Abstract
BACKGROUND Pleomorphic adenoma (PA) is the most frequent benign salivary gland tumor, but a lip PA is rare. Although this tumor may be definitively diagnosed by imaging or a tissue biopsy if it is reasonably large, PAs on the lip are relatively small, and they present findings that are similar to those of other lip lesions, which can make a preoperative diagnosis difficult. METHODS We analyzed all PAs in the oral region and lesions on the lips treated in our department over the past 20 years, and we discuss them together with the relevant literature. RESULTS We found that 11.8% (n=6) of the PAs occurred on a lip (upper lip: 9.8%, lower lip: 2.0%), and ~1% of all mass lesions of the lips were PAs. The average size of the lip PAs was 1.5±0.7 cm (range, 0.7-2.2 cm). For preoperative diagnostic assistance, ultrasonography (US) (n=4), magnetic resonance (MR) (n=3), or no imaging (n=2) was used. An excisional biopsy was performed in all cases, and to date, no recurrence or malignant transformation has been observed. CONCLUSIONS Lip PA is relatively rare. Because almost all of these lesions are small, a preoperative diagnosis is more difficult compared to palatal lesions. This tumor is also prone to long-term neglect and has the potential for recurrence and malignant transformation. It is thus necessary to perform an excision that includes the capsule and surrounding tissues, and careful postoperative follow-up should be continued.

Abstract
Pleomorphic adenoma (PA), also called mixed tumor, is the most common benign tumor of the salivary glands that mostly occurs in the parotid or submandibular glands but may also occur in the minor salivary glands that are distributed throughout the oral cavity. The common sites of PA of the minor salivary glands are the palates followed by lips and cheeks. Surgical removal with adequate margins is the principal treatment. We present a case of PA (arising from the minor salivary gland of the upper lip) - a rare site in a 65-year-old female who presented with a swelling upper lip of 2-year duration. Fine-needle aspiration cytology of the swelling revealed PA which was confirmed by histopathological examination after complete excision of the swelling.

Abstract
Introduction: Tumors of salivary glands are very rare in children overall, and rarely in minor salivary glands. Among them pleoomorphic adenoma (PA) is the most common benign tumor of salivary glands in children and it acounts 60% of all salivary neoplasms, frequently found in major salivary glands (85 %) and rarely in minor salivary glands (10-15%). PA appears as painless oval mass, elastic consistency and smooth surface. It characterized by slow evolution of growing. The diagnosis can be confirmed only by histopathological features, after total excision of the lesion. Case report: This case report present the uncommon case of the formation well circumscribed in upper lip region, nearby the frenulum labii oris superior in 10 years old school girl. After clinical intraoral examination of the formation approximately 2cm in size the surgical treatment has been done and histopathologic analysis resulted as PA. Conclusion: Long term follow-up examination is necessary due to possible recurence or malignancy alteration.

Abstract
INTRODUCTION Tumors of the parotid gland in children are rare and very little data has been published regarding the incidence of these tumors. We present a nationwide survey on this topic. METHODS Data regarding benign and malignant tumors in the parotid gland in children from January 1st, 1990 to December 31st, 2005 in Denmark was collected retrospectively from nationwide registries. This generated 61 patients for inclusion in this study. RESULTS 85% of the tumors were benign and the malignant tumors made up the last 15%. The most common of the malignant tumors was the acinic cell carcinoma (n=4) followed by the mucoepidermoid carcinoma (n=3) and adenoid cystic carcinoma (n=2). The overall female-to-male ratio was 1.18, with a ratio of 1.08 and 2.0 in the benign and malignant groups, respectively. At the end of follow-up (August 1st, 2014) two patients had died, one with adenoid cystic carcinoma and one with mucoepidermoid carcinoma. Both patients had perineural invasion and involved resection margins at presentation. The incidence was 0.12 and 0.53 per 100,000 children of the malignant and benign tumors, respectively. CONCLUSION Pleomorphic adenomas were the predominant neoplasm in the parotid gland in children. The most frequent of the malignant tumors was the acinic cell carcinoma, which is in contrast to previous studies. The proportion of malignant-to-benign parotid gland tumors is in contrast to earlier study reports not higher in children than in adults.

Abstract
The pleomorphic adenoma (PA) or mixed tumor is the most common neoplasm of the salivary glands, usually presenting with a non-specific clinical manifestation and a diverse histopathological pattern. The region of the lips is the second most common site for minor gland neoplasms. The aim of this paper is to report the case of a 39 year old caucasian woman presenting with a swelling on the right side of the upper lip combined with a history of trauma in the region of the upper right central incisor, eight years ago. The swelling was attributed to the periapical lesion of the upper right central incisor that was observed on the orthopantomography. Intraoperatively the surgeon came upon a nodule of firm consistency in the mucolabial fold. The histopathologic diagnosis of this lesion was benign mixed tumor of salivary gland. This report discusses the deviation in frequency of mixed salivary gland tumor between upper and lower lip, the clinical differential diagnosis, the histopathological pattern and the appropriate treatment.

Abstract
This case report describes a rare and unusual lesion found in a 33-year-old male, which was diagnosed as pleomorphic adenoma of the minor salivary glands in the upper lip. The tumor was a circumscribed, large firm mass, about 3 cm in diameter, almost obstructing the nares and characterized by slow growth. Complete excision was performed and the histopathologic analysis showed pleomorphic adenoma. The tumor did not recur. A brief review of the relevant literature is also presented.

Abstract
Pleomorphic adenoma is the benign tumor of salivary glands, which originates from the myoepithelial cells and intercalated duct cells. This tumor is more common in major salivary glands. This case report describes a rare and unusual lesion in a 55-year-old female, which was diagnosed as pleomorphic adenoma of the minor salivary glands in the upper lip. The tumor was a circumscribed, submucosal nodule, about 2.0 cm in diameter and was characterized by slow growth and rubbery consistency. Complete excision was performed and the histopathological analysis showed an epithelial salivary gland tumor with islands of plasmacytoid cells, duct like structures, in a variable stroma with chondroid, fibrous and myxoid appearance. No recurrence was observed 1 year after the surgery.
