Is there a relationship between adenomyosis and nabothian cyst?

Purpose: The aim of this study was to investigate whether there is a relationship between adenomyosis and nabothian cyst (NC) in a large patient series. Material and methods: The patient's data were scanned retrospectively and patients with a junctional zone thickness of 12 mm and above on magnetic resonance imaging were accepted as group adenomyosis (group A). Patients with a junctional zone thickness of less than 12 mm were not admitted as adenomyosis (control group). Both groups were compared for NC. Results: In group A, 176 (69.8%) patients had NC (n = 250), while in the control group (n = 202), 57 (28.2%) patients had NC. NC was significantly higher in group A than in the control group (p < 0.001). Conclusions: The aetiology of NC is still unclear. According to our results, similar factors may affect adenomyosis and NC aetiopathogenesis.
