Twelve pleomorphic adenomas of minor salivary gland origin were examined for the distribution of S-100 protein, detected using the peroxidase-antiperoxidase (PAP) method. Strong S-100 protein immunoreactivity was noted in areas containing plasmacytoid cells, stellate and spindle cells against a myxochondroid or hyalinous stroma, and solid epithelial areas. Tubular and duct-like structures showe...

Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is...

Introduction: Minor salivary gland tumors are relatively rare, but have a higher chance of malignancy than major salivary gland tumors. The palate appears to be the most commonly involved site. The most frequent benign tumor is the pleomorphic adenoma. Case report: We report a case of a pleomorphic adenoma, which occurred in the hard and soft palate of a 34-year-old female and presented as an a...

Pleomorphic adenoma is a benign salivary gland tumor that represents less than 5% of benign tumors in childhood. World literature suggests salivary gland tumors account for less than 3% of the head and neck tumors and benign Pleomorphic adenoma of minor salivary glands arising de novo is very rare. Here we report a case of Pleomorphic adenoma of minor salivary glands occurring on the palate of ...

Salivary duct carcinoma (SDC) is a high-grade adenocarcinoma arising from the ductal epithelium of salivary glands which rarely involves the minor salivary glands. The varied histological presentation in the minor salivary gland tumors makes them the most heterogeneous group of neoplasms, making the diagnosis a challenge. This report highlights the importance of immunohistochemical markers in t...

objective: the aim of the present study was to estimate crude and age-standardized incidence rates for oral and pharyngeal nonsquamous cell malignant tumors in kerman province over a period of 11 years. materials and methods: the data used in this retrospective population-based study were extracted from the records registered in all pathology centers of kerman province from 1991 to 2001. all co...

BACKGROUND This study is an analysis of the prevalence of polymorphous low grade adenocarcinoma (PLGA) in epidemiological surveys of salivary tumors published in the English language from 1992 to 2012. METHODS These surveys included studies from different researchers, countries and continents. The 57 surveys for which it was possible to calculate the percentage of PLGAs among all malignant mi...

Clear cell carcinoma of the base of the tongue is a rare minor salivary gland neoplasm, and to our knowledge, the MR imaging appearance of this entity has not been described. We present the MR imaging findings in such a case and review the differential diagnosis for tongue base masses in an adult.

Pleomorphic adenoma is the most common benign tumour of major salivary gland presenting as a painless mass gradually increasing in size, usually involving parotid gland. In minor gland, it more palate. lip rare tumour. Thus, we present case pleomorphic originating from upper 75 years old male patient. The tumor was completely excised and sent for histopathological examination which showed micro...

Sialolithiasis is a common disorder affecting an estimated 12 in 1000 people each year and it accounts for more than fifty percent of the salivary gland diseases [1]. Although it can be found in children, it more commonly affects adults in their third to sixth decades [2]. There is a male predominance in sialoliths with some authors quoting that over 80% of the salivary calculi occur in the sub...
