title: Analysis of number, size and distribution patterns of lipid vacuoles in benign and malignant mesothelial cells.
abstract: A quantitative analysis of the lipid vacuoles in benign hypertrophic and neoplastic mesothelial cells, using a size-independent distribution index, showed that computer-assisted image analysis for distribution patterns of cytoplasmic components can aid in distinguishing benign from malignant cells. Benign mesothelial cells had fewer lipid vacuoles, which were smaller and predominantly found around the nuclei. It is argued that, due to the high surface tension in the lipid vacuoles, the largest vacuoles are found in the center of the cells, which is the least flattened part of the air-dried mesothelial cells. It seems likely that the distribution pattern of rigid substructures, such as lipid vacuoles, varies between histologic and cytologic material as well as between cells processed by different cytologic methods with various cell-flattening artifacts. The study of the distribution of cytoplasmic components that differ in size was enhanced by using the defined size-independent distribution index, which incorporates the radius of the cell, the radius of the vacuoles and their respective centers of gravity.
