[Mullerian adenosarcoma of the cervix: case report with conservative management]

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.

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.

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.
