This case report highlights an unusual case where a foreign body in the parotid gland was initially thought to be sialolithiasis based on CT scans. The foreign body was safely retrieved from the parotid gland without formal superficial parotidectomy using methylene blue and an image intensifier to localize the lesion. Diagnosis and management of foreign bodies in the parotid gland are reviewed,...

Warthin's tumor is a benign salivary gland tumor of the parotid gland. Although bilateral or multicentric involvement of the parotid gland is common, extraparotid involvement is seen rarely. The nasopharynx is an unusual region for extraparotid involvement. In this article, we present a 52-year-old male case with a synchronized Warthin's tumor in the bilateral parotid gland and nasopharynx, and...

This is the first reported case of a marginal zone lymphoma with prominent lymphoepithelial sialadenitis of heterotopic salivary gland tissue. A 67-year-old female patient presented neck masses. Neck 3-dimensional computed tomography suggested Sjögren’s syndrome in both parotid glands and also revealed several cervical lymph nodes enlargement. Histologic findings of superficial parotid glands w...

We report a case of congenital fistula from ectopic accessory parotid gland to the cheek demonstrated by CT sialography and CT fistulography. The right parotid gland was abnormally located lateral to masseter muscle. The fistula was arising from an ectopic accessory parotid gland with ectopic duct positioned anterior to masseter muscle. CT sialography and CT fistulography were very helpful in t...

Objective(s): To review the findings of the patients with Sjögren’s syndrome (SS) having technetium-99m-pertechnetate (99mTc-pertechnetate) and gallium-67 citrate (Ga-67) salivary gland scintigraphy in the past eight years.Methods: The patients with SS, who were referred to our department for salivary gland scintigraphy during January 2008-December 2015 were studied using both 99mTc-pertechneta...

Oncocytomas are a group of rare neoplasms occurring in the parotid gland and account for less than 1% of all salivary gland tumors. Oncocytoma is a benign tumor composed of oncocytes with many hyperplastic mitochondria, usually presenting a solitary nodule. We reported a rare case of a slow-growing parotid oncocytoma in a 73-year-old woman who presented with a palpable mass in the left infra-au...

The molecular and pharmacological characteristics of muscarinic receptor subtypes in the rat parotid acinar cell line, PAR-C5, were determined and compared with native rat parotid glands to evaluate the PAR-C5 cell line as a model to study receptor-mediated secretion. Reverse transcription-polymerase chain reaction (RT-PCR) identified mRNAs for M(3), M(4), and M(5) receptor subtypes in both PAR...

extra-skeletal ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal ewing’s sarcoma. the usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. extra-skeletal ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. the cytological features of...

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 di...
