Parotid gland mass differential diagnosis

Most parotid tumors are benign with malignancy only comprising approximately 15% to 32%. 1 The typical clinical presentation is a painless mass or swelling in the cheek about the mandibular rami. Facial nerve involvement generally suggests a malignant tumor, which may present with pain or paralysis Differential diagnosis of parotid gland tumours: which magnetic resonance findings should be taken in account? Our aim was to define typical magnetic resonance (MRI) findings in malignant and benign parotid tumours. This study is based on retrospective evaluation of pre-surgical MRI of 94 patients with parotid gland tumours

The first challenge for US diagnosis of parotid gland tumors is differentiation of the clinically silent malignant tumor from benign growths 1. Med Oral. 2003 Nov-Dec;8(5):382.

PMID Aim . To create a predictive score for the discrimination between benign and malignant parotid tumors using elastographic parameters and to compare its sensitivity and specificity with standard ultrasound. Methods . A total of 124 patients with parotid gland lesions for whom surgery was planned were examined using conventional ultrasound, Doppler examination, and shear wave elastography

The parotid gland (PG) is the most common site involved in 85% of cases. PG tumors' size varies from a few millimeters to several centimeters and is about 2-6 cm on average Parotid swelling or enlargement can be unilateral or bilateral, suggesting different underlying causes Parotid tumors are abnormal growths of cells (tumors) that form in the parotid glands. The parotid glands are two salivary glands that sit just in front of the ears on each side of the face. Salivary glands produce saliva to aid in chewing and digesting food. There are many salivary glands in the lips, cheeks, mouth and throat Pathology In general, the ratio of benign to malignant tumors is proportional to the gland size; i.e. the parotid gland tends to have benign neoplasms, the submandibular gland 50:50, and the sublingual glands and accessory glands mostly malignant. Due to the size discrepancy, in absolute numbers, the parotid gland has the most tumors

Differential diagnosis of parotid gland tumours: which

Parotid gland lesions in children can be divided into benign or malignant. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children Parotid gland carcinoma is a malignant tumor of the parotid gland. Parotid gland cancers represent approximately 70% of salivary gland cancers. These are rare tumors, accounting for 3%-10% of head and neck cancers. Most tumors in the parotid gland are benign, with malignancy occurring in 15%

Salivary gland tumors are growths of abnormal cells (tumors) that begin in the salivary glands. Salivary gland tumors are rare. Salivary glands make saliva, which aids in digestion, keeps your mouth moist and supports healthy teeth. You have three pairs of major salivary glands under and behind your jaw — parotid, sublingual and submandibular Superficial/Lateral Parotidectomy: Indication: diagnostic and therapeutic excision of benign or malignant tumors that involve the superficial lobe of the parotid only.

Differential Diagnosis of Parotid Gland Tumors: Role of

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. Introduction. Parotid gland tumours account for approximately 3-6% of all head and neck tumours, with an annual estimated global incidence of 0.4-13.5 per 100,000 persons 1.About 80% of parotid tumours are benign, the most common being pleomorphic adenomas 2.Median age of onset is 45 years, with a peak of incidence for benign tumours in the fourth decade of life; for malignant tumours, the.

When encountering a cystic mass in the parotid gland, there is a wide differential list. Clearly, different considerations should be thought of if the process is multifocal or bilateral than if a solitary cyst is present. Multiple cysts without associated nodularity or complexity usually reflect a benign process Diagnosis and Treatment of Accessory Parotid Gland Tumors. 1. Benign epithelial tumors. 2. Malignant epithelial tumors. Amongst benign parotid gland tumors, polymorphous and Warthin's tumors account for 90 % of cases. Benign histopathological Type III is a basal cell gland tumor, accounting for 3-4 % of cases A mass in the neck is an extremely common clinical finding in patients of all age groups. Neck masses are often the result of inflammation caused by self-limited processes such as viral infections, although the differential diagnosis of a neck mass actually encompasses the entire spectrum of pathology from congenital to infectious to neoplastic The major salivary glands include the paired parotid, submandibular, and sublingual glands which are collectively responsible for the production of over 95 percent of saliva. In addition, there are approximately 1000 minor salivary glands dispersed through the submucosa of the oral cavity, with each measuring from 1 to 2 mm in size ( figure 1 )

