We report a case of a 68yearold man with gastric AM admitted to our hospital for melana. Endoscopic examination revealed a gastric mass of about 4 cm in diameter, located in the antrum. Histologic examination of the excised specimen showed irregularly arranged glands and interlacing smooth muscle bundles surrounding the glandular elements. Although gastric AM is rare, it should be considered in differential diagnosis of extramucosal gastric tumor.展开更多

A 28-year-old man presented with anorexia, nausea and pain in the right upper abdomen. On physical examination, the abdomen was tender to palpation and Murphy sign was positive. The patient underwent a cholecystecomy. This case, in our opinion, is very interesting since it permits to consider a controversial issue in the pathology of the gallbladder. The histological appearance of ductal structure in pancreatic heterotopia resembles the histological picture of both Aschoff-Rokitansky （AR） sinuses and adenomyomas. This finding suggests that these lesions are linked by a common histogenetic origin. We suggest that the finding of an adenomyoma in the gallbladder should prompt an extensive sampling of the organ in order to verify the coexistence of pancreatic rests.展开更多

The case is a 51-year-old man who was hospitalized for yellow color skin and sclera and itching for 2 mo without abdominal pain. Nothing special was found in physical examination except yellowish skin and sclera. The clinical presentation and Computerized Tomography (CT),Magnetic resonance cholangiopancreatography (MRCP),and ultrasonography suspected a tumor of the distal bile duct. The patient was treated successfully by pancreaticoduodenectomy. Histologically,the lesion consisted of adenoid and myofibrous tissue and moderate atypia. The immunophenotype of the epithelial component was cytokeratin 7+/cytokeratin 20-. The patient has been well without any evidence of recurrence for 12 mo since his operation.展开更多

Despite its benign nature,ampullary adenomyoma is usually presented as biliary obstruction. Most cases are misdiagnosed as carcinoma or adenoma by preoperative endoscopic or radiologic procedure. Therefore,it is frequently treated with extensive surgery. To our knowledge,this is the first reported case in English literature of adenomyoma located in the peripancreatic orifice resulting in intermittent pancreatic duct obstruction and recurrent pancreatitis diagnosed by the endoscopic piecemeal resection.展开更多

Pat...Atypical polypoid adenomyoma (APAM) is a rare polypoid tumor that generally occurs in women of reproductive age who have abnormal genital bleeding. The tumor was reported as a new disease concept by Mazur in 1981. Pathologically, APAM consist of irregularly proliferated endometrial gland cells and interlacing bundles of smooth muscle cells within the stroma, and have a similar form to adenocarcinoma, adenofibroma, adenosarcoma, and carcinosarcoma. Therefore, differential diagnosis is required in many cases. APAM is pathologically classified as a benign lesion and clinically has a comparatively favorable outcome. However, treatment and follow-up observation should be performed carefully because recurrence and residual lesions occur in many patients after conservative treatment. Concomitant development of endometrial adenocarcinoma also occurs in many cases and it is difficult to differentiate this disease from APAM. Thus, diagnosis of APAM should be made carefully, particularly since the number of cases of endometrial adenocarcinoma has increased in recent years. Furthermore, APAM tends to develop during a woman’s reproductive years, and fertility sparing treatment should be considered. Here, we review the clinicopathological characteristics of APAM, including the difficulty of diagnosis as a benign or malignant uterine tumor, and we examine the relationship between APAM and endometrial cancer.展开更多

It is would distinguished from well-differentiated endometrial adenocarcinoma because of his histological features. We report 2 cases of 31-year-old and 33-year-old patient whose symptom were abnormal uterine bleeding. The mass was pedunculated with a narrow pedicle connecting to the pedunculated with a narrow pedicle connecting to the cervical;the other was in the uterine prolapse without pedicle. The surgical procedure was polypectomy only in all two patients with hysteroscopy. The histopathology showed the lesions were composed of a proliferation of irregular atypical endometrial glands separated by varying amounts of cellular smooth-muscle stroma. No mitotic activity was observed in the epithelial or mesenchymal elements in APA. The treatment of APA should depend on the age and reproductive desire of patient.展开更多

