Abstract

Schwannoma, also called neurilemmoma, neurinoma, a kind of a slow-growing benign neoplasm [1,2,3]. Schwannoma has a predilection for the head, neck, and extensor surfaces of the upper and lower extremities [4]. They can arise from Schwann cells of any nerve in any organ.

However, 2.6% of schwannnomas occur in the breast. Schwannoma is a clearly-bordered painful tumor and rare to arise within breast parenchyma. Fibroadenoma is a common benign breast tumor with also clearly bordered image. We experienced a case of schwannoma originated from the
pectral muscle nerve, and it was difficult to distinguish preoperatively from a fibroadenoma of breast.
