title: [Cytologic study of glandular tumors in maxillofacial regions-- diagnostic application of nuclear DNA content].
abstract: We studied whether the DNA contents may be useful in the differential diagnosis of glandular tumors in the maxillofacial regions. In 25 of these tumors, the DNA contents were measured by microspectrophotometry, using 4 normal salivary glands as controls. We found that: (1) DNA histgram patterns were useful in differential diagnosis only in special cases. (2) The criteria were based on our decision and these tumors were classified into 3 types (a) Benign, (b) Low-grade malignant, (c) High-grade malignant. Our classification seemed to offer an objective means for differentiating between Benign & Malignant tumors of these types.
