A Case of Metastasizing Pleomorphic Adenoma Recurred as Cervical Lymph Node Metastasis after Parotidectomy / 대한이비인후과학회지

ABSTRACT

Metastasizing pleomorphic adenoma is a rare condition of metastasis from a histologically benign pleomorphic adenoma of the salivary glands. The bones and lungs are the most common metastatic locations for metastasizing pleomorphic adenoma, suggesting hematogenous spread of the primary tumor. However, we observed a case of metastasizing pleomorphic adenoma presenting with cervical lymph node metastasis, suggesting metastasis through the regional lymphatic system, in a 37-year-old woman who underwent parotidectomy 14 years earlier. Herein, we report this rare case and review the relevant literature.
