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 (...

Background. Kaposi’s sarcoma (KS) as one of the defining tumours of AIDS, was described as multiple slowly progressing pigmented skin plagues and as vaso-formative lesion in microscopic finding. Several forms of the disease have been suggested, such as mucocutaneous and lymph nodal. KS is rarely seen in the major salivary glands. Furthermore, KS of parotid tissue or intra-parotid lymph node is ...

Lymphoepithelial carcinoma of the salivary glands is a rare neoplasm that is characterized by a non-neoplastic lymphocytic infiltration associated with an epithelial proliferation. It involves mainly the parotid gland. Racial and geographical factors contribute to the pathogenesis of this tumor. We report a case of a 70-year old woman from a non-endemic area who presented with several months hi...

Myxofibrosarcoma has been recently described as a distinct histological entity and commonly affects the extremities and trunk of the elderly. It is, however, rare in the head and neck (2.8%) region, and we are unaware of any reports of it presenting as a parotid mass. The epitheloid variant accounts for less than 3% of myxofibrosarcomas. We report a case of a 78/F presenting with an epitheloid ...

It is difficult to distinguish nodular fasciitis (NF) from other neoplasm of the parotid gland, especially pleomorphic adenoma (PA) by fine needle aspiration cytology. A 39-year-old female noticed a mass in the parotid region. The aspirate material showed cohesive parts composed of the cells that had oval or spindle-shaped nuclei and relatively abundant cytoplasm and some cells with plasmacytoi...

Sialadenoma papilliferum is a rare benign salivary gland tumor. We present an unusual case of sialadenoma papilliferum of the parotid gland, discuss clinical presentation, diagnostic challenges, and review of the literature. A 65-year-old male smoker presented with a large, exophytic, fungating, painless mass in the tail parotid for 8 years. The tumor developed an exophytic component 2 years be...

OBJECTIVE Wegener's granulomatosis is a systemic vasculitis characterized by necrotizing granulomatous lesions mostly involving the upper and lower respiratory tract. The disease rarely causes parotid gland involvement and pneumothorax. We report a case of Wegener's granulomatosis involving parotid gland, and complicated with a pneumothorax. CLINICAL PRESENTATION A 45-year-old man admitted wi...

A 49-year-old female presented to our department with right infra-auricular swelling present for more than 3 weeks. The patient’s medical history was not remarkable. The patient had no fever, cough, stridor, dyspnea, shortness of breath, rash, and dryness of mouth or eyes, weight loss, convulsions, or previous hospital admissions. The family history was unremarkable. Physical examination reveal...

The purpose of this study was to determine the incidence of an anterior extension of the parotid gland, such as an accessory parotid gland (APG) or facial process (FP) and to evaluate its characteristics on computed tomography (CT) scans. We reviewed CT scans of 1,600 parotid glands from 800 patients. An APG on CT was defined as a soft-tissue mass of the same density as the main parotid gland, ...
