The aim of this study was to evaluate adenomatoid tumours (AT) clinicopathologically in the female genital tract and compare the histomorphological features of ATs according to their uterine or tuba-ovarian location. Cases of AT were excised and collected from female genital tracts between the years of 2010–2017. Cases were evaluated depending on their clinical findings, localisation and pathological properties. There were 14 cases of AT. Ten cases were uterine, and 4 cases were adnexal tumours. The diagnostic ratio of uterine ATs was 64.3%, and of tuba-ovarian ATs was 21.4% (P > 0.05). The size of the largest tumour was 6 cm. Two of the uterine and one of the ovarian cases had a macrocyst; 2 uterine and one ovarian case had a microcyst; and 6 uterine had a combined microcystic/trabecular pattern. Uterine cases showed a higher number of smooth muscle component, signet-ring cells and infiltrative nature compared with other cases (P < 0.05). All uterine cases were infiltrative. Most of ATs of the female genital system were small in size and incidentally diagnosed in our cases but rarely detected as an adnexal mass forming lesion which mimics a malignancy. A comparative clinicopathologic analysis of these cases should be considered with the histomorphological and immunohistochemical features for an accurate differential diagnosis.
