Xanthogranulomatous change in a pleomorphic adenoma: An extremely rare variant/degenerative change. Is it fine needle aspiration induced?
Sign Up to like & getrecommendations! Published in 2020 at "Diagnostic Cytopathology"
DOI: 10.1002/dc.24585
Abstract: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor characterized by morphological diversity, metaplastic changes, degeneration, cystic change, altered differentiation, and rarely malignant transformation, thereby may create a diagnostic dilemma on cytology. Xanthogranulomatous… read more here.
