Abstract

INTRODUCTION: A benign tumour of Schwann cells of the peripheral nerve sheath is called Schwannoma, also called as neurilemoma or neurinoma. Most breast cancers and other breast tumors have an epithelial cell origin, with stromal and myoepithelial cell tumors being less common. A nerve sheath tumor arising from neural crest-derived Schwann cells within the breast is rarer still. For unknown reasons, these cells can sometimes grow in a neoplastic fashion which results in a benign tumor termed as schwannoma. Neurilemoma, neurinoma, peripheral nerve sheath tumor and schwannoma are considered to be synonymous though the term schwannoma appears to be more precise than the others as this tumour is believed to arise from schwan cells. Schwannoma are commonly slow growing solitary lesions which rarely show malignant transformation. The clinical significance of this benign tumor is that it may clinically and radiographically simulate malignant
