Parotid Gland Tumor

Background: The parotid glands are the largest salivary glands in humans and are frequently involved in various primary & systemic disease processes. The most common benign parotid gland tumor is pleomorphic adenoma. Around 20% of parotid tumors are malignant with most common parotid tumors being mucoepidermoid carcinoma and adenoid cystic carcinoma. Objective: To determine the diagnostic accuracy of pulsed and color Doppler for the evaluation of parotid gland cancer.   Methods: It was a cross sectional study by design carried out in Department of Radiology and Department of Maxillofacial Surgery, Mayo Hospital – Lahore in a duration of three year. All the patients were examined with mind-ray 7.5 MHz linear transducer. There are three methods used collectively; Grey Scale, color Doppler and Pulsed Doppler in sonographic examination. Color Doppler and pulsed Doppler demonstrate number of blood vessels within the tumor, their Peak Systolic Velocity and Resistive Index respectively. Histo-pathological results were correlated post operatively with the data obtained from Doppler ultrasound. Data was analyzed using SPSS 23.0   Results: In this study, 192 patients were included .The mean age was 39.42 ± 11.93 years. 58.85% (112) were male patients and 41.15 %( 80) patients were females. The solid masses with regular margins were evaluated and the diagnostic accuracy of pulsed Doppler was found to be 87.5% taking histopathology as gold standard.   Conclusion: This study shows pulsed Doppler to be more accurate tool for diagnosis of parotid gland tumor as compared to color Doppler taking histopathology as gold standard.

Parotid Gland Tumor

Introduction: Tumors of the salivary gland are relatively uncommon and represent less than two percentage of all head and neck neoplasms. Parotid gland tumor comprises 85% of the salivary gland tumors of which 80% are being benign. Superficial parotidectomy is the commonest procedure done for parotid tumors which can be performed by either anteretrograde or retrograde facial nerve dissection technique.Methods: Outcome of 60 patients after superficial parotidectomy with retrograde facial nerve dissection has been studied.Results: Total of 60 patients had been studied. Complications like facial nerve weakness, Freys syndrome, salivary fistula, and wound infection were taken into account. Among them, 13.33% patients developed temporary facial nerve weakness, followed by temporary salivary fistula, 1.6%. None of the patients developed any severe complication.Conclusion: Superficial parotidectomy by retrograde facial nerve dissection is an easy technique to carry out with low complication rate and without compromising surgical outcome.Journal of Gandaki Medical CollegeVol. 10, No. 1, 2017, page: 25-27

Abstract Objectives Carcinosarcomas of the salivary gland are rare neoplasms and have been described arising de novo or in association with pleomorphic adenoma (PA). PLAG1 and HMGA2 translocations are known to occur in PAs and carcinomas ex PA but are mutually exclusive. Methods We report a case of a carcinosarcoma in the parotid gland of a 77-year-old man with unusual anaplastic sarcomatoid giant cell morphology. Results Microscopically, a small separate PA was found adjacent to the carcinosarcoma. By conventional notion, the PA and carcinosarcoma would be considered related, as carcinosarcomas are well known to arise from PAs (carcinosarcoma ex PA). However, fluorescence in situ hybridization (FISH) assay demonstrated PLAG1 translocation in the carcinosarcoma and HMGA2 translocation in the separate PA. Conclusions These findings support that the carcinosarcoma likely originated from another PA with a PLAG1 translocation or de novo but not from the coexisting PA harboring a different translocation. To our knowledge, the case is the first to demonstrate PLAG1 translocation by FISH in a sarcomatous component of any parotid gland tumor, which may help better classify these tumors. In addition, multiple PAs are commonly found in the salivary gland, and to our knowledge, our case is the first to demonstrate that the same parotid gland can host PAs and PA-related tumors with different translocations.

Castleman disease is a rare lymphoproliferative disease occurs most often in lymph nodes located in the chest. The extra-nodal form concerns 25% of diagnosed cases of this disease entity. We present the case of Castelman disease localized in the parotid gland in a 15-year-old boy, confirmed by histopathological examination, clinically progressing as a right parotid gland tumor.

Pleomorphic Adenomas

The anti-apoptotic protein Mcl-1 is highly expressed in various types of malignant tumors. Overexpression is reported to correlate with poor prognosis and disease progression. We report the expression levels of Mcl-1 in tumor samples of the parotid gland. A retrospective study containing 108 patients was performed. A tissue microarray of six malignancies of the parotid gland and pleomorphic adenoma as control was constructed. Parotid gland tumor samples were immunohistochemically stained for Mcl-1 and expression intensities were assessed. Statistical analysis included correlation to patients' clinical data and comparison of malignancies to the adenoma.All malignancies had significantly higher expression of Mcl-1 than the pleomorphic adenomas. The intensity, however, had no significant correlation to overall survival.Our immunohistochemical findings indicate that parotid gland malignancies produce high levels of Mcl-1 protein. Therefore, Mcl-1 might serve as a predictive co-marker in tumors of the parotid gland.
