ObjectiveTo investigate the clinicopathological features, diagnosis and differential diagnosis of villoglandular carcinoma of the uterine cervix. MethodsThe clinical data of a 34-year-old patient diagnosed with villoglandular carcinoma of cervix on April 6, 2010 was retrospectively analyzed. Surgical excision samples were analyzed by means of hematoxylin-eosin and immunohistochemical staining. ResultsThe gross appearance of the tumor mass showed cauliflower-like pattern of growth. Histologically, it was similar to colorectal villoglandular adenoma, and was composed of branching papillae shaped like villous glandular tube structure, and the surface was coated with pseudostratified or stratified columnar cells which showed mild atypia and uncommon mitotic figures. Immunohistochemically, tumor cells were positive for carcinoma embryonic antigen, CK7 and CA125, and negative for estrogen receptor, progesterone receptor, P16, p53 and vimentin. This patient was subjected to a follow-up of 48 months, and was alive without recurrence or metastasis. ConclusionsVilloglandular carcinoma of the uterine cervix is rare and has a favorable prognosis. The diagnosis of villoglandular carcinoma depends on pathological morphology, and meanwhile, it is necessary to distinguish villoglandular carcinoma from other benign and malignant tumors which exhibited papillary growth pattern.
ObjectiveTo investigate the value of ultrasound contrast in the differential diagnosis for hepatocellular carcinoma (HCC) and hepatic focal nodular hyperplasia (FNH). MethodsTwenty-three HCC patients and 23 cases hepatic FNH patients from January 1, 2012 to January 1, 2014 in our hospital were selected, all of them were underwent ultrasound contrast examination before operation. The ultrasound contrast results of 2 groups patients were comparative analyzed. ResultsIn HCC group, the contrast arrival time was (3.8±1.9) s, peak time was (21.8±11.9) s, and peak strength was (28.8 ±3.1) dB; in hepatic FNH group, these indicators was (2.3±1.4) s, (35.3±14.8) s, and (22.3±7.9) dB, respectively. These indicators of HCC group was longer or shorter or higher than those of hepatic FNH group, respectively (P < 0.05). The sensitivity, specificity, and accuracy of ultrasound contrast diagnosed HCC was 91.3% (21/23), 87.0% (20/23), and 95.7% (22/23), and diagnosed hepatic FHN was 87.0% (20/23), 91.3% (21/23), and 91.3% (21/23), respectively, the difference were not statistically significant between the two groups (P > 0.05). ConclusionUltrasound contrast has very important application value in the differential diagnosis of HCC and hepatic FNH, can be used in clinical application.
Objective To assess the significance of multi-detector row CT in differential diagnosis of the inguinal hernia and femoral hernia. Methods CT images which were reconstructed by multi-planer reconstruction （MPR） of 260 patients with inguinal hernia and femoral hernia who treated in our hospital form Oct. 1， 2012 to Oct. 31， 2013 were analyzed retrospectively， for exploring the relationship between sac and anatomic structure in the groin area. Results There were 146 patients with indirect hernia （75 in right， 60 in left， and 11 in bilateralism）， 82 patients with direct hernia（39 in right， 34 in left， and 9 in bilateralism）， and 32 patients with femoral hernia （17 in right and 15 in left）. The 157sacs of patients with indirect hernia originated lateral to the inferior epigastric artery， entered the inguinal canal and through the deep ring， which mainly located anterior （103/157， 65.6%） or anteromedial （36/157， 22.9%） to the spermatic cord or round ligament. The 91 sacs of patients with direct hernia originated medial to the inferior epigastric artery， and mainly located medial to the spermatic cord （70/91， 76.9%）. Sacs of both indirect hernia and direct hernia located anterosuperior to the inguinal ligament. The 32 sacs of patients with femoral hernia located posterior to the inguinal ligament and inside the “radiological femoral triangle” of coronal views. Conclusions The MPR images available from multi-detector row CT permit the accurate diagnosis of groin hernias. By using simple anatomical criteria， direct hernia， indirect hernia， and femoral hernia can be reliably distinguished．
Objective To investigate clinical significance of serum VEGF-C level and C-erbB-2 protein expression in patients with breast cancer. Methods Sixty-two female patients with breast invasive ductal cancer and breast benign lesion were respectively selected. Serum VEGF-C level was detected by enzyme-linked immunosorbent assay (ELISA) before operation and at one month after operation, and C-erbB-2 protein expression in tissues of breast cancer was detected by immunohistochemistry. Then, the relationship between serum VEGF-C level and clinicopathologic characteristics and C-erbB-2 protein expressions wereas analyzed. Results The serum VEGF-C level before operation in breast cancer patients〔(279.65±17.34) pg/ml〕 was significantly higher than that in breast benign lesions patients 〔(167.26±12.15) pg/ml〕, P＜0.01. In breast cancer patients, the serum VEGF-C level before operation was higher than that at one month after operation 〔(209.45±15.23) pg/ml〕, P＜0.01. The serum VEGF level was related to tumor stage (P＜0.05) but not to patient age, tumor size, menopause status , lymph node metastasis or not and ER and PR expression (Pgt;0.05). The positive expression rate of C-erbB-2 protein in breast cancer patients (54.84%, 34/62) was significantly higher than that in breast benign lesion patients (11.29%, 7/62), P＜0.01. Moreover, the positive expression rate of C-erbB-2 protein in breast cancer patients with axilla lymph node metastasis (69.44%) was significantly higher than that without axilla lymph node metastases (34.62%), P＜0.05. The serum VEGF level increased with increasing expression intensity of C-erbB-2 protein and there was positive correlation between them (r=0.813，P＜0.05). Conclusions The serum VEGF-C level in breast cancer may be conducted as an assisted marker to differential diagnosis of breast tumor. C-erbB-2 is related to lymph node metastasis of breast cancer patients. There is synergistic effect between VEGF-C and C-erbB-2 in the lymph node metastasis way of breast cancer.
