To investigate the role of angiopoietin (Ang) -1, -2 and -4 and its receptors, Tie-1 and -2, in the growth and differentiation of gastrointestinal stromal tumors (GISTs).METHODS: Thirty GISTs, seventeen leiomyomas and six schwannomas were examined by immunohistochemistry in this study.RESULTS: Ang-1, -2 and -4 proteins were expressed in the cytoplasm of tumor cells, and Tie-1 and -2 were expressed both in the cytoplasm and on the membrane of all tumors. Immunohistochemical staining revealed that 66.7% of GISTs (20 of 30), 76.5% of leiomyomas (13 of 17) and 83.3% of schwannomas (5 of 6) were positive for Ang-1. 83.3% of GISTs (25 of 30), 82.4% of leiomyomas (14 of 17) and 100% of schwannomas (6 of 6) were positive for Ang-2. 36.7% of GISTs (11 of 30), 58.8% of leiomyomas (10 of 17) and 83.3% of schwannomas (5 of 6) were positive for Ang-4. 60.0% of GISTs (18 of 30), 82.4% of leiomyomas and 100% of schwannomas (6 of 6) were positive for Tie-1. 10.0% of GISTs (3 of 30), 94.1% of leiomyomas (16 of 17) and 33.3% of schwannomas (2 of 6) were positive for Tie-2. Tie-2 expression was statistically different between GISTs and leiomyomas (P < 0.001). However, there was no correlation between expression of angiopoietin pathway components and clinical risk categories.CONCLUSION: Our results suggest that the angiopoietin pathway plays an important role in the differentiation of GISTs, leiomyomas and schwannomas. 展开更多
