Two cases of adenolipoma of the breast.
Adenolipoma of the breast is a rare tumor. Two cases are described here and the literature is reviewed. Case 1 was a 52-year-old woman who had a 3-cm-long elastic hard tumor in the left breast. Case 2 was a 40-year-old woman who had a 3-cm-long elastic soft tumor in the left breast. In each case, mammography revealed well demarcated soft tissue density. Ultrasonography demonstrated well defined tumors composed of echogenic and sonolucent areas. These tumors were easily enucleated at surgery. Histologically, the tumors consisted of mammary ducts, fibrous stroma and adipose tissue, findings which are characteristic of mammary adenolipoma. An adenolipoma may still be misdiagnosed as a fibroadenoma or a fibrocystic disease. Characteristic findings of mammography and ultrasonography are emphasized.
