BACKGROUND: Oncocytoma or oxyphilic adenoma is uncommon salivary gland tumour, occurs predominantly in the in patients older than 60 years of age. Clinically oncocytoma resemble other salivary tumours while histology is typically consisting of oncocytes with many hyperplastic mitochondria. It usually occurs in the parotid gland. Because the features of oncocytoma are similar to those of other benign and low-grade malignant salivary tumours, clinical diagnosis is often challenging.CASE PRESENTATION: This report presents the pathologic and imaging findings of an oncocytoma arising in the deep lobe of the right parotid gland in a 74-year-old male. Oncocytoma was diagnosed on the basis of histological, magnetic resonance imaging (MRI), scintigraphic findings and fine needle aspiration cytology (FNAC).CONCLUSION: This case was unique because in the literature there are few articles about the rare presentation and deep lobe location of this type of parotid oncocytoma.

AbstractObjectivesThis study focused on parotid gland tumours diagnosed as benign by fine-needle aspiration cytology and investigated the necessity of frozen section biopsy.MethodsThere were 104 cases of parotid gland tumour where fine-needle aspiration cytology was benign and frozen section biopsy was subsequently performed, between April 2006 and June 2016. In this retrospective study, the results of frozen section biopsy were analysed and compared with the final histological diagnosis.ResultsAmong the 104 cases diagnosed as benign by fine-needle aspiration cytology, 102 cases and 2 cases were diagnosed as benign and malignant, respectively, by frozen section biopsy. The final histological diagnoses showed that 98 cases were benign and 6 cases were malignant. The sensitivity and specificity values of frozen section biopsy in detecting malignant tumours were 33 per cent and 100 per cent, respectively.ConclusionThe necessity of frozen section biopsy in cases with benign fine-needle aspiration cytology may be low in parotid gland surgery.

Thymoma is the most common tumor of the anterior mediastinum with an incidence of 0.15 cases per 100,000. Ninety percent of all thymoma occur in the anterior mediastinum, with the remainder occurring in the neck or other mediastinal areas. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue and is caused by the aberrant migration of the embryonic thymus. ECTs are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Intrathyroid epithelial thymoma is a rare tumour comprising about 0.08% of all primary thyroid malignancies. It is low-grade thyroid carcinoma with squamous cell differentiation whose overall survival rate was found to be 71%. Here we presented a case of 43 year old female, came with swelling in front of the neck since many years. Ultrasound neck and fine needle aspiration cytology (FNAC) was performed. Patient underwent total thyroidectomy and specimen obtained was sent for histopathological examination. It revealed ectopic intrathyroid thymoma.

Aims: To evaluate the pre-surgical diagnostic value of Multiparametric Ultrasound (MPUS) and Fine Needle Aspiration Cytology (FNAC) in differentiating parotid gland tumors, comparing the results with histology. Materials and methods:The study enrolled 84 patients with parotid gland lesions surgically treated in a single tertiary center and evaluated by MPUS. Each patient underwent FNAC. Histological examination was considered the gold standard. Results: Histology identified 62 benign tumors and 22 malignancies. In the differential diagnosis between malignant and benign lesions, B-mode Ultrasound (US), Color-Doppler US, Contrast-Enhanced US (CEUS), Elastography (USE) and FNAC showed the following values of sensitivity: 82%, 81%, 86%, 77%, 73% respectively; specificity: 97%, 61%, 95%, 71%, 97% respectively; PPV: 90%, 43%, 86%, 50%, 89% respectively; NPV: 93%, 90%, 95%, 88%, 91% respectively; and accuracy: 89%, 71%, 90%, 78%, 84% re-spectively. Conclusions: CEUS proved to be a valid and accurate method for identifying malignant tumors of parotid gland; the combination of B-mode US with CEUS showed similar diagnostic accuracy, but better sensitivity than CEUS taken alone. USE did not improve the diagnostic performance of the B-mode US, alone or in association with CEUS; however, it revealed the highest diagnostic accuracy in the differentiation between benign lesions. FNAC demonstrated lower values in comparison with CEUS and with USE. Therefore, according to our study, MPUS could be proposed as a valid alternative to FNAC.
