A Case of Multiple Cutaneous Metastases from Metastasizing PleomorphicAdenoma of the Submandibular Gland / 대한피부과학회지

ABSTRACT

Pleomorphic adenomas are the most common neoplasms of the salivary glands. A long-lasting pleomorphic adenoma can develop into a malignant tumor. Malignant mixed tumor of the salivary gland includes carcinoma ex pleomorphic adenoma, carcinosarcoma, and metastasizing pleomorphic adenoma. The metastasizing pleomorphic adenoma is to be distinct from the true malignant mixed tumor, because it remains histologically benign and can metastasize. We report the case of a 64-year-old female with a long-standing goose egg-sized neck mass and multiple small firm nodules on the trunk and extremities, which showed histological features metastasizing pleomorphic adenoma of the salivary gland.
