Abstract

Objective : Reportedly, fiber cells are one of the most important cytological findings for uterine cervical squamous cell carcinoma. The aim of this study was to clarify the significance of fiber cells in uterine cervical squamous lesions (precancerous lesions and carcinoma).<br>Study Design : We analyzed 40 cervical smears including 10 cases consisting of four tissue-types (severe dysplasia, carcinoma in situ [CIS], invasive squamous cell carcinoma [SCC] stageI, and SCC stageII). The numbers of fiber cells were counted and compared among the different tissue-types. The diameters of cells and nuclei of the fiber cells were measured and compared with the degree of invasion.<br>Results : Fiber cells were observed in all the cases. We found that the numbers, size, and length-to-breadth ratio of the fiber cells were correlated with the degree of invasion.<br>Conclusion : Our results showed that the analysis of fiber cells is useful for the diagnosis of uterine cervical squamous neoplasia.
