INTRODUCTION: The presence of atypical endometrial cells in the Papanicolaou (Pap) test has been associated with an increased rate of endometrial malignancy, with reported rates ranging from 14% to 47%. However, most reported studies have focused on patients who were aged >40 years. The purpose of the present study was to investigate the clinical significance of identifying atypical endometrial cells in Pap test samples in women aged <40 years of age.
MATERIALS AND METHODS: A search of the cytology Pap test database was performed from 2000 to 2014 using the keywords "atypical endometrial cells" or "atypical glandular cells favor endometrial origin" in women aged <40 years. The available ThinPrep slides were reviewed. The patients' clinical presentation, follow-up endometrial biopsy findings, treatment, and clinical follow-up data were recorded. Endometrial carcinoma tissue sections were screened for Lynch syndrome.
RESULTS: The database search yielded 63 study cases. Of these 63 patients, 52 had subsequently undergone endometrial biopsy. Of the 52 patients with follow-up biopsy findings available, 9 (17.3%) had premalignant (5 with atypical hyperplasia) or malignant (4 with endometrioid adenocarcinoma) lesions. In addition, 16 patients (30.8%) had other endometrial pathologic features. The 9 patients with premalignant or malignant endometrial lesions (8 white, 1 black) were overweight or obese; 3 of the patients did not have any clinical symptoms. All 4 patients with endometrioid adenocarcinoma had negative Lynch syndrome screening findings.
CONCLUSIONS: Our results suggest that it is important to recognize the presence of atypical endometrial cells in the Pap tests from young patients, given its association with the finding of premalignant and malignant pathologic features in subsequent endometrial biopsies.
