RARELY SEEN BREAST NEOPLASM: ADENOMYOEPITHELIOMA

Abstract

Breast adenomyoepithelioma which is a rare tumor of the breast is characterised by biphasic proliferation of epithelial and myoepithelial cells of breast. It’s hard to diff erentiate adenomyoepitheliomas from other neoplasms by radiological evaluation. Although generally having benign characteristics, adenomyoepitheliomas are rarely gaining malign transformation and making distant metastasis. Here, we present a 16-year old girl with a lump in her right breast. The lesion thought to be fi broadenoma in pyhsical examination, but by ultrasonographic examination it was found that there is a 3*2 cm solid lesion containing 4mm cyst. This is the youngest case with adenomyoepithelioma in the literature. Because of the diffi culties in pathological diagnosis and having risks of local and distant metastasis, wide excision of these lesions are recommended in the treatment.
