BREAST NEURILEMMOMA

Neurilemmoma 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 breast neurilemmoma in a 27-year-old woman. The palpable mass was localized in the lower outer quadrant of the right breast. This intramammary tumor appeared ultrasonographically as a well-circumscribed, inhomogeneous solid mass. Microscopically, it had a pattern similar to that of neurilemmoma at other sites.
