Introduction: Parotid glands contain adipose cells in the alveolar connective tissue and sebaceous glands that release lipid-secretary sebum [1]. The effect of parotid fat on parotid ADC measurement has been unavoidably neglected by the single-shot spin-echo echoplanar diffusion-weighted imaging (EP-DWI), which is essentially equipped by fat-saturation to eliminate chemical shift artifact. Unde...

Muscarinic receptors play an important role in secretory and vasodilator responses in rat salivary glands. Nitric oxide synthase (NOS) activity was found coupled to muscarinic receptor activation as well as to nitric oxide-mediated amylase secretion elicited by carbachol. Parotid glands presented a predominant M(3) and a minor muscarinic M(1) acetylcholine receptor population, though carbachol ...

epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. here a case of 58-year-old female presented with left cheek swelling of one-year duration. ct scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. histological examin...

Aplasia of the major salivary glands are very rare, and commonly occurs at the parotid gland. Patients are usually asymptomatic and diagnosed incidentally. But dry mouth, difficulty in swallowing, dental problems may be seen. Also mass complaints may occur due to compensatory hypertrophy of the other major salivary glands. Herein, we presented the magnetic resonance imaging findings of a very r...

Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the mi-nor 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 h...

Introduction: Pleomorphic adenomas are benign neoplasms of salivary glands. The simultaneous homolateral occurrence of these tumors in salivary glands is exceedingly rare.   Case Report: An adult female presenting to our OPD with the swelling of right-sided preauricular and submandibular regions was diagnosed with the pleomorphic adenoma based on fine needle aspiration c...

The occurrence of multiple distinct tumors in major salivary glands is quite rare. Although the most common tumor with bilateral synchronous or metachronous development is the Warthin's tumor, pleomorphic adenomas have been very rarely diagnosed simultaneously as well. The authors report two consecutive cases of patients with bilateral pleomorphic adenomas of the parotid glands discussing clini...

Sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have been reported thus far in addition to the two new cases of sialolipoma arising in the major salivary glands in this study. Thirty-six cases of sialolipoma published in English language reports were analyzed considering...

Prolonged isoproterenol treatment of rats is known to cause hypertrophy and hyperplasia of the parotid glands. Our results show that a dramatic increase in the synthesis or accumulation in the parotid glands of a series of proteins rich in proline also occurs with isoproterenol treatment. After 10 days of treatment (5 mg of isoproterenol/day) these proline-rich proteins (PRPs) comprise more tha...
