A Rare Case of “Benign” Pleomorphic Adenoma with Cutaneous Metastases

摘要

Pleomorphic adenoma is a common neoplasm of the salivary glands that can, rarely, metastasize while retaining benign features. This usually occurs after multiple local recurrences after resection, possibly secondary to hematogenous and/or lymphatic seeding. The most common sites of metastasis are bone, lung, and cervical lymph nodes. Our patient had a rare case of metastasizing pleomorphic adenoma with cutaneous manifestations, without evidence of solid organ involvement.
