title: Schwannoma of the breast showing massive exophytic growth: a case report.
abstract: Schwannoma is a slow-growing tumor that frequently occurs in the extremities, the trunk and the head region. Its occurrence in the breast is rare with only a few cases being reported. We present here the case of breast schwannoma in a 41-year-old woman who presented with a palpable mass in her right breast. This is the first report of breast schwannoma that showed massive exophytic growth with invasion of the skin, and it was initially presumed to be a breast cancer on preoperative mammography, ultrasonography and breast MRI examinations. Complete excision of the mass was done and pathology revealed a plexiform schwannoma.
