Metastasizing Pleomorphic Adenoma of Parotid Gland: A Case Report

doi:10.13701/j.cnki.kqyxyj.2026.07.014

Abstract

Abstract: Metastasizing pleomorphic adenoma (MPA), the rarest malignant subtype of pleomorphic adenoma, exhibits benign histology in both primary and metastatic lesions yet displays aggressive clinical behavior. Only 10 MPA cases have been reported in Chinese literature, none with lymph node metastasis. We present a case of parotid MPA with cervical lymph node metastasis and discuss its diagnostic and therapeutic implications.

Key words: pleomorphic adenoma, lymphatic metastasis, malignant pleomorphic adenoma
