✦ Synopsis

Fine-needle sampling (FNS) of 412pleomorphic

adenomas, corresponding to 378 primary tumors and 34 local recurrences, was performed preoperatively in 3 78 patients. Concordant cytologic diagnoses were established in 376 tumors (91.3 %), whereas seven ( I . 7%) were only classified as benign. Sixteen (3.9%) tumors were considered to be suspicious and two (0.5%) were diagnosed as adenoid cystic carcinomas. InsufJicient material for cytologic evaluation was found in I 1 (2.6%) tumors. Pleomorphic adenomas were retrospectively classified according to the predominant histological differentiation: chondromyxoid, cellular, myoepithelial. or metaplastic. FNS performances were higher in chondromyxoid than in other types, with 95.2% concordant and 1.4% suspicious/ false-positive, vs. 81.8% concordant, and 11.5% suspicious/falsepositive cytodiagnoses, respectively.

We report a case of salivary duct carcinoma arising from a pleomorphic adenoma (ex pleomorphic adenoma) in a parotid salivary gland of a 70-yr-old man. Fine-needle aspiration biopsy showed two distinct subsets of cells. There was the typical biphasic pattern of pleomorphic adenoma consisting of blan
