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, located at the anterior part of the main parotid gland, and completely separate from the main parotid gland. An FP was defined as a lobe of the parotid gland protruding anteriorly over the anterior edge of the ramus of the mandible on CT and showing continuity with the main gland...

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected...

Salivary Duct Carcinoma (SDC) is a distinctive and clinically aggressive adenocarcinoma of salivary origin. It arises from the ductal epithelium, predominantly occurring in the major salivary glands, especially the parotid gland. Here, we report a case of an extensive salivary gland pathology involving the right side of face, possibly arising from the parotid gland in a 25-year-old male patient. On routine histopathology, the tumour mass revealed a papillary pattern of neoplastic ductal epithelial cells showing comedo-like-central necrosis...

Adenomatous ductal proliferation/hyperplasia (ADP/H) of the salivary gland, a rare asymptomatic nonneoplastic lesion that histopathologically resembles basal cell adenoma, is typically incidentally identified in resected specimens of other salivary diseases such as tumors and chronic sialadenitis. A 70-year-old male was referred to our hospital with a 9-month history of continuous swelling in the left parotid region. A physical examination revealed a soft mass in the left parotid gland, which was identified as a cystic mass by computed tomography...

Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy. Recent studies have shown that most MECs harbor gene fusions involving MAML2-an alteration that appears to be specific for MEC, a finding that could be diagnostically useful. While most cases of MEC are histologically straightforward, uncommon variants can cause considerable diagnostic difficulty. We present 2 variants of MEC for which MAML2 studies were crucial in establishing a diagnosis: a previously undescribed ciliated variant, and the recently described Warthin-like variant...

Myoepithelioma is defined as myoepithelial cells composed of tumor with solid, myxoid, and reticular growth pattern by the World Health Organization. It is a rare neoplasm that arises in the major salivary gland or minor salivary gland comprising approximately 1% of all salivary gland tumor. This neoplasm occurs in the parotid gland and soft palate mostly, which can be found in other organs. However, up to now, myoepithelioma of nasal septum has not been reported in English medical literature. Histologically, it is grouped as spindle, epitheliod, reticular, and clear cell types...

Two dogs with previous parotid duct transpositions presented with unrelated ocular disease. In both cases, ophthalmic examination revealed the need for enucleation or exenteration. In case 1, systemic coccidioidomycosis was diagnosed with panuveitis and secondary glaucoma of the left eye. In this case, the parotid duct was ligated at the time of enucleation to stop salivary secretions. This dog encountered morbidity in the form of a sialocele that did not resolve for 11 months. In case 2, ultrasound and computed tomography revealed a discrete mass within the left medial orbit that was suspected to arise from the nictitating membrane...

This is a case of a 62-year-old woman with a remote history of acinic cell carcinoma of the parotid gland, who presented with a palpable vaginal mass, anterior vaginal wall prolapse, and stress urinary incontinence. A 2 cm firm mobile mass on the anterior vaginal wall was found on clinical examination. A computed tomographic scan revealed a mass between the vaginal vault and bladder that was eventually surgically excised. The histology, supported by the immunohistochemistry, revealed metastatic acinic cell carcinoma to the vagina after 37 years of her initial diagnosis...

OBJECTIVES: Preoperative fine needle aspiration (FNA) of parotid lesions often is used in the initial evaluation of parotid masses, but its role in guiding surgical decision making remains unclear, in part due to varying diagnostic accuracy reported. We sought to evaluate the role of preoperative FNA in detection of malignancy and impact on surgical management. STUDY DESIGN: Retrospective study. METHODS: The medical records of patients who underwent parotidectomy at a single tertiary medical center were reviewed from 2000 to 2015...

Schwannomas are benign tumours that originate from the myelin sheath of peripheral nerves. They are characterised by a slow growth tendency. Benign schwannomas represent 35% of the head and neck district tumours. Hypoglossal schwannomas account for 5% of non-vestibular schwannomas, and malignant schwannomas occur very rarely. In the present case report, the case of a 49-year-old man who presented with paraesthesias in the left parotid and submandibular region, associated with sensation of foreign bodies and dysphagia for solids, is described...

A 15-year-old boy was diagnosed with a cystic parotid mass, which was initially thought to be a first branchial cleft cyst. The mass was treated with antibiotics and fully resolved on examination and imaging. The mass returned, and a superficial parotidectomy was performed to remove the suspected branchial cleft cyst. Final pathology demonstrated a B-cell lymphoblastic lymphoma. Bilateral bone marrow biopsies and peripheral blood counts were negative for any malignancy. This case demonstrates a rare presentation of primary parotid B-cell lymphoblastic lymphoma that began as a fluctuating cystic parotid mass consistent in appearance with a first branchial cleft cyst...

Warthin-like mucoepidermoid carcinoma is a recently proposed variant of musoepidermoid carcinoma. Histologically, it is characterized by its close resemblance to Warthin tumor, including dense lymphocytic infiltration, flattened intermediate epithelium resembling squamous metaplasia, and cystic change. Given its histologic similarity to Warthin tumor, confirmatory testing for MAML2 rearrangement is often required for this diagnosis. Here we present the first cytologic reports of two 53-year-old female patients with parotid masses...

A 41-year-old patient was hospitalised for a chronic right parotid mass. A cervical ultrasound revealed a cystic mass of the parotid. Cervical MRI found a ductal ectasia of the parotid and submandibular glands associated with a retention cyst of the right parotid. He had a right total parotidectomy. Histopathological examination of the lesion revealed a multilocular cystic mass with a diffuse glandular ectasia of salivary ducts. The patient had an uneventful postoperative course without any recurrence of symptoms...

Parotid gland tuberculosis is an uncommon manifestation of one of the most common infections even in the developing countries, caused by Mycobacterium tuberculosis. There are no specific symptoms or clinical signs of parotid tuberculosis, and such an infection most commonly presents as a slow growing painless parotid mass. Because of its rarity, tuberculosis of parotid gland is often mistaken for a malignant growth, and it most commonly gets diagnosed after superficial protidectomy. Complete cure is possible with standard antituberculous therapy...

One case of intraductal carcinoma of the parotid gland in a 67-year-old male patient is here introduced. The patient, who had a one-year history of a parotid mass, had undergone ultrasound and MRI examination that disclosed a 13x4x3 mm well delimited nodular mass of the accessory lobe of his left parotid gland. Ultrasound-guided Fine Needle Aspiration (FNA) had been performed by the clinician. The obtained smears showed widespread cellular necrosis in which cellular clusters with moderate and focally severe atypias displayed papillary and cribriform architecture and were admixed with sheets of epithelial cells with less striking nuclear atypias, squamous, or apocrine metaplasia...

Orbital involvement in systemic sarcoidosis is a rare condition. We report a case of orbital sarcoidosis with bilaterally huge lacrimal gland involvement as the initial manifestation of systemic sarcoidosis. A 20-year-old woman admitted the ophthalmology department with progressive bilateral upper eyelid swelling for 6 months. The only pathologic finding was the presence of bilateral, symmetrical, solid, lobular masses at the lateral upper eyelids at the location of lacrimal glands. On systemic examination, bilateral parotid and submandibular glands appeared swollen...
