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...

Compounds activating γ-aminobutyric acid type A receptor were isolated from the toad Bufo bufo venom as a result of chromatographic separation. Analysis of the structure of these compounds by mass spectrometry and nuclear magnetic resonance showed that they are arginine derivatives of dicarboxylic acids and represent suberylarginine, pimeloylarginine, and adipoylarginine.

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...

BACKGROUND: Suprahyoid neck lesions are difficult to assess only by means of clinical inspection and therefore imaging techniques are required to precisely evaluate suprahyoid neck spaces. The aim of this study was to evaluate the distinctive role of computed tomography in the assessment of anatomical source and pathological type of masses involving the suprahyoid neck spaces. MATERIAL/METHODS: Sixty patients presenting with suprahyoid neck masses underwent computed tomography of the neck...

BACKGROUND: Shear wave elastography is a relatively new method of quantitative measurement of tissue elasticity. Assuming that malignant lesions are stiffer than benign ones, elastography may provide supplementary information for their discrimination. However, potential confounding factors impacting tissue stiffness should be investigated first. AIMS: The objective of this study was to measure the stiffness of selected tissues of the head and neck in a normal population and to evaluate its relationship to age, sex, and body mass index...

BACKGROUND: Anatomical knowledge of the facial vasculature is crucial for successful plastic, reconstructive, and minimally invasive procedures of the face. Whereas the majority of previous investigations focused on facial arteries, the precise course, variability, and relationship with adjacent structures of the facial vein have been widely neglected. METHODS: Seventy-two fresh frozen human cephalic cadavers (32 male and 40 female cadavers; mean age, 75.2 ± 10...

Sclerosing mucoepidermoid carcinoma of the salivary gland (SMEC) is a rare subtype of mucoepidermoid carcinoma (MEC), first described in 1987 by Chan and Saw. As far as we are aware, only 30 cases have been published since then. Most cases were located in the parotid gland with some cases described in the submandibular and minor salivary glands. SMEC typically presents as a long-standing mass, with a non-specific enhancing appearance on imaging and is often non-diagnostic on fine needle aspiration, making pre-operative diagnosis very difficult...

To compare the projectional surface anatomy of healthy individuals in an adult population with those with a thyroid mass, using computed tomography (CT). Sixteen slice CT images of 101 individuals were analyzed using a 32-bit Radiant DICOM viewer to establish the relationships among major anatomical landmarks in the neck and their vertebral levels. The structures investigated included: hard palate (HP), hyoid bone (HB) including body and lesser horns, soft palate (SP), thyroid gland (TG) (both superior and inferior poles), thyroid gland anteroposterior (APD) and superoinferior (SID) diameters, thyroid isthmus (TI) superoinferior dimension, epiglottis, vertebral arteries (right and left), and both right and left parotid glands (superior and inferior extents)...

Low-grade cribriform cystadenocarcinoma (LGCCC) is a rare tumor of the salivary gland that most often arises from the parotid gland. A 51-year-old man developed a small mass on the right parotid gland 5 years ago. A preoperative magnetic resonance image showed abnormal intensity, an atypical characteristic for such a tumor; therefore, the diagnosis was difficult. Thus, a superficial parotidectomy was performed as a total excisional biopsy to remove the tumor. Histopathological analyses revealed that the tumor was composed of a single cyst comprising cells containing mucosal fluid, with proliferation of large cells...

BACKGROUND: Salivary gland secretory carcinoma is usually a low-grade neoplasm. However, high-grade transformation can occur and has important implications for clinical outcome. METHODS: A patient presented with an enlarging buccal mass. Magnetic resonance imaging (MRI) showed a tumor with a biphasic appearance along the right parotid duct. Local excision and histopathologic examination confirmed the diagnosis of secretory carcinoma with high-grade transformation...
