A Rare De Novo Myoepithelial Carcinoma Ex Pleomorphic Adenoma in a Young Woman

Abstract EN

Carcinoma ex pleomorphic adenoma, an uncommon neoplasm of the parotid gland, accounts for less than 4% of salivary gland tumors.

It arises from a benign pleomorphic adenoma presenting in the sixth to eighth decades of life.

We present this as a unique account of a primary parotid gland carcinoma, arising from myoepithelial cells, without a known precursor lesion, in a 28-year-old woman.

This presentation seeks to provide familiarity of an unusual presentation of an unexpected rare pathology in a young female patient and the tools utilized for an accurate diagnosis.
