Objective:To study the clinical and pathological features, immunophenotypes, molecular genetics characteristics, differential diagnosis, and prognostic factors of pulmonary and tracheal glomus tumors.Method:Eight cases of pulmonary and tracheal glomus tumors were collected in Jiangsu Provincial Hospital (including 1 consultation, from Gaochun People's Hospital, Nanjing, China) between May 2015 and April 2023, and their clinical and imaging data, pathological morphology, and immunohistochemical characteristics were retrospectively analyzed. Gene testing and follow-up were performed.Result:There were 5 males and 3 females with onset ages ranging from 29 to 75 years old, median age 63.5 years. Among the patients, 5 cases were located in the trachea and 3 cases in the lungs. Under light microscopy, 5 cases were benign glomus tumors with clear boundaries, diffuse sheet or nest-like distribution, small, round or short spindle-shaped tumor cells, rounded and centered nuclei, and no obvious nuclear mitosis was seen. Two cases of glomus tumor of uncertain malignant potential showed an infiltrative growth pattern involving smooth muscle, nerves and blood vessels with necrosis and calcification, the tumor cells were more uniform in size, round or short spindle-shaped nuclei, and no obvious nuclear mitosis was seen; One case of malignant glomus tumor was seen in sarcomatous areas, lung membrane invasion and necrosis, the tumor cells were highly heterogeneous, binucleated and multinucleated, with nuclear mitoses of 20/50 high power field (HPF), and pathologic nuclear mitoses were easy to be seen. Immunohistochemically, SMA, Calponin, H-caldesmon, Vimentin and Collagen Ⅳ were all positive (8/8). Some cases expressed Syn (3/8) and Bcl-2 (4/8). The Ki-67 proliferation index was 1-2% (7/8) and 40% (1/8). BRAF V600E were detected as wild-type (8/8), and no mutations were detected in exons 2, 3, and 4 of KRAS human EML4- ALK fusion gene were negative in 5 surgical cases. Case 6 showed HMBOX1- ALK gene fusion, TERT gene mutation and CDKN2A gene deletion, and case 8 showed CARMN- NOTCH2 gene fusion. Seven cases were followed up (8-103 months, median follow-up time 30 months), 1 case was lost, 1 case recurred 21 months after surgery, and others with no evidence of recurrence or metastasis. Conclusions:Pulmonary and tracheal glomus tumors are very rare and need to be differentiated from other common tumors by combining pathological morphology and immunohistochemistry. Maybe there are some differences in the malignant diagnostic criteria and molecular genetic characteristics between visceral derived glomus tumors and soft tissue derived tumors of the same kind, such as limbs and skin. More data accumulation is needed.

Objective:To investigate the intervention effect of exercise rehabilitation based on constructivism teaching mode on pelvic girdle pain (PGP) in pregnant women in late pregnancy, and to provide guidance for improving the pregnancy experience of PGP pregnant women.Methods:A quasi-experimental study was conduced, from November 2023 to February 2024, using convenience sampling method to select late pregnant women with PGP who had been filed and had regular obstetric checkups in the Second Hospital of Shandong University as the study subjects, they were randomly divided into intervention group (granted exercise rehabilitation based on the constructivism teaching model) and control group (granted exercise rehabilitation based on the traditional teaching model) according to the random number table method. Compare the pain scores and teaching effectiveness of pregnant women before and after the intervention in the two groups.Results:The final number of the two groups were 50 in each group, aged (32.38 ± 3.93) years in the intervention group; aged (31.34 ± 3.19) years in the control group. After the intervention, the pain scores of pregnant women in the intervention group (1.48 ± 1.26) scores were significantly lower than those in the control group (2.96 ± 1.42) scores, and the difference was statistically significant ( t = -5.45, P<0.05). The scores of the evaluation of the teaching effect memory problem scores, movement mastery scores, and classroom evaluations were (7.96 ± 1.30) scores, (13. 96 ± 0.88) scores, (27.54 ± 3.08) scores in the intervention group, which were significantly higher than those in the control group (5.80 ± 1.29) scores, (8.48 ± 1.82) scores, (16.24 ± 3.80) scores, the differences were statistically significant ( t = 8.30, 19.16, 16.31, all P<0.05). Conclusions:Based on the constructivism teaching model, exercise rehabilitation for pregnant women with PGP in late pregnancy can effectively alleviate their pelvic girdle pain, and the teaching effect is better than the traditional teaching model, which has the potential to be promoted and applied in the teaching of obstetric maternity schools.

