Objective:To explore the clinical manifestations of IgG4-related diseases（IgG4-RD） complicated with moderately differentiated adenosquamous carcinoma of the parotid gland, the diagnostic criteria for IgG4-related diseases and parotid malignant tumors, treatment regimens, and the application of fine-needle aspiration in disease diagnosis, so as to reduce clinical misdiagnosis and missed diagnosis. Methods:A retrospective analysis was conducted on the case data of a patient with IgG4-related diseases（IgG4-RD） complicated with moderately differentiated adenosquamous carcinoma of the parotid gland admitted to our department in March 2024. The clinical characteristics, imaging findings, preoperative puncture results, and postoperative pathological features were analyzed, and relevant literatures on both diseases were reviewed and summarized. Results:The elderly male patient was admitted due to "a mass in the parotid area in front of the right ear for more than 3 months". Through clinical examination, imaging examination, laboratory examination, and preoperative needle biopsy, the diagnosis of "right parotid moderately differentiated adenosquamous carcinoma complicated with IgG4-related disease" was considered. It was also considered that IgG4-related disease did not involve other organs before surgery, so no systemic hormone therapy was given before or after surgery. After surgery combined with postoperative radiotherapy, follow-up showed that neither the parotid tumor nor IgG4-related disease recurred. Conclusion:"IgG4-related disease complicated with moderately differentiated adenosquamous carcinoma"is a rare clinical disease. Both lack typical clinical manifestations and specific imaging features, and the diagnosis is mostly unclear before surgery. Pathological examination is of great significance in the diagnosis of the disease, while fine-needle aspiration has limited value in the diagnosis, which should attract the attention of clinicians. In addition, for patients with both diseases, individualized treatment plans should be formulated.

A 30-year-old female patient with a benign tumor in the superficial lobe of the left parotid gland underwent tumor resection via a 5 cm intra-hairline incision, using the da Vinci Xi surgical robot combined with the NIM-Response 3.0 facial nerve monitoring system. During the operation, facial nerve branches were located and protected through facial nerve monitoring, and the robotic arms were used for precise tumor dissection. Postoperatively, the facial nerve function, incision healing, and tumor recurrence were observed. duration of the procedure was 120 minutes, and the tumor（2.0 cm×1.5 cm） was completely resected. Postoperative pathological examination indicated a pleomorphic adenoma. During the 3-month postoperative follow-up, the patient's facial nerve function remained normal, no salivary fistula occurred, the incision was hidden within the hairline, no tumor recurrence was found in the ultrasound reexamination, and the patient was highly satisfied with the appearance. The surgical approach of robot-assisted resection of benign parotid gland tumor via a hairline incision under facial nerve monitoring has significant advantages in facial nerve protection and cosmetic effect, and is suitable for patients with benign parotid gland tumors meeting specific conditions.

A 57-year-old woman with a 2-year history of a left infra-auricular mass with no associated symptoms presented with a 6.0 cm ´ 4.0 cm ´ 3.0 cm firm, non-tender, movable mass. No imaging was done. Fine needle aspiration biopsy (FNAB) revealed sheets of epithelial cells that had abundant dense grayish-blue cytoplasm in a mucinous background with abundant lymphocytes (Figure 1), suggestive of salivary gland neoplasm with oncocytic or oncocytoid features (Category IVB, Salivary Gland Neoplasm of Uncertain Malignant Potential).Total parotidectomy revealed a 4.3 X 3.2 X 3.0 cm deep lobe lesion with a tan-grey to dark brown, smooth and dull external surface. Cut sections showed a cream-white to pink, lobulated, heterogenous cut surfaces. Microscopically, the lesion was unencapsulated with poorly demarcated borders. The neoplastic cells were arranged in haphazard sheets and surrounded by abundant lymphocytes. The tumor cells had abundant eosinophilic and granular cytoplasm compatible with oncocytes with mild to moderate nuclear atypia. There were occasional cystic spaces that contained mucin though mucocytes were not readily apparent. (Figure 2) Necrosis, perineural and lymphovascular space invasion or anaplasia were not evident.

OBJECTIVE: To analyze the epidemiological characteristics of measles, mumps, and rubella (MMR) between 2014 and 2021 and identify potential strategies and measures for the prevention and control of MMR in China. METHODS: Data on MMR was obtained from China's National Notifiable Disease Reporting System for the period from 2014 to 2021. Spatiotemporal distributions were analyzed using SaTScan; temporal trends were analyzed using JoinPoint; and clusters were visualized using ArcGIS. RESULTS: A total of 1,808,067 cases of MMR were reported from 2014 to 2021 in China's mainland, most of which were children and students under the age of 20. The incidence of measles declined during 2014-2021, whereas that of mumps and rubella peaked in 2019. MMR-reported cases generally peaked from March to July; however, high numbers of mumps cases were reported from September to November in 2020-2021. Measles and rubella clusters predominantly occurred in Western China, whereas clusters of mumps were generally found in the southern region. CONCLUSION The relatively heterogeneous epidemiological characteristics of MMR have highlighted the weaknesses and gaps in surveillance and timely control of MMR transmission in China's mainland. Real-time and intelligent monitoring data should be collected for evidence-based early interventions.

