A woman presented with painful enlargement of her parotid and submandibular glands. She was shown to have the previously unreported combination of idiopathic thrombocytopenic purpura, Sjögren's syndrome, Hashimoto's disease, and myasthenia gravis. Parotid gland biopsy and bone marrow examination showed the presence of a rare lymphoplasmacytoid lymphoma. There was amyloid deposition in the parot...

myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary glands of the oral cavity. it is known to be a rare entity occurring at unusual locations, which makes it difficult to diagnose. such a rare case of myoepithelioma in salivary glands present at an unusual location around the left orbit is presented here.

The Warthin’s tumor or papillary cystadenoma lymphomatosum is a benign neoplasm which affects commonly the salivary glands und especially the parotid gland. We present a case of an 80-year-old Caucasian woman, who presented in our ENT department because of a progressive swelling in the left parotid gland. The clinical as well as the radiological findings suggested a multifocal lobular neoplasia...

Pleomorphic adenoma is the most common salivary gland tumor. also known as benign mixed Most commonly affected site parotid gland. It may occur in other major glands (submandibular and sublingual glands), lacrimal minor glands. arises a painless, firm swelling, slowly growing oral cavity. triphasic tumor that occurs epithelial, myoepithelial, chondromyxoid stroma. Complete surgical resection wi...

The present study was conducted to describe the histological features of parotid and submandibular salivary glands of European hamster. The glands samples were obtained from five adult males and microscopic slides were prepared using routine histological technique. The results showed that these glands divide in lobes associated with the ducts. The parotid was a typical serous gland, but the sub...

We sought to compare the diagnostic utility of magnetic resonance sialography (MRS) and digital subtraction sialography (DSS) in patients with suspected sialolithiasis or sialadenitis. Sixteen consecutive patients (4 female and 12 male, mean age 51+/-16 years) with suspected sialolithiasis or sialadenitis underwent DSS by a standard technique and MRS. MRS was obtained with a T2-weighted single-...

When [3H]inositol-prelabelled rat parotid-gland slices were stimulated with carbachol, noradrenaline or Substance P, the major inositol trisphosphate produced with prolonged exposure to agonists was, in each case, inositol 1,3,4-trisphosphate. Much lower amounts of radioactivity were present in the inositol 1,4,5-trisphosphate fraction separated by anion-exchange h.p.l.c. Analysis of the inosit...

Objective To evaluate the early changes in the apparent diffusion coefficient (ADC) of the salivary glands during radiotherapy (RT) and their association with the degree of xerostomia at 6 months after RT in patients with nasopharyngeal carcinoma (NPC). Materials and Methods We enrolled 26 patients with NPC who underwent RT. Each patient underwent diffusion-weighted MRI of the salivary glands...

introduction radiotherapy is regarded as the first treatment of choice for nasopharyngeal carcinoma. despite the advantages of radiotherapy, patients may suffer from a wide range of side-effects due to the presence of many sensitive normal tissues in these regions. if the absorbed dose exceeds the tolerance level in parotid glands and the spinal cord, myelopathy, lhermitte's sign and xeros...

Radiotherapy (RT) used for head and neck cancers causes permanent salivary gland dysfunction (SGD). Previous short-term studies have demonstrated that pre-RT salivary flow rates and the amount of radiation exposure to parotid glands influence the amount of RT-induced SGD. The purpose of this study was to determine which variables are related to the development of long-term post-RT SGD. Parotid ...