The purposes of this retrospective study were (1) to clarify characteristic sonomorphologic features of tumorous lesions of the parotid gland by statistical analysis on sonographic findings and (2) to propose certain criteria for making sonographic differential diagnoses This topic discusses the clinical presentation, diagnosis, initial evaluation, and staging of salivary gland tumors. Other important topics related to salivary gland tumors include the following: (See Salivary gland tumors: Treatment of locoregional disease .) (See Malignant salivary gland tumors: Treatment of recurrent and metastatic. Background: The differential diagnosis of parotid gland tumors is often difficult with conventional magnetic resonance imaging. Purpose: To determine whether the calculation of the apparent diffusion coefficient (ADC) is valuable for making the differential diagnosis of parotid tumors. Material and Methods: Thirty parotid masses in 28 patients and 24 healthy parotid glands in 12 controls were. Parotid Tumor Diagnosis. Parotid tumors can vary in presentation and associated symptoms. Due to a variety of factors including tumor type, location, extent of disease, comorbidities, and general patient health, each case of parotid tumor must be meticulously evaluated to obtain an accurate diagnosis and customize an appropriate treatment plan Parotid gland cancer is frequently curable, especially when caught in early stages. Treatment is typically surgery, which may be followed by radiation therapy. Chemotherapy can be effective in treating later stage cancers. Emergencies related to parotid gland cancer are rare; however, parotid gland cancers are known to cause serious symptoms

sidered in the differential diagnosis of parotid tumors. The parotid lipoma is a slowly growing, asymptomatic, freely movable, soft mass. Preoperative diagnosis is generally difficult. We present a case of a slowly enlarging mass of the parotid region in a 44-year-old man that proved to be a lipomatous tumor of the parotid gland. We also revie The differential diagnosis for recurrent parotid gland swelling includes autoimmune pseudosialectasis and Mikulicz syndrome. If the former is localized to the parotid gland, it is called Mikulicz disease; there are adult and pediatric forms. If autoimmune parotitis is associated with xerophthalmia or xerostomia, it is called sicca syndrome or primary Sjögren disease The parotid gland neoplasms' differential diagnosis needs to include benign lesions like Warthin tumor, myoepithelioma, and basal cell adenoma (BCA). Additionally, malignant salivary gland tumors, including mucoepidermoid, adenoid cystic, and acinic cell carcinomas, need to be considered Cystic neck masses are commonly encountered in imaging practices and can result from a variety of entities, both benign and malignant. The most important factors in diagnosing cystic neck masses are a thorough history and physical, as the clinical presentation and patient age often determine the differential diagnosis Parotid neoplasms account for 80% of salivary neoplasms. Of parotid masses, 75% are neoplastic; the remaining 25% are nonneoplastic infiltrative processes, such as cysts and inflammation. Of parotid neoplasms, 70-80% are benign. Except for Warthin tumors, benign tumors of the parotid gland are more likely to occur in women than in men

Furthermore, benign tumors were dominate types of parotid gland tumors and there was often high FDG uptake in some benign parotid gland tumors, particularly in Warthin's tumor in parotid gland To define an algorithm for differential diagnostics of parotid malignancies and Warthin tumors (WTs) based on dynamic contrast enhanced MRI (DCE-MRI). 55 patients with parotid tumors treated.

The differential diagnosis is between a solid mass—most likely to be a lymphoma in this age group. In patients over 40 years of age, there is a possibility that such a presentation could represent a cystic metastasis from a papillary thyroid carcinoma or a cystic metastasis from a primary pharyngeal squamous cell carcinoma Introduction. A broad spectrum of pathological conditions can affect the parotid glands. Although unilateral parotid swelling is more frequently seen, bilateral parotid swelling is not uncommon. 1 Bilateral parotid swelling can result from a diverse spectrum of pathologies (), several of which do not require imaging of any kind and can be easily diagnosed clinically, whereas others can be. This article reviews the differential diagnosis of neck masses in adults and provides a framework for clinical decision-making. The tail of each parotid gland extends below the angle of the.

