A Case of Carcinoma ex Pleomorphic Adenoma of Hard Palate / 대한이비인후과학회지

ABSTRACT

Carcinoma ex pleomorphic adenoma is a rare neoplasm of the salivary gland. It has been reported that the most frequently affected site is the parotid gland, while the incidence rates in palatal minor salivary gland are much lower. Misdiagnosis is common, because the residual mixed tumor component may be small, and various carcinoma subtypes are possible. Clinical manifestations are mostly asymptomatic and have space occupying lesion sometimes. The recommended treatment is surgical excision with wide margins and subsequent radiation therapy. The author recently experienced a carcinoma ex pleomorphic adenoma of hard palate in a 62-year-old female with palatal mass. We treated with total excision with wide margins and there was no recurrence during the follow-up period of 2 years until now. We report this case with review of the literature.
