Carcinoma ex Pleomorphic Adenoma: Multi-Institutional Retrospective Cohort Study. [PDF]

OTO Open
Abstract Objective Carcinoma ex pleomorphic adenoma (CXPA) is a rare malignancy and survival rates vary throughout literature. The primary objectives are to study overall survival (OS), disease‐specific survival (DSS), locoregional recurrence‐free survival (LRFS), and secondarily margin status.

Cystic Change in Pleomorphic Adenoma: A Rare Finding and a Diagnostic Dilemma [PDF]

Journal of Clinical and Diagnostic Research, 2015
Pleomorphic adenoma forms the majority of salivary gland neoplasms. Cystic change in pleomorphic adenomas is a diagnostic dilemma and can mimic mucoepidermoid carcinoma, mucocele or carcinoma ex pleomorphic adenoma and squamous cell carcinoma. Hereby we

Primary intrathyroidal adenocarcinoma ex pleomorphic adenoma: A case report

Otolaryngology Case Reports, 2021
Carcinoma ex pleomorphic adenoma (CXPA) is a rare and aggressive malignancy arising from a benign pleomorphic adenoma. We present what is, to the best of our knowledge, the first case of a primary intrathyroidal carcinoma ex pleomorphic adenoma in an ...

Mucoepidermoid carcinoma ex Pleomorphic adenoma [PDF]

Cancer, 1998
In contrast to most major salivary gland malignancies, mucoepidermoid carcinoma has been rarely documented and tentatively accepted as carcinoma ex pleomorphic adenoma. The authors present the cytologic and clinical findings for six examples of these rare tumors.The six examples were identified during an extensive review of the authors' salivary gland ...
