Clinical Study of the Exfoliative Cytology on Oral Mucosal Lesions in Kyushu Dental University Hospital

Abstract

The purpose of this retrospective study was to evaluate the exfoliative cytology of oral mucosal lesions. We researched 225 specimens of 211 patients who underwent exfoliative cytology at the Department of Oral Medicine in Kyushu Dental University Hospital from April 2018 to March 2019. Patient age, sex, location of lesion, clinical diagnosis, the results of exfoliative cytology, presence of candida and histopathological diagnosis were analyzed. In 20 out of 24 cases （83.3％） which showed positive or suspicious cytology, epithelial tumor including cancer was detected. However, four cases showed false-negative due to enhancement by inflammation and lower cellular atypism. This study suggested that exfoliative cytology might be useful for detecting oral epithelial tumors including cancer.
