Abstract
Pleomorphic adenoma is the most common benign parotid gland tumor. Although its local recurrence rate is known to be high, the recurrence extending to the cervical region is rare. Here we report a case of a young female (25 years old) with pleomorphic adenoma of the parotid gland which showed multiple recurrences through facial to cervical regions over a span of eight years. We also discuss how this benign tumor with a high recurrence rate has been treated in other cases, and how it should be treated.
Highlights
The most common salivary gland neoplasm, pleomorphic adenoma, is most frequently found in the parotid gland in middle-aged women
Pleomorphic adenoma has a high rate of local recurrence (1% - 45%) [1]-[3] and the management of recurrent tumors is challenging because the probability of subsequent recurrence increases with each recurrent episode, making local control increasingly difficult and making damage to the facial nerves more likely [4]
We have experienced a rare case of recurrent pleomorphic adenoma that extends to the cervical region
Summary
The most common salivary gland neoplasm, pleomorphic adenoma, is most frequently found in the parotid gland in middle-aged women. It is known as a benign tumor with slow progression, and malignant transformation is rare. Pleomorphic adenoma has a high rate of local recurrence (1% - 45%) [1]-[3] and the management of recurrent tumors is challenging because the probability of subsequent recurrence increases with each recurrent episode, making local control increasingly difficult and making damage to the facial nerves more likely [4]. Tumor recurrence extending to the cervical region is reported to be rare in pleomorphic adenoma [4]. The operation, the management of the facial nerve, the role of postoperative radiotherapy, etc., are focused on
