Overall salivary gland tumours are rare, comprising of less than 3% of overall head and neck neoplasms. Parotid gland is the most common site for the benign salivary gland neoplasm. Usually they are painless slow growing lesion involving the superficial or deep part of the gland and can severely affect the facial nerve functioning. Treatment mainly comprises of surgical excision with preservati...

OBJECTIVES To assess the value of CT perfusion imaging in the differentiation of different histological categorization of benign tumours from malignant tumours in patients with parotid neoplasms. METHODS CT perfusion was successfully performed in 62 patients with parotid neoplasms whose diagnoses were confirmed by surgery or biopsy. The software generated a tissue time-density curve (TDC) and...

Neoplasms of the major and minor salivary glands are morphologically and a clinically diverse group of neoplasms which lead the clinician to diagnostic and management challenges. This article aims to report a case of mucoepidermoid carcinoma in 83 - year - old woman who presented in the dermatology clinic with a tumour mass in the left auricular area. The patient complained of pain and abnormal...

The diagnosis of a parotid mass usually depends on thorough history taking and physical examination. Diagnostic modalities, including ultrasonographic examinations, computed tomography and magnetic resonance images, may also provide substantial information but their accuracy for diagnosis is sometimes questionable, especially in differentiating some rare neoplasms. First branchial cleft cysts (...

sialolithiasis, neoplasms and developmental disorders may be encountered in the pediatric parotid gland. These lesions may present with swelling of the parotid region, which makes diagnosis problematic. The use of imaging plays an important role in defining the location and extent of lesions and for evaluating involvement of the facial nerve, including the mastoid portion. Finally, imaging can ...

INTRODUCTION A mass in the salivary gland region often presents a diagnostic challenge with regard to its site of origin (salivary versus nonsalivary), benign or malignant nature, and tissue-specific diagnosis. The present study describes the utility of fine-needle aspiration (FNA) cytology in the diagnosis of these lesions. SUBJECTS AND METHODS Over a 6-year period (January 1994 to December ...

Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas. Myoepithelioma is usually a benign tumor arising from neoplastic myoepithelial or basket cells which are found between the basement membrane and the basal plas...

The parotid gland is the most usual location of benign neoplasms affecting major salivary glands and quite often the recurrence of these tumours is noticed, specially in the case of pleomorphic adenoma. The occurrence of multiple tumours in the parotid glands is rare and the majority of these are multifocal Warthin's tumors (papillary cystadenoma lymphomatosum). The simultaneous development of ...

BACKGROUND To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. MATERIAL AND METHODS Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. RESULTS The study sample consisted of 279 ...
