Abstract
Fine-needle samplings of nine examples of primary neuroendocrine carcinoma of salivary glands were evaluated for their cytologic characteristics and were correlated with the corresponding histological sections. Consistent cytological findings were dispersed or loose clusters of poorly differentiated small- to intermediate-sized cells and occasional smudged nuclei. Mild to moderate nuclear pleomorphism, scant or absent cytoplasm, and nuclear molding were also observed. Rosette-like patterns and multinucleated cells were occasionally seen. Immunostaining of one recent case showed positivity for chromogranin and keratin. The differential diagnosis of primary and metastatic tumors with neuro endocrine features of the salivary glands is discussed.