ObjectiveTo investigate the value of contrastenhanced ultrasonography in differential diagnosis between benign and malignant breast mass. MethodsTotally 65 patients with 70 breast masses were evaluated by general ultrasonography and contrastenhanced ultrasonography with contrast agent SonoVue. The related indexes, such as the degree and mode of contrast enhancement, the lesion boundaries and dissipation mode, were used to describe the difference between benign and malignant mass, which was also compared with pathological results. ResultsHistopathological examination revealed that benign mass was in 37 cases and malignant in 28 cases. The sensitivity, accuracy, positive predictive value, and negative predictive value of contrastenhanced ultrasonography with contrast agent SonoVue were significantly higher than that of general ultrasonography (Plt;0.05), while no significant difference in diagnostic specificity and misdiagnosis rate was observed between them (Pgt;0.05). All tumors showed contrast enhancement in various degrees. Of 28 patients with enhanced mass, hyperenhancement in 22 cases and nodular inhomogeneous enhancement in 21 cases were observed and the boundaries of malignant tumor were irregular with ill-defined and radial enhancement. Most of benign tumors were represented by weak, homogeneous enhancement, and the shape was regular with smooth and tidy boundary and intact capsule except seven cases with unclear boundary. These imaging characteristics of benign and malignant tumors were obviously different (P=0.000). In the resolution phase, both benign and malignant mass showed heterogeneous or homogeneous dissipation, which was not significantly different (P=0.791). ConclusionCompared with general ultrasonography, contrast enhanced ultrasonography may be more helpful for the differential diagnosis of benign and malignant breast tumors.
Abstract： Sarcoidosis is a common systemic disease with noncaseating granulomatous epithelioid nodule and coexisting granulomatous inflammation. Although sarcoidosis can affect any organ of the body， more than 90% of the patients demonstrate thoracic involvement， which is often confusing with lung cancer and other diseases. Therefore, thoracic surgeons must have a clear understanding of sarcoidosis. Moreover， due to the special role of surgery in obtaining pathological specimens， thoracic surgeon plays an important role in the diagnosis and treatment of sarcoidosis. It is not difficult to make diagnosis for patients with typical clinical features of sarcoidosis. However， the majority of patients do not have specific manifestations of sarcoidosis. The cause of sarcoidosis remains unknown， and there is also no specific treatment strategy for it. But recent research has shown that annexin A11 gene may be involved in the pathogenesis of sarcoidosis， and tumor necrosis factor （TNF） inhibitor is effective in the treatwent of sarcoidosis.
ObjectiveTo evaluate the differential diagnosis and treatment of nonfunctional parathyroid cyst. MethodsThe data of 6 patients with nonfunctional parathyroid cyst, who underwent operation in general surgical department of China Medical University Shengjing Hospital between January 2003 and April 2013 were retrospectively analized. ResultsNo patient got definite diagnosis before operation.Preoperative diagnosis were thyroid cyst in 4 patients, neck mass in 1 patient, and thyroid cancer in 1 patient.All patients received operation, included parathyroid cystectomy in 5 patients and thyroid cancer radical resection plus parathyroid cystectomy in 1 patient.Two patients were lost to follow-up, 4 patients were followed-up for 9-24 months, average 19 months, there were no parathyroid cyst and thyroid cancer recurrence or metastasis. ConclusionsNonfunctional parathyroid cyst is true cyst, it is rare lesion in neck, and preoperative definite diagnosis rate is low.The cystectomy is a safe and effective treatment method.
