<B><I>Background</I>:</B> To observe cytological specimens of the salivary gland tumors, it is necessary to be familiar with histological findings. We describe cytologic findings of adenoid cystic carcinoma and compare them with histological findings.<BR><B><I>Histological and Cytological Findings</I>:</B> Adenoid cystic carcinoma is classified into 3 histological types-cribriform, solid, and tubular. The cribriform type is the most characteristic of this tumor, and cytologically shows metachromatic balls in cell clusters and in the background. There are 2 types of balls-mucous, composed of transparent stromal mucin, and hyaline, composed of light-green-positive, basement membrane-like materials. Differential diagnoses of the cribriform type are basal cell adenoma, basal cell adenocarcinoma, cellular pleomorphic adenoma, polymorphous low-grade adenocarcinoma, and epithelial myoepithelial carcinoma. The solid type shows large clusters composed of small atypical cells remuiniscent of a jigsaw puzzle. Differential diagnoses of the solid type are small cell carcinoma and basaloid squamous cell carcinoma. The tubular type shows glandular or trabecular clusters, and it may be difficult to distinguish it from polymorphous low-grade adenocarcinoma.<BR><B><I>Conclusion</I>:</B> It is well known that hyaline and mucinous balls are characteristic of adenoid cystic carcinoma, but they are not pathognomonic. Cytologically, we must distinguish adenoid cystic carcinoma from several salivary gland tumors.
