Mullerian adenosarcoma of the cervix: case report with conservative management

Abstract

Background: Mullerian adenosarcoma is a rare gynecological malignancy with a low malignant potential, with biphasic growth, consisting of a benign epithelial element and a malignant mesenchymal element. It occurs in all ages predominating in postmenopausal women. Cervical localization of Mullerian adenosarcomas is rare; however, it is associated with a presentation in young women. The diagnosis is made by anatomopathological study of the lesion and immunohistochemistry. The prognosis is generally good although the recurrence rate is high. Clinical case: We present the case of a 27-year-old patient who attended a gynecological consultation with bleeding and transvaginal flow. During the gynecological examination, a polypoid lesion originating in the cervix was identified, which was removed by torsion and was diagnosed as Mullerian cervical adenosarcoma. Subsequently, a cervical cone was performed because the patient refused hysterectomy. Conclusions: Mullerian cervical adenosarcoma is a rare neoplasm with a recurrence rate that can reach up to 50% of cases, so close follow-up is necessary. A local excision can be considered in patients without poor prognosis factors and who wish to preserve their fertility.
