title: Sonographic findings in solitary schwannoma of the breast.
abstract: Solitary schwannoma is a benign neoplasm of Schwann cell origin, most frequently occurring in the extremities and the trunk and head regions. The breast is a very unusual site for this tumor. We report a case of benign schwannoma of the breast in a 76-year-old woman. The palpable mass was localized in the lower outer quadrant of the right breast. This intramammary schwannoma appeared sonographically as a well-circumscribed, hypoechoic, slightly inhomogeneous solid mass. Microscopically, it had a pattern similar to that of schwannoma at other sites.
