Hyperperistalsis induced by the local production of estrogen would constitute a mechanical trauma and generate an increase in desquamation of fragments of the basal endometrium. An interesting Chinese study (2) showed that the RhoA/ROCK expression in the junctional zone of women with adenomyosis was significantly higher than in controls. Additionally, the same study demonstrated that estrogen-mediated contractions in the adenomyosis group of patients were significantly higher than controls, suggesting that estrogen may affect uterine junctional zone contractions in adenomyosis by enhancing the RhoA/ROCK-I signaling pathway. The importance of imaging techniques to distinguish between different types of adenomyosis (3) was also expounded. Diffuse or focal adenomyosis may present different features and symptoms, and they may have different impacts on fertility. Regarding this point, a proposal of adenomyosis classification using imaging was presented (4) identifying four different forms of the condition (diffuse, nodular, sclerotic and cystic). A correct assessment of the type of adenomyosis could help clinicians to better identify which patients would benefit from medical treatment, hysterectomy or conservative uterine-sparing surgery. Oral communications concerning the relationship between adenomyosis and endometriosis, especially with deep infiltrating endometriosis (DIE) were presented. Recent research demonstrates that the presence of focal posterior
