ADENOMYOEPITHELIOMA OF THE BREAST IN A YOUNG WOMAN-A CASE REPORT-

Abstract

We report herein a rare case of an adenomyoepithelioma of the breast. A 21-year-old woman was admitted to our hospital for a painless lump in the upper outer area of the right breast. Ultrasonography of the breast demonstrated a 5-cm hypoechoic mass with a clear border and posterolateral shadow. The ratio of breadth to length of the tumor was 0.31. Ultrasound-guided fine-needle aspiration cytology showed class II. Wide excision of the tumor was performed. Histologically, the tumor was composed of proliferation of both epithelial and myoepithelial cell components. The mitotic index of the clear myoepithelial cells was low. Follow-up for fifty-six months has revealed no evidence of local recurrence or metastatic spread of the tumor. To our knowledge, this patient is the youngest one with this disease reported in the literature.