The differential diagnosis of SFT involving parotid gland includes a variety of spindle cell neoplasm, and many display similar histology. For example, deep benign fibrous histiocytoma may closely resemble SFT; both are well-circumscribed, contain HPC-like vessels and may express CD34 Salivary gland neoplasms comprise a variety of pathologic entities that are not seen in any other organ.1 Salivary gland tumors are relatively rare and comprise less than 3% of all tumors.2 The parotid gland is by far the most frequent salivary gland involved by tumors. Only about 20% of parotid gland tumors in adults are malignant, whereas 35%. Salivary gland tumours are uncommon, making up around 6% of head and neck tumours.They have a wide range of presentations and can be either benign or malignant. The malignant form will often affect the older patient, whilst benign salivary gland tumours have a peak onset at 40 years of age.The proportion of benign and malignant tumours between the parotid, submandibular, and sublingual glands.

In 5-14% of cases, Warthin's tumor is bilateral, but the two masses usually are at different times. Warthin's tumor is highly unlikely to become malignant. Locations. The gland most likely affected is the parotid gland. In fact, it is the only tumor virtually restricted to the parotid gland The problems of diagnosis, differential diagnosis, and surgical therapy of benign multiple parotid tumors are discussed. The current literature is reviewed. RESULTS: Synchronous multiple Warthin's Tumors or multiple tumors of different histologic types in the same parotid gland are found rarely The differential diagnosis includes mucous retention cyst, unilateral blockage of the parotid duct, benign mesenchymal tumors like lipoma, fibroma, hemangioma or neurofibroma, branchial cleft cyst, benign salivary gland tumors like pleomorphic adenoma, Warthin's tumor and malignant salivary gland tumor like muco-epidermoid tumor [3, 6] Intraglandular lipoma of the parotid gland should be included as a rare possibility in the differential diagnosis of tumours involving the parotid gland. The extent of surgery should be determined at the time of operation with dual goals of complete mass resection, including normal tissue and facial nerve preservation Symptoms. Parotid Gland Tumor is more common in the distal portion of the gland presenting as a discrete mass. The abnormal growth typically presents as slow-growing, solitary, unfixed neoplasm in the parotid area, although some are multinodular and fixed. Symptoms in most patients occur in a duration of less than a year up to several decades

For many people with parotid gland tumors, surgery performed by a head and neck surgeon is the main treatment. This operation is called a parotidectomy. The parotid gland consists of two lobes: the superficial lobe and the deep lobe. Surgery to remove a tumor in the superficial lobe is called a superficial parotidectomy The frequency of malignant lesions varies by site. Approximately 20% to 25% of parotid tumors, 35% to 40% of submandibular tumors, 50% of palate tumors, and more than 90% of sublingual gland tumors are malignant.[1,9] Histopathology. Histologically, salivary gland tumors represent the most heterogenous group of tumors of any tissue in the body Although pleomorphic adenomas most commonly occur in the parotid gland, it may also be encountered in the submandibular, lingual, and minor salivary glands. Pleomorphic adenoma is the most common tumor in these glands, even though almost half of the tumors found in the minor salivary glands are malignant

Parotid Tumor - Causes, Symptoms, Diagnosis, Surger

In about 20% of cases, the tumor is in fact extra-parotid but it is so large that it obliterates the fat plane by compression or it originates from the gland capsule. In the very rare case of extraparotid tumor with parotid gland invasion, the differential diagnosis should include minor salivary gland tumors, neuromas and glomus tumors PNET of the parotid gland. Case report: A-33-year-old woman presented with a recurrent rapidly growing mass in the left parotid of 12 months duration associated with facial asymmetry. She had an excision of this mass in another institution since 6 months. The initial histological examination showed a benign mixed tumor of the salivary glands.

The mean elasticity score for benign tumors was 2.75 6 0.95, and for malignant tumors it was 3.44 6 0.85 (P =.034). Conclusions-According to our results, real-time strain sonoelastography seems to have additional value over routine sonographic evaluation of parotid gland tumors in the differential diagnosis of benign and malignant parotid masses The tumor was diagnosed as a DSRCT of the right parotid gland. The patient has been followed for 3 years without recurrence or metastasis. Although DSRCT in the salivary gland is extremely rare, it should be included in the differential diagnosis of poorly differentiated salivary gland neoplasms, especially with a fibromyxoid background Introduction. Parotid tumors account for 70-80% of salivary gland tumors. 1,2 Pleomorphic adenoma (PA) and Warthin tumor (WT) are the two most common benign tumors of parotid gland.
