Polymorphous low-grade adenocarcinoma--management and reconstruction with temporalis myofacial flap.

Polymorphous low-grade adenocarcinoma is a rare, malignant salivary gland tumor, which is found almost exclusively in minor salivary glands. It is more frequent in the third-seventh decade of life, with a clear female predilection in a 2:1 ratio. It is usually located in the hard or soft palate, although it may be found in the rest of the oral cavity too. It is rare in major salivary glands. In general it has good prognosis, with recurrence rates in the range of 17-24%. Although rare, metastasis to regional lymph nodes has been reported. We report a case of 38 year old female patient who reported with recurrent low grade polymorphous adenocarcinoma in the hard palate, who has been treated with wide excision of the lesion, with reconstruction of the defect using temporalis myofacial flap.
