Adenomyosis is a disease with a mysterious pathogenesis, defined by an abnormal displacement of the eutopic endometrium deeply and haphazardly inside the myometrium. Angiogenesis has been indicated to play an important role and our ann was to investigate whether vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1 alpha (HIF-1 alpha) expression and microvessel density (MVD) were different in women with and without adenomyosis. Immohistochemistry was performed in endometrial tissues in 23 patients who underwent radical hysterectomy for adenomyosis (14) and for ovarian cysts and fibroids (9) at an Academic Hospital. Compared to women without the disease, VEGF expression was increased in endometrium with a normal location in patients with adenomyosis. although not associated to a significant increase of HIF-1 alpha. and MVD. Moreover, the endometrium with an abnormal location in patients with adenomyosis showed an increased VEGF and HIF-1 alpha expression, particularly in the epithelial cells, associated to an increase of MVD, compared with the endometrium in a normal location in the same group of patients. Our present findings suggest that VEGF-mediated angiogenesis might be associated with the development of adenomyosis. In the ectopic foci the abnormal location might contribute to increased HIF-1a expression, stimulation of VEGF production, and increased vessel formation. In endometrium with a normal location, instead, where VEGF increased expression seems not to be correlated with HIF-1 alpha increased expression nor with ail increased MVD, other mechanisms might be reasonably Postulated. Additional studies arc required to explore new targeted and more effective treatment modalities.