Unfortunetly, we still have no effective way to treat this kind of diseases. This study was aimed to evaluate the efficacy and surgical characteristics of modified adenomyomectomy. Methods This is a retrospective study and the subjects were collected in the past 5 years. We divided the subjects by the two different surgical procedures. Cases of adenomyoma patients who underwent conservative surgery, modified adenomyomectomy or wedge resection of the adenomyoma lesion were distributed to two groups retrospectively. Surgical characteristics, symptom relief, and recurrence were analysed in each group. Results General characteristics, including operation time, blood loss, and postoperative complication were similar in both groups. In the modified adenomyometomy group, the median follow-up time was 27.6 months and the rate of relief of dysmenorrhea and menorrhagia symptoms were 91.2% and 40.0%, respectively. In the wedge resection group, the rate of reliefe of dysmenorrhea and menorrhagia symptoms were 88.9% and 50.0%, respectively. Patients in both groups had statistically significant symptom relief, but there was no statistical difference between them. During the following time, ultrasonography relapse rate in modified modified adenomyomectomy group is significantly lower than the wedge resection group 15.0% vs. 69.2% （P 〈0.001）. The relapse rate, in terms of symptoms, was 5.0% in the modified adenomyomectomy group, which was similar to the relapse rate in the wedge resection group. In terms of reproductive outcome, 33.3% of the patients with infertility complications in the modified adenomyomectomy group became pregnant. Among them, the rate of pregnancy by assisted reproductive techniques was 45.5%, which was significantly higher than the rate of natural pregnancy, 23.1% （P =0.039）. Conclusion Modified adenomyomectomy appears to be a safe and effective operative method that shows advantages in reducing the rate of relapse after surgery.展开更多

文摘Gastric adenomyoma (AM) is a rare benign tumor characterized by glandlike structures embedded within a smooth muscle stroma. We report a case of a 68yearold man with gastric AM admitted to our hospital for melana. Endoscopic examination revealed a gastric mass of about 4 cm in diameter, located in the antrum. Histologic examination of the excised specimen showed irregularly arranged glands and interlacing smooth muscle bundles surrounding the glandular elements. Although gastric AM is rare, it should be considered in differential diagnosis of extramucosal gastric tumor.

文摘To investigate the evaluation value of intravoxel incoherent motion diffusion-weighted imaging(IVIM-DWI)on the early efficacy of magnetic resonance-guided high-intensity focused ultrasound(MRgFUS)ablation for uterine adenomyoma.The clinical and magnetic resonance imaging(MRI)data of 36 patients with uterine adenomyoma before and after MRgFUS treatment in our hospital from January 2018 to December 2018 were retrospectively analyzed.All the 36 patients underwent MRI examination one day before operation and immediately after operation using GE Discovery MR7503.0T MRI,including conventional sequences(T1WI,T2WI,and T2 fat suppression sequences)plain scan,IVIM-DWI sequences with 9 b values,and contrast enhanced-MRI sequences.The IVIM-DWI quantitative parameters(true diffusion coefficient D,perfusion related diffusion coefficient D*,and perfusion fraction f)of double-exponential model were obtained by using GE ADW 4.7 functool,a postprocessor.SPSS 24.0 software was used to analyze the difference in parameter between the ablation and non-ablation areas of uterine adenomyoma.DWI signal in the ablation area of uterine adenomyoma was increased,and manifested as heterogeneous diffuse high signal,with low central signal and high edge signal.Values of D,D*and f in the ablation area of uterine adenomyoma were significantly lower than those in the non-ablation area,and there was statistical difference between the two(P<0.05).The areas under receiver operating characteristic(ROC)curve of D,D*and f values in the ablation area of uterine adenomyoma were 0.854,0.898 and 0.924,respectively;the optimal thresholds for the diagnosis of ablation area of uterine adenomyoma were 0.81×10−3 mm2/s,4.99×10−3 mm2/s and 0.24,respectively;the diagnostic sensitivity was 80.6%,72.2%and 94.4%,respectively;and the specificity was 91.7%,97.2%and 94.4%,respectively.IVIM-DWI has a certain clinical value in the evaluation on early efficacy of MRgFUS ablation of uterine adenomyosis.