Objective To evaluate the diagnostic value of analyzing the pattern of gallbladder wall enhancement on MDCT to identify the different causes of acute cholecystitis. Methods In January 2009 to December 2012， 169 patients diagnosed with acute cholecystitis caused by various pathologic conditions were performed MDCT scans， the images of portal venous phase and clinical data were retrospectively reviewed by two blinded radiologists. There were 146 cases in non-hepatopathy cholecystitis group and 23 cases in hepatopathy cholecystitis group. The other 5 normal gallbladder cases diagnosed by MDCT scans were retrospectively reviewed as contrast group. Using five patterns according to the enhancement pattern of flat gallbladder wall thickening on MDCT. The study cases were then divided into five patterns and the thickness of the mucous membrane were measured. The occurrence rate of each pattern and the thickness of the mucous membrane between the groups were compared respectively. Results In the non-hepatopathy cholecystitis group， there were typeⅡin 102 cases （69.9%）， typeⅢin 5 cases （3.4%）， typeⅣ in 30 cases （20.5%）， and typeⅤ in 9 cases （6.2%）. In the hepatopathy cholecystitis group， there were typeⅡin 2 cases （8.7%）， typeⅢ in 11 cases （47.9%）， typeⅣin 5 cases （21.7%）， and typeⅤin 5 cases （21.7%）. The occurrence rate of typeⅡin the non-hepatopathy cholecystitis group was significialtly higher than that in the hepatopathy cholecystitis group （P＜0.005）. The occurrence rate of typeⅢ and typeⅤ in the hepatopathy cholecystitis group were significialtly higher than those in the non-hepatopathy cholecystitis group（P＜0.005， P＜0.05）. The occurrence rate of type Ⅳ between the two groups had no significant difference （P＞0.05）. TypeⅠonly present in the contrast group. The non-hepatopathy group’s mean mucous membrane thickness was （2.61±1.30） mm ， which was thicker than the hepatopathy group’s （2.02±0.52） mm（t=2.22， P＜0.05）. Conclusion Analyzing the enhancement pattern of a thickened gallbladder wall on MDCT is helpful in identifying the causes of acute cholecystitis， and the gallbladder perforation or not.
ObjectiveTo systematically review the clinical value of the contrast-enhanced ultrasonic in the diagnosis of breast tumors. MethodsWe electronically and comprehensively searched the databases including The Cochrane Library (Issue 2, 2013), PubMed, CNKI, WanFang Data, Chaoxing medalink, VIP, and CBM for clinical research reports of diagnosing breast cancer with Contrast-enhance ultrasonic (all from foundation to May 2013). Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies according to the QUADAS items. The Meta-DiSc software (version 1.4) was used to conduct pooling on sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Heterogeneity test was performed and the summary receiver operating characteristic (SROC) curve was drawn for area under the curve (AUC). ResultsA total of 19 studies involving 1 161 participants were included. The results of meta-analysis showed that, specificity, the pooled sensitivity, positive likelihood ratio, negative likelihood ratio and DOR were 0.79 (95%CI 0.75 to 0.82), 0.86 (95%CI 0.83 to 0.89), 3.92 (95%CI 2.77 to 6.56), 0.18 (95%CI 0.13 to 0.26), and 25.86 (95%CI 13.77 to 48.55), respectively. The AUC of the SROC curve was 0.917 0. ConclusionThe current evidence shows that contrast-enhanced ultrasonic has high sensitivity and specificity in the diagnosis of preoperative benign and malignant breast mass, which indicates that it could be used as a good method to diagnosing breast tumors.
Diagnosis and treatment of solitary pulmonary nodule (SPN, less than 30 mm in diameter) has been a formidable problem in clinical work. It is often detected in medical examination or other disease examinations by chance. There are no corresponding signs and symptoms of SPN except those on the imaging, so it is difficult to make a correct diagnosis as early as possible. Literature shows that there is a certain probability of malignant SPN, so early correct diagnosis is the key factor in deciding the prognosis and appropriate treatment. With the accumulation of clinical experiences, the development of new fiberoptic bronchoscopy, highresolution CT, and videoassisted thoracoscopic surgery, as well as the evolution of some invasive examination technologies, it is less difficult in distinguishing benign from malignant SPN than ever before. In this article, we will make a comprehensive review on the development in the aspect of differential diagnosis of SPN.
