PLEOMORPHİC ADENOMA: REPORT OF THREE CASES

Pleomorphic adenomas are benign tumors of salivary glands that are derived from a mixture of ductal and myoepithelial cells. because of their remarkable histological diversity, these neoplasms have also been called mixed tumors. among all salivary gland tumors pleomorphic adenoma is the most common tumor. in this study we aimed to present clinical and histopathological features of 3 cases diagnosed as a pleomorphic adenoma. a 29-year-old female patient was referred to the inönü university faculty of dentistry maxillofacial surgery department with the chief complaint of a swelling in the left side of the hard palate. on physical examination, a mass was palpated and it was asymptomatic, slow-growing, non-ulsere submucosal nodule with diameter 4.0–3.0 cm. an incisional biopsy was performed and under local anesthesia the mass was dissected and removed.. after 1 year follow-up there was no evidence of recurrence a 61 year old female patient was referred to the inönü university faculty of dentistry maxillofacial surgery department with a history of a painless lump in her upper left labial sulcus. after incisonal biopsy pleomorfic adenoma was diagnosed. under local anesthesia the mass was dissected and removed. after 1 year follow-up there was no evidence of recurrence. case3: a 48-year-old male patient was referred to the inönü university faculty of dentistry maxillofacial surgery department for tooth extraction. on clinical examination a painless lump was detected in his hard palate. after in- cisonal biopsy pleomorfic adenoma was diagnosed. under general anesthesia the mass dissected and removed. af- ter 1 year follow-up there was no evidence of recurrence. the treatment of pleomorphic adenoma in minor salivary gland is wide local excision. enucleation alone is not advisable because of the high rate of recurrence. early diagnosis, treatment and long- term follow-up of pa are important because of the risk of malignant transformation and high risk of recurrence even several years after first excision.
