Abstract
Pleomorphic adenoma is the most common of all salivary gland tumors, constituting over 50% of all cases of tumors of both major and minor salivary gland origin and approximately 90% of all benign salivary gland tumors.
Of the major salivary glands, the parotid gland is the most common site of the pleomorphic adenoma. It may occur, however, in any of the major gland or in the widely distributed intraoral accessory salivary glands. The palatal glands are
frequently
the
site of origin of tumors, and other parts of origins are as follows ; upper and lower lip, buccal mucosa, tongue and occasionally other sites. The majority of the lesions are found in patients in the fourth to sixth decades, but they are also
relatively
common in young adults and have been rnown to occur in children. It is somewhat more frequent in women than men.
The term "mixed tumor" has masquaeraded under a great variety of names throughout the years (e. g., enclavoma, branchioma, endothelioma, enchondroma), but the term "p0leomorphic adenoma" suggested by Willis characterizes closely the unusual
histologic
pattern of the lesion. The accepted treatment for this tumor is surgical excision. The intraoral lesions can be treated somewhat more conservatively by extracapsular excision. In general, Lesions of the hard palate should be excised with the
overlying
mucosa, while those in lining mucosa, such as the lips, soft palate and buccal mucosa often can be treated successfully by enucleation or extracapsular excision. In our hospital, we experienced two patients who were identified pleomorphic adenoma
which
occurred at buccal mucosa, submandibular gland. The lesions were successfully treated by surgical excision.
