The human uterine cervix consists mainly of epithelium and stroma, including smooth muscle cells and fibrovascular tissues. Fat cells in the uterine cervix have been rarely reported, and the only previous research article has shown that intracervical adipocytes are unrelated to clinical factors. The aim of this study was to investigate the frequency of fat cells in the uterine cervix, as well as to evaluate the relationship between intracervical adipocytes and clinicopathologic factors. We retrospectively selected 405 cases in Japanese women who received cervical conization at our hospital between 2003 and 2017. Cervical conization was not performed during pregnancy or within 1 yr after childbirth. The prepared histologic specimens for pathologic diagnosis were available in all cases. Age, menopause status, body mass index, gravidity, and parity were selected clinical factors, which were obtained in 214 patients. The mean patient age was 42 yr (range, 22-80 yr). Intracervical white adipocytes were observed in 13% of patients (53/405), with no brown adipocytes detected. The existence of intracervical adipocytes was significantly correlated to older age (P<0.0001), postmenopause status (P<0.0001), and higher body mass index (P=0.0018). Intracervical adipocytes might undergo adipocytic metaplasia from cervical stromal cells in accordance with aging, postmenopause status, or weight gain. Our result also suggest that cervical malignancy involving fat cells does not necessarily imply parametrial invasion.