Objective: To investigate the expression of TRPS1 in salivary gland-type breast carcinoma and its clinical application. Methods: A total of 30 cases of salivary gland-type breast carcinoma diagnosed from May 2015 to November 2022 at the Department of Pathology of the First Affiliated Hospital of Nanjing Medical University were collected. The expression of TRPS1 was detected by immunohistochemistry and compared with that of GATA3. TRPS1 and GATA3 expression in 24 cases of primary salivary gland carcinoma. Results: There were 10 cases of breast secretory carcinoma, aged 21-61 years (median 53.5 years), with the size ranging from 0.9-2.2 cm (median 1.6 cm), 2 of which were accompanied by axillary nodal macrometastasis. All patients were alive after 2-55 months of follow-up (median 29.5 months, mean 29.7 months). There were 20 cases of breast adenoid cystic carcinoma, aged 36-77 years (median 53.5 years), with the size ranging from 1.2-5.5 cm (median 2.5 cm), 3 of which were accompanied by axillary nodal macrometastasis. All patients were alive after 3-92 months of follow-up (median 22.5 months, mean 31.7 months), and 1 patient had lung metastasis 15 months after surgery. The medium/high expression ratio of TRPS1 in breast secretory carcinoma was 10/10, which was higher than that of GATA3 (7/10). TRPS1 was also positive in the 2 cases with lymph node metastases. The medium/high expression rate of TRPS1 in breast adenoid cystic carcinoma was 20/20, which was significantly higher than that of GATA3 (2/20). TRPS1 was highly expressed in both classic and solid subtypes, while GATA3 was only expressed in a few cases of the classic subtype. TRPS1 was also positive in 3 cases with lymph node metastases and 1 case of the pulmonary metastases. The expression level of TRPS1 was the same in 1 case before and after neoadjuvant chemotherapy. In addition, TRPS1 was positive in parotid secretory carcinoma and adenoid cystic carcinoma. The medium/high expression rate of TRPS1 in parotid secretory carcinoma (6/6) was higher than that of GATA3 (2/6), and the medium/high expression rate of TRPS1 in parotid adenoid cystic carcinoma (17/18) was higher than that of GATA3 (2/18). Conclusions: The expression of TRPS1 is highly sensitive to salivary gland-type breast carcinoma, especially in GATA3-negative solid subtype of adenoid cystic carcinoma, which plays an important role in clinical practice.

Warthin tumor is a benign salivary gland tumor comprising ductal epithelium and lymphoid stroma. To date, reports about the malignant transformations of intraepithelial and lymphoid components in Warthin tumor are extremely rare; lymphoid malignant transformation into B-cell lymphoma is particularly rare in combination with T-cell lymphoma. The case of Warthin tumor complicated with T-lymphoblastic lymphoma is reported to emphasize the importance of a careful light microscopic evaluation of lymphoid tissue in Warthin tumor for identifying occult lymphoma presence, reducing misdiagnosis and missed diagnosis, and determining a timely treatment.

Objective: To determine IgG antibody levels of measles, rubella, mumps in healthy population in Shanghai from 2010 to 2020 and analyze the trend of antibody changes in different age groups. Methods: 10 828 healthy people without measles, rubella and mumps in Shanghai were included in the study from 2010 to 2020. Serum samples were collected from 12 age groups, and the serum IgG antibody of measles, rubella and mumps were detected by ELISA. The difference of antibody positive rates and antibody levels were analyzed. Results: The median age M (Q₁, Q₃) of 10 828 objects were 8 years old (9 months old, 20 years old). Males accounted for 48.34% (5 234/10 828) and females accounted for 50.92% (5 514/10 828). Unknown gender information accounted for 0.74% (80/10 828), and 27.03% (2 927/10 828) of participants had unknown MMR immunization history. The total positive rates of measles, rubella and mumps IgG antibody were 76.78%, 64.46% and 64.29% and their GMCs were 541.45 mIU/ml, 31.76 IU/ml and 133.73 U/ml respectively. There were significant differences in serum IgG antibody GMC of measles, rubella and mumps in each year (F_measles=180.74, P<0.001; F_rubella=189.95, P<0.001; F_mumps=122.40, P<0.001). The positive rate of measles antibody was higher than that of rubella and mumps, and the difference was statistically significant (χ²=518.09, P<0.001). Conclusion: The level of measles IgG antibody in healthy people in Shanghai is higher, while the level of rubella and mumps IgG antibody is slightly lower.
