title: DNA flow cytometry of sebaceous cell carcinomas of the ocular adnexa: introduction to the technique in the evaluation of periocular tumors.
abstract: DNA content abnormalities are well recognized in tumor cell biology and kinetics. We introduce the technique of DNA flow cytometry through the study of the sebaceous cell carcinomas of the ocular adnexa. By correlating the data to the standard histopathologic parameters of pagetoid changes, degree of anaplasia, and stromal inflammation, significant associations are revealed. All aneuploid tumors demonstrate pagetoid spread, and more severe anaplasia and stromal inflammation. All diploid tumors are nonpagetoid and have lesser degrees of anaplasia and stromal inflammation. A complete review of the technique with a discussion of the implications and applicability to the study of ocular adnexal tumors is presented.
