Background: The adenomatoid tumors (AT) are rare. They are found mainly in the female reproductive system and especially in the uterus. There is not national reporting on these. Objective: To describe the his-tological and immunohistochemical features of uterine AT. Method: Descriptive study of 32 patients admitíed to the Pathology Department of Clinica Las Condes. The cases studied were collected between November 1999 and November 2008. Results: The diagnosis of AT was performed in 21 hysterectomies and 11 myomectomies. In 14 patients were diagnosed as nodular single lesions (43.8%) and in 18 cases associated with leiomyomas (56.2%), the average size of single lesions was 2.6 cm, significantly greaterthan those associated with leiomyomas. The predominant histologic type most often correspond to angiomatoid (81.3%), followed by adenoid patterns (9.4%), solid (6.3%) and mixed (3%), the cystic pattern was not observed. The immunohistochemical study of ST was positive in 100% for cytokeratin AE1/AE3, calrretinin, vimentin and D2-40. It was negative for CD31 and CEA. Only 6.3% (2 cases) were positive for cytokeratin 5/6. Conclusio-ns: The AT is a benign tumor of mesothelial origin. Usually the diagnosis is a finding. In the uterus they are generally mistaken with leiomyomas or it is in associated with them. Based on the foregoing the treatment of AT should be conservative, only with resection.
