Fine-needle sampling of salivary gland lesions. VII. Cytology and histology correlation of five cases of epithelial-myoepithelial carcinoma.

Fine-needle sampling (FNS) of five cases of epithelial-myoepithelial carcinoma, three primary tumors, and two local recurrences, was performed preoperatively in five patients. Cytologic diagnoses of malignancy were established in all tumors (three were reported as adenoid cystic carcinoma, two as adenocarcinoma not otherwise specified). Material for cytologic evaluation was satisfactory in all cases. Adenoid cystic carcinoma, polymorphous low-grade adenocarcinoma, papillary cystadenocarcinoma and cellular type of pleomorphic adenoma are the main differential diagnoses.