Objective:To analyze the histopathological features of primary aldosteronism(PA) based on the histopathology of primary aldosteronism(HISTALDO) consensus classification in patients undergoing unilateral adrenalectomy and explore its correlation with clinical characteristics and postoperative outcomes.Methods:A retrospective study was conducted on 105 unilateral PA patients treated at the First Affiliated Hospital of Nanjing Medical University between April 2017 and April 2022. Postoperative histopathology was classified according to the latest HISTALDO consensus and compared with traditional classifications. Differences in clinical features and primary aldosteronism surgical outcomes(PASO) were analyzed across classifications.Results:HISTALDO classification showed that 67.6% of patients were classical subtype and 32.4% were non-classical subtype. Compared to the non-classical group, the classical group showed lower age, body mass index, serum potassium concentration, fasting blood glucose, HbA 1C, and proportion of CYP11B2 negative nodules as well as higher systolic blood pressure, diastolic blood pressure, prevalence of hypokalemia, and 24-hour urine potassium(all P<0.05). Based on PASO criteria, complete clinical and biochemical success were achieved in 41.7% and 83.3% subjects respectively. A significantly higher proportion of classical group displayed complete clinical and biochemical success than nonclassical group(all P<0.05). Multivariate logistic regression analysis showed that lower serum potassium concentration( OR=0.15, 95% CI 0.03-0.84, P<0.05) and proportion of CYP11B2 negative nodules( OR=0.20, 95% CI 0.05-0.86, P<0.05) were related to classical pathological type, and classical pathological type was independently related to clinical and biochemical remission(all P<0.05). Conclusion:Standardized HISTALDO histopathological classification enhances diagnostic accuracy and predicts postoperative outcomes in unilateral PA, providing a foundation for precise stratified management of PA patients.

Co-occurrence of renal cell carcinoma with two different histology is very rare. Here we present a 61-year-old gentleman with right renal mass in clinics. The diagnosis was right renal cell carcinoma by two different enhanced mass showing on CT scan. Right laparoscopic nephrectomy was performed. Pathology showed that one mass was papillary renal cell carcinoma, the other was clear cell renal cell carcinoma. No recurrence or metastasis was found during 36 months of follow up.

Objective:To investigate the clinicopathological characteristics, genetic features, diagnosis and differential diagnosis of pulmonary artery intimal sarcoma (PAIS).Methods:Three cases of PAIS were collected from Jiangsu Province People′s Hospital (from February 2016 to November 2019). The clinical data, imaging examination, morphology, immunostaining, and molecular changes were retrospectively analyzed.Results:There were 1 male and 2 females (age: 32, 50, 60 years), who had symptoms of cough, asthma or chest tightness. Imaging findings indicated low density filling defects which were suspected as thrombus, embolism or myxoma. Grossly, the main tumor was located in the elastic arteries and their lobar branches, also extended into the atrium and ventricle, with lung parenchymal infiltration focally. Microscopically, tumor cells were predominantly composed of abundant spindle cells with obvious atypia and myxoid background, resembling fibroblastic or myofibroblastic differentiation. Active mitotic figures and necrosis could be seen in some areas. Immunohistochemical staining of vimentin was strongly positive, while pan-cytokeratin, S-100, desmin, Fli-1, CD31, SMA and ERG etc were variably positive only in focal areas. FISH detection showed amplification of MDM2 gene in three cases and EGFR gene in two cases. Metastatic lesions were found in one case by 18, 32 and 42 months after surgery respectively. There was no recurrence or metastasis in the other two cases.Conclusions:PAIS is one of exceptionally poor differentiated mesenchymal tumor that arises from the arterial intima of elastic pulmonary arteries. There was no definite differention in morphology. Gene detection shows amplification of MDM2 and EGFR gene. This tumor often has poor prognosis with aggressive behavior. Complete resection is the only effective therapeutic option. There is disagreement as to whether chemotherapy and radiotherapy can improve survival.
