Adenomyosis is a benign pathology, common to both women at reproductive age as well as later during menopause. This condition is accompanied by a strong symptomatology, which has induced intense research on this topic. From a morphological point of view, it is represented by the existence of endometrial glands and, sometimes, of the periglandular stroma (endometriosis) in the structure of the myometrium, at a significant distance from the normal endometrium. Various inflammatory, vascular and mechanical factors accentuate the symptoms and evolution of this pathology. Our study included a total number of 32 patients, eight cases for each of the following histopathological subtypes: endometrium - proliferative phase, endometrium - secretory phase, myometrium with endometrial glands (adenomyosis), and myometrium with hyperplastic transformation of endometrial glands (hyperplastic adenomyosis), respectively. We have conducted clinical, morphological and morphopathological studies of the structures in question. Using the classical histological technique (Hematoxylin-Eosin), we identified the glandular structures; utilizing immunohistochemistry, we have labeled the endometrial epithelium with the anti-cytokeratin 7 (CK7) antibody and we analyzed the periglandular cell types of the immune system: T-lymphocytes using anti-cluster of differentiation (CD) 3 antibody, macrophages using anti-CD68 antibody, mast cells using anti-tryptase antibody, periglandular vascularization with the reaction using anti-CD34/anti-CD31 antibodies, thus demonstrating their involvement in the development of adenomyosis. The interesting aspect of this study is the technique of simultaneously labeling of the inflammatory, vascular and epithelial elements.
