INTRODUCTIONClear cell carcinoma is a rare low-grade carcinoma that almost exclusively occurs in the minor salivary glands. This tumour is one of the new additions in the recent World Health Organization (WHO) classification of salivary gland tumours.

CLINICAL PICTUREA 50- year-old woman presented with a gradually enlarging painless submucosal mass of 3 months' duration over the left side of the palate.

TREATMENT AND OUTCOMEA preoperative diagnosis of primary clear cell carcinoma of salivary gland with focal surface epithelial dysplasia was rendered after thorough clinical examination to rule out renal origin. The lesions were excised with wide surgical margins and 3 years into the postoperative period, the patient was disease-free.

CONCLUSIONWe report a case of clear cell carcinoma of intra-oral minor salivary gland and draw comparisons with metastatic clear cell carcinoma of renal origin.

Objective: To investigate the clinicopathological, immunophenotypic, and molecular genetic features of bronchial sialadenoma papilliferum (BSP). Methods: Four cases of BSP collected at the Shanghai Pulmonary Hospital from May 2018 to June 2021 were retrieved and analyzed. These cases were evaluated for their clinical, histological, immunohistochemical (IHC) and genomic features. The patients were followed up and relevant literature was reviewed. Results: All four patients were male, aged from 55 to 75 years (mean 62 years), with tumor diameter of 6 to 21 mm (mean 13.5 mm), and lesions were located in the left lower lobe (n=2), right lower lobe (n=1), and trachea (n=1). They were characterized by a combination of surface exophytic endobronchial papillary proliferation and an endophytic two-cell layered ductal structure. IHC staining showed that CK7 and EMA were strongly positive in ductal epithelium; p63, p40, CK5/6 were positive in ductal and papillary basal cells; SOX10 was positive in ductal epithelium and basal cells; S-100 was positive in basal cells and ductal epithelium in two cases. Next generation sequencing showed that two cases harbored BRAF V600E mutation. Conclusions: BSP is an extremely rare primary lung tumor arising from the salivary gland under bronchial mucosa. The primary treatment choice of this tumor is complete surgical resection. The diagnosis and differential diagnosis of this tumor depend on classic histomorphologic and IHC features, and BRAF V600E gene mutation can be detected.

We report a surgical case of primary polymorphous low-grade adenocarcinoma (PLGA) of the minor salivary gland-type of the lung. A PLGA originating from the right upper lobar bronchial inlet was successfully treated by sleeve right upper lobectomy. PLGAs are thought to be indolent tumors that are preferentially localized to the palate, and they affect the minor salivary glands almost exclusively. Until now, two cases of distant metastases to the lung have been reported in the English literature. To the best of our knowledge, only one case of PLGA of minor salivary glandtype of the lung without evidence of a previous oropharyngeal primary tumor has been reported in the English literature. But the case was not a single lesion; it was bilateral tumors accompanied by tumors of the cervical lymph nodes. We report here the first case of a single primary PLGA of the minor salivary gland-type of the lung, which was successfully treated by sleeve bronchial resection of right upper lobe.

A 67-year-old male patient was admitted because of "the right side nasal obstruction repeatedly for 4 years". He got nasal obstruction 4 years ago, especially for the right side nasal cavity, sometimes got blood in his nasal discharge, then the symptom relieved after accepting treatment in local hospital. During the 4 years, the symptom repeatedly occurrence. Three days before hospitalization, the CT examination indicated abnormal things in his nasal cavity and the bone of his nasal sinus had been destroyed. Some abnormal organism were sent to pathological examination, and the report indicated it is acinic cell carcinoma of salivary gland. During the nasal endoscope surgery, a red goiter was found in his nose with its surface crude and brittle. Then we cut the goiter by nasal endoscope, during the operation we find the bottom of the goiter is on the nasal septum. Two weeks after the operation, the patient received the radiation therapy. One year after the operation he doesn't get the abnormal symptom and the nasal MRI not found recidivation.

AIMTo detect the expression of nerve growth factor (NGF) and vascular endothelial growth factor (VEGF) in salivary adenoid cystic carcinoma (SACC) tissues, as well as to determine the correlation between growth factor expression and prognosis in SACC.

METHODOLOGYMedical records of 63 patients surgically treated for SACC between January 1988 and October 2005 were reviewed. Immunohistochemistry was performed to examine the expression of NGF and VEGF in tumor tissues. Kaplan-Meier analysis and Cox's proportional hazard regression model were applied to assess predictors of survival.

RESULTSNGF and VEGF were overexpressed in SACC tissues, compared with those in normal salivary tissues (P < 0.05), and the staining intensity of these two factors was stronger in groups of solid subtype, advanced TNM stage, perineural invasion and recurrence. Patients with high-expression of NGF and VEGF, solid subtype, advanced stage, perineural invasion, recurrence and extended resection alone had worse survival rates (P < 0.05).

CONCLUSIONNGF and VEGF are expressed increasingly in the tissues of SACC cases with invasion and metastasis. NGF expression and VEGF expression are independent

The presence of a malignant mixed tumor, also known as a carcinosarcoma, in the salivary gland is very rare. Such mors, which are typically aggressive, are characterized by the presence of carcinomatous and sarcomatous components. 9-year-old neutered female domestic short-haired cat presented with swelling in the right mandibular lesion that had rapidly enlarged over the previous 3 weeks. Physical examination revealed a large, fluctuated and painless subcutaneous swelling that was associated with a firm mass. Radiographs of the head revealed a soft-tissue density that involved faint circular calcific opacity. Contrast-enhanced computed tomography revealed that the peripheral capsulated cystic area had a contrast enhanced region without bone lysis. The cat received a total excision of the mass and postoperative radiotherapy. Histopathological analysis of the mass revealed that it was a malignant mixed tumor. Metastasis to the lung was discovered 7 weeks later, at which time treatment was stopped.

OBJECTIVEThe pathologic slides and clinical data of 119 patients with mucoepidermoid carcinoma (MEC) of salivary glands were reviewed. All patients underwent surgical therapy in Department of Oral and Maxillofacial Surgery, College of Stomatology, Fourth Military Medical University. The postoperative overall observed survival rates and specific survival rates were statistically caculated, and the correlative clinicopathologic factors influencing the prognosis were evaluated.

METHODSStatistical analysis was performed using the SPSS 10.0 software. The survival rates were obtained by the Kaplan-Meier method. The clinicopathologic parameters were evaluated using log rank test (univariate analysis) and Cox proportional hazards regression model (multivariate analysis).

RESULTSThe overall observed survival rates of this group were 92.53%, 87.52% and 85.39% at 5, 10 and 15 years respectively after surgical therapy. Univariate analysis demonstrated that the factors correlated with lower in survival rates were patient's age (> or = 40 years), advanced clinical stage (TNM III, IV stage) and the poorly differentiated tumors (P < 0.05). The survival rates of male patients with MEC in the major salivary glands were significantly lower than those of female patients (P = 0.008). The degree of differentiation, TNM stage and preoperative symptoms were three important prognostic factors that were selected into the Cox proportional hazards regression model.

CONCLUSIONSMost patients with highly differentiated MEC in salivary glands had a favorable outcome after receiving adequate surgical treatment. The degree of differentiation and the TNM stage of MEC in the salivary glands are two useful factors to evaluate the prognosis of these neoplasms.
