Different surgical options are currently available for treating benign tumors of the parotid gland, and the discussion on optimal treatment continues despite several meta-analyses. These options include more limited resections (extracapsular dissection, partial lateral parotidectomy) versus more extensive and traditional options (lateral parotid lobectomy, total parotidectomy). Different schools favor one option or another based on their experience, skills and tradition. This review provides a critical analysis of the literature regarding these options...

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imaging localized the lesion to the superficial lobe of the parotid gland, suggesting a neurofibroma. Cosmetic disfigurement and a functional deficit led us to perform complete surgical resection...

The ganglioneuroblastoma is a rare form of pediatric tumor, involving innerved tissues of the nervous sympathetic system, whose evolution is very hard to foresee. A 38 year-old patient whose histologic exam unexpectedly showed ganglioneuroblastoma, underwent a parotidectomy. Three years after surgery the patient is in optimal clinical conditions, without any radiological signs or clinical relapses. KEY WORDS: Ganglioneuroblastoma, Parotid gland, Parodidectomy.

OBJECTIVES: The aberrant expression of mucins and mucin-type carbohydrates has been described in many types of cancer, including mucoepidermoid carcinoma (MEC), a malignant salivary gland tumor. In this study, we examined the aberrant expression patterns of mucins (MUC1, MUC4, MUC5AC and MUC5B), simple mucin-type carbohydrate antigens (Tn, sialyl-Tn and T) and mature carbohydrate antigens (Lewis(a) and sulfo-Lewis(a) antigens) in MEC originating from the parotid gland, which normally does not secrete mucins...

Pleomorphic adenoma is a slow-growing salivary gland tumor frequently arising from the parotid gland. In this study, we investigated the role of the insulin-like growth factor I-II receptor (IGFI-IIR) levels on the development of parotid gland pleomorphic adenomas. The study included 20 males and 20 females who had superficial parotidectomy with a histopathological diagnosis of pleomorphic adenoma in Fırat University Otorhinolaryngology Clinic between 2000 and 2011. The ages of the patients ranged between 20 and 50 years...

The aim of the study is to define the utility of ultrasound (US) in differentiating benign from malignant parotid tumors as well as pleomorphic adenomas (PA) from monomorphic adenoma (MA). Seventy-two consecutive parotid gland tumors were analysed with high-resolution ultrasonography (12 MHz) with color Doppler imagining. The histopathological diagnosis was confirmed after parotidectomy for each lesion. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for the US were established...

REVIEW
A Agaimy, H Iro, J Zenk
Salivary gland tumors and tumor-like lesions in the pediatric population are uncommon. They comprise a heterogeneous group of infectious/inflammatory and neoplastic conditions. Pediatric salivary neoplasms include benign tumors of mesenchymal or epithelial origin as well as malignancies of epithelial (carcinomas), mesenchymal (sarcoma) or hematolymphoid (lymphoma) derivation. Infectious/inflammatory conditions and hematolymphoid malignancies may represent either genuine parenchymal pathology or conditions involving intraglandular lymph nodes of the parotid glands (intraglandular lymphadenopathy and intraglandular nodal lymphomas)...

Acinic cell carcinoma with high-grade transformation of the salivary gland is an unusual variant with less than fifty cases being reported in the literature. It is characterized by a low- and high-grade component juxtaposed with one another and tends to take on a more aggressive clinical course than its low-grade counterpart, suggesting a poor clinical outcome. We, hereby, report a case of acinic cell carcinoma in a 48-year-old woman with a 6-month history of a right parotid facial swelling rapidly increasing in size...

BACKGROUND: Myoepitheliomas account for less than 1% of salivary gland tumors. They mostly affect the parotid glands of adults during the third to fifth decades. CASE PRESENTATION: A 10-year-old Indian boy reported a small swelling in the roof of his mouth of 10 days' duration. History revealed that the lesion was painless and not associated with bleeding or pus discharge. On examination, a purplish well-circumscribed growth was noted on his posterior hard palate...

Lymphoepithelial carcinoma is a variant of undifferentiated carcinoma with characteristic dense lymphoid stroma in which nasopharynx is site of predilection. Racial and geographic association and Epstein-Barr virus positivity in endemic areas are other characteristics of this rare neoplasm. Lymphoepithelial carcinoma accounts for only 0.4% of malignant salivary gland tumors. The authors present a patient with Epstein-Barr virus positive lymphoepithelial carcinoma of the parotid gland in a nonendemic region...

We report a rare case of low-grade intraductal carcinoma with tumor-associated lymphoid proliferation (TALP) in the parotid gland of a 75-year-old woman. Grossly, the tumor was solid and cystic. Histologically, the tumor consisted of a papillary-cystic, micropapillary, or focally cribriform proliferations of epithelial cells with low-grade cytological atypia. The interspaces between the epithelial components were filled with prominent lymphoid stroma and lymphoid follicles, superficially mimicking Warthin tumor...

Epithelio-myoepithelial carcinoma (EMEC) is a very rare malignancy of the salivary gland which comprises less than 1 % of salivary gland tumors. In the parapharyngeal space they can either arise from the deep lobe of parotid gland or de novo from minor salivary glands. We present a case of epithelio-myoepithelial carcinoma of parapharyngeal and masseteric space. The case is important for its rarity of presentation and we discuss the surgical difficulties and morbidities.

Malignant non-basaloid tumors that arise from basal cell adenoma (BCA) are extremely rare. The patient was a 72-year-old Japanese male, who had noticed swelling of the left parotid region 21 years ago. A superficial lobectomy was performed. About 60% of the tumor was made up of cribriform and trabecular tissue composed of basaloid cells, which exhibited mild atypia and nuclear expression of β-catenin. This portion of the tumor was considered to be a BCA. In the other part of the tumor, the proliferation of large eosinophilic atypical cells, most of which formed intraductal structures, was observed...

OBJECTIVES: Preferential use of fine-needle aspiration (FNA) versus core needle biopsy (CNB) for distinguishing benign from malignant major salivary gland tumors is highly debated. The main disadvantage of FNA is lower sensitivity, whereas arguments against CNB include use of a larger bore needle and greater risk of complications. The aim of this study is to evaluate our experience performing ultrasound-guided (UG) FNA with selective use of CNB based on preliminary cytopathology, and to determine whether our preoperative diagnostic approach is more sensitive and specific than FNA alone-and at least as sensitive and specific as CNB alone...

We undertook a re-analysis of the Canadian data from the thirteen-country INTERPHONE case-control study (2001-2004), which evaluated the association between mobile phone use and risk of brain, acoustic neuroma, and parotid gland tumors. The main publication of the multinational INTERPHONE study concluded that "biases and errors prevent a causal interpretation". We applied a probabilistic multiple-bias model to address possible biases simultaneously, using validation data from billing records and non-participant questionnaires as information on recall error and selective participation...
