Unusual metastasizing pleomorphic adenoma of the parotid gland involving locoregional lymph nodes

Abstract

Carcinoma ex-pleomorphic adenoma (PA) is a complex group of malignant neoplasms arising in PA.
When microscopic features of the neoplastic cells are representative of carcinoma, the pathologist
can easily make a definite diagnosis, but when worrisome morphology is replaced by metastatic
behavior, the metastasizing PA (MPA) is a diagnostic challenge for the pathologist. Here, we present
an unusual MPA to cervical lymph nodes and discuss diagnostic challenges

Key Words: Cancer of parotid, dissection, lymph node, lymphatic metastasis, mixed salivary gland tumor
