Myoepithelial lesions of the breast: imaging characteristics and diagnosis with large-core needle biopsy in two cases.
Two mammographically detected myoepithelial lesions (one each in women aged 77 and 73 years) were diagnosed at large-core needle biopsy, with the results confirmed by means of surgical excision. The imaging features were nonspecific. A key clue to the diagnosis at histologic examination was the presence of a well-defined capsule around the lesion; hence, sampling of the margins of the lesion is essential. Radiologists should be familiar with myoepithelial lesions in the differential diagnosis of fairly smoothly marginated solid masses.
