parotid mass

Ozan Erol, Erdinç Aydın
BACKGROUND: Hemifacial spasm is a sudden, involuntary and synchronous spasm of the facial muscles. The most frequent cause of this condition is compression of the facial nerves due to vascular pathologies. The most commonly used method of treatment is Botulinum toxin injection. However, the gold standard treatment is surgical treatment. CASE REPORT: A 64-year-old male patient with hemifacial spasms, which had occurred due to a rare parotid mass that had been surgically treated, is presented in this case...

Intraparotid hemangioma of the children is a rare neoplasm, posing diagnostic dilemma to the diagnosticians as well as treating clinicians. A 2-month-old male infant presented with a diffuse swelling in the parotid region since birth that was gradually increasing in size. The ultrasonography (USG) report was suggestive of a right intraparotid mass of uncertain etiology; whereas magnetic resonance imaging (MRI) report inclined toward a mass associated with chronic inflammatory pathology. Fine-needle aspiration cytology (FNAC) suggested two differentials - a vascular neoplasm of the parotid gland and a spindle cell neoplasm with increased vascularity...

INTRODUCTION: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy in the literature on this subject. MATERIALS AND METHODS: A cross-sectional study was performed in patients who presented to Qaem Medical Center with parotid masses and who were candidates for parotidectomy between June 2013 and January 2015...

A 61-year-old woman was admitted to our hospital with an ulcerated palate mass and swelling of the right parotid gland. Incisional biopsy from the hard palate revealed an extranodal marginal zone B-cell lymphoma, also called mucosa-associated lymphoid tissue (MALT) lymphoma. Final diagnosis was MALT lymphoma of the parotid gland with concomitant involvement of an extremely seldom site of involvement: the hard palate. To our knowledge, this report illustrates the first case of MALT lymphoma of the hard palate and parotid gland without an underlying autoimmune disease...

Merkel cell carcinoma (MCC) is a rare cutaneous cancer of neuroendocrine cell origin that occurs frequently on the head and neck. With a high incidence of local recurrence and regional and distant metastasis, it carries a poor prognosis. We performed a retrospective study to determine the prognostic implications of parotid gland metastasis in MCC of the head and neck. Our study population was made up of 14 patients-13 men and 1 woman, aged 62 to 87 years (mean: 75.9)-who underwent a parotidectomy for the diagnosis of MCC over a period of 10 years and 9 months...

OBJECTIVE: Prior studies have relied on computed tomography (CT) to assess alterations in anatomy among patients undergoing radiation for head and neck cancer. We sought to determine the feasibility of using magnetic resonance imaging (MRI)-based image-guided radiotherapy to quantify these changes and to ascertain their potential dosimetric implications. METHODS: Six patients with head and neck cancer were treated with intensity-modulated radiotherapy (IMRT) on a novel tri-(60)Co teletherapy system equipped with a 0...

Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass...

BACKGROUND: The clinical picture of IgG4-related sclerosing disease (IgG4-RSD) may mimic lymphoma, and should be in the differential diagnosis of patients with this clinical picture. CASE SUMMARY: A 32-year-old female had recurrent swelling of both eyelids for more than 15 years. Examination revealed elastic, firm, swollen lacrimal glands about 2-3 cm in diameter that was not painful. Head and orbits magnetic resonance imaging (MRI) showed mass lesions over the bilateral lacrimal glands, submandibular glands, and left foramen of ovale...

CONCLUSION: At least two groups of parotid malignancies exist, including one whose parameters of dynamic MRI closely resemble those of pleomorphic adenomas. Also tumors with long time to peak enhancement after administration of a contrast agent (Tpeak) and low washout rate (WR) should be considered malignant, especially single masses with concomitant lymphadenopathy located within the deep parotid lobe. OBJECTIVE: To verify if malignant tumors of the parotid are homogeneous in terms of parameters of preoperative dynamic MRI: Tpeak and WR...

Acinic cell carcinoma (ACC) is commonly thought of as a low grade malignant salivary neoplasm, and possibly has the best prognosis of all salivary malignancies with a 10-year survival of almost 90%. High grade transformation (HGT) in these tumours is a relatively rare event but is increasingly being reported. HGT (formerly referred to as dedifferentiation) in acinic cell carcinoma has shown to drastically reduce the survival rates and its recognition is imperative as more aggressive clinical management is needed...

INTRODUCTION: Intraparotid neurofibromas of the facial nerve are extremely rare and mostly associated with neurofibromatosis type 1 (NF1). CASE REPORT: This is a case of a healthy 40-year-old man, which underwent surgery for a preoperatively diagnosed benign parotid gland lesion. After identification of the facial nerve main trunk, a single large mass (6 x 3 cm) incorporating the upper nerve division was observed. The nerve portion involved in the mass could not be dissected and was inevitably sacrificed with immediate neuroraphy of the upper division of the facial nerve with 6/0 prolene...

INTRODUCTION: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors. However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. CASE REPORT: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, as well as a review of the literature, which demonstrates that this is an extremely rare malignancy with no strict protocol for treatment...

BACKGROUND: Fine needle aspiration (FNA) of head and neck masses is a common technique for providing cytology specimens to guide patient management. Cell blocks made from these specimens can be beneficial. Policy at our institution was changed from production of cell blocks only when requested by the pathologist to routine production for all non-parotid gland head and neck FNAs. The program was evaluated in terms of its impact on diagnosis and specimen turnaround time (TAT). METHODS: A retrospective study was carried out using electronic records at our institution...

Giant cell-rich osteosarcoma is a rare histologic variant of conventional osteosarcoma that affects mainly the extremities. Extraskeletal giant cell-rich osteosarcoma is therefore exceedingly rare. Here, we report the first case of this uncommon tumor involving the parotid gland in a 62-year-old male who presented with initial right jaw swelling. Radiologic work-up revealed a 6.2 cm mass involving the right parotid gland. Fine-needle aspiration cytology showed numerous multinucleated giant cells in a background of dyshesive epithelioid cells and rare clusters of spindle stromal cells, suspicious for malignancy...

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor, accounting for up to 60% of all tumors of the salivary gland and 75-80% of all parotid tumors. It has a slow but progressive growth pattern and if untreated can become greatly enlarged in size. However, giant PA is uncommon. We report a case of giant parotid PA of more than 10 years duration in a 60-year-old male Nigerian. A 60-year-old male patient with 10-year history of painless, massive, and pedunculated swelling in the left side of lower face measuring 25 cm × 23 cm × 17 cm in dimension...

Although Warthin's tumor is one of the common tumors of the salivary glands, Warthin's tumors with a prominent component of nodular oncocytic hyperplasia reminiscent of oncocytoma are rare. Here we report such a tumor, measuring 3 cm in diameter, found in the parotid gland of an 81-year-old man. Histologically, approximately 70% of the mass was a component of nodular oncocytic proliferation, and the remaining portion was a component of conventional Warthin's tumor. We performed immunohistochemical analysis to explore what factors determined the morphogenesis of the two components in the single mass...

The impact of gastric resection on the submandibular salivary gland (SSG) state, using histological and histochemical methods of investigation in experiment, was studied up. A relative mass of a SSG after gastric resection conduction have had reduced, and the accompanying changes in stroma were revealed with the gland's secretion enhancement. Essential dystrophic changes in the SSG parenchyma and stroma after gastric resection conduction may cause a pronounced disorders of their function.
