Abstract
Myoepithelioma is an uncommon benign tumor of the orofacial region arising from the salivary glands. These tumors are composed of specifically myoepithelial cells lacking ductal differentiation and were initially considered as a type of pleomorphic adenoma. Though they commonly arise from the parotid gland, there are a few cases that emerge from the minor salivary glands of the palate and oral cavity. Myoepitheliomas resemble many other tumors arising from the palate including pleomorphic adenoma. This report depicts a case of myoepithelioma of the minor salivary gland of the palate in a 23-year-old patient and the successful management of the lesion.

Abstract
Pleomorphic adenoma is a common benign salivary gland tumor which presents as a painless swelling that gradually increases in size, if left untreated. It is often seen involving the parotid gland. However, pleomorphic adenoma has been reported to involve the minor salivary glands as well. In this report, we present two cases of pleomorphic adenoma originating from minor salivary glands of the upper lip, occurring in two male patients of the same age (44 years) with markedly similar history of duration, size, and site of the lesion. The tumor was excised in both patients and sent for histopathological analysis which showed features of pleomorphic adenoma confirming the diagnosis.

In multinodular lesions or tumors with mixed benign and malignant components, malignant elements may be undetectable using fine-needle aspiration biopsy/cytology in preoperative pathological diagnosis of some cases, because of sampling error.

Abstract
Pleomorphic adenoma is the most common benign tumor affecting the major salivary glands and infrequently arises from the minor salivary glands. It involves the parotid of the major salivary glands and the palate of the minor salivary glands. This article presents a case of pleomorphic adenoma of the palatal minor salivary gland treated successfully by surgical excision.

Abstract
OBJECTIVES/HYPOTHESIS Information on polymorphous low-grade adenocarcinoma (PLGA) consists primarily of case reports and small institutional series with varying recurrence rates. In this report, we describe our institutional experience and conduct a review of the literature to assess the overall incidence of PLGA among oral salivary gland tumors and determine recurrence rates. STUDY DESIGN A retrospective case series and literature-based review was performed. METHODS Retrospective case series at an academic tertiary referral center. Review of clinical records and pathological analysis of tissue specimens from 20 patients treated for PLGA from July 1, 1990 to July 1, 2011. A literature-based review on PLGA was also performed. RESULTS Twenty patients (mean age, 54 years; eight males) with PLGA based on pathologic diagnosis were included. The most common initial presentation was an asymptomatic mass (45%), and the most frequent site was the palate (60%). Our literature review identified 54 case reports, eight case series, and 17 large series. In total, 456 cases of PLGA were identified, with an overall recurrence rate of 19%. Half of the recurrences occurred by 36 months; however, recurrences were reported up to 24 years after initial resection. CONCLUSIONS PLGA arises from minor salivary glands and is characteristically slow growing and indolent. Although these tumors may be histologically low-grade, our review highlights the high rates of recurrence of these tumors as well as the ability to metastasize to local lymph nodes and distant organs. The mainstay of treatment should be wide surgical excision with long-term oncologic follow-up. LEVEL OF EVIDENCE 4.

Abstract
Myoepithelioma is a rare form of salivary gland tumor composed entirely of myoepithelial cells. This tumor was formerly considered to be a subtype of pleomorphic adenoma; however, in the 1991 World Health Organization classification, it is listed as an independent entity. The most favorable site of occurrence of myoepithelioma is the parotid gland. Here, we report an extremely rare case of myoepithelioma of the upper lip. A 56-year-old woman presented with a painless mass on her upper lip. Magnetic resonance imaging revealed a 23 mm × 18 mm well-defined ovoid tumor. A benign minor salivary gland tumor was clinically suspected, and the patient underwent complete resection of the tumor under general anesthesia. The tumor was histopathologically diagnosed as a benign myoepithelioma of the minor salivary gland. Immunohistochemically, the tumor cells were positive for S-100 protein, AE1/AE3, CAM5.2, CK7, vimentin, and calponin, confirming the morphologic diagnosis of myoepithelioma. The patient's postoperative clinical course was uneventful, and satisfactory results were obtained both functionally and esthetically. To the best of our knowledge, this is the sixth case of myoepithelioma of the upper lip reported in English-language research.

Abstract
Salivary gland tumors are rare and account for 2-3% of tumors occurring in the head and neck. Pleomorphic adenoma is a benign neoplasm which is commonly encountered in the parotid gland and other major salivary glands. At times they can also develop in minor salivary glands of the palate. The majority of minor salivary gland tumors are malignant. This case report describes a case of mixed tumor in a minor salivary gland of the hard palate.

Abstract
Myoepitheliomas are benign neoplasms of salivary glands derived from myoepithelial cells. These tumors can occur at any age but are most common in young adults. This tumor is usually located in the parotid gland and the minor salivary glands of the soft palate and represents less than 1% of all salivary gland tumors. The myoepithelioma is classified in the follow cells types: spindle, plasmacytoid, reticular, epitheliod, and clear, additionally, mixed histological forms are described. The plasmacytoid myoepithelioma from palate salivary glands is considered as a rare entity. A 45-year-old lady presented with an asymptomatic, well-circumscribed, solid mass located on the hard palate, which was gradually increasing in size. A clinical impression of Pleomorphic Adenoma was made which on histopathological examination revealed cords, clusters, and sheets of homogenous, large cells with plasmacytoid characteristics and a prominent eosinophilic cytoplasm. Ductal and acinar differentiation were absent thus ruling out the pleomorphic adenoma, whereas, features consistent with plasmacytoid myoepithelioma were evident.

Abstract
Cystadenoma is a rare benign salivary gland tumor that chiefly originates in the minor salivary glands as a cystic growth with papillary projections into the cystic lumen without the lymphoid element. It is further classified into two histopathological variants that have been recognized by World Health Organization as the papillary and the mucinous forms of cystadenoma. Clinically, it is difficult to differentiate from other benign minor salivary tumors and mucous retention phenomenon. Diagnosis is chiefly based on characteristics histological features. It is believed that the salivary gland tumors are difficult to diagnose and interpret because there are varied patterns of presentation. The study of salivary gland disorders has increased in leaps and bounds. The authors report a case of mucinous cystadenoma of the minor salivary gland on the hard palate, which is even rarest of the rarely reported cystadenomas of the minor salivary glands.
