An uncommon breast lump with the diagnosis of schwannoma

Introduction: Schwannoma (neurilemmoma) is a kind of a slow-growing, benign, and heterogeneous neoplasm originating from Schwann cells. Schwannoma has a predilection for the head, neck, and extremities. However, it can occur in the breast dermis, deep breast parenchyma, and axillary soft tissue. Case report: In this study, a 51-year-old woman is reported with a breast mass suspected of malignancy, who was diagnosed with schwannoma by a pathologist after surgery. In cases with palpable breast masses, Schwannoma should be considered as a part of differential diagnosis. In spite of various imaging modalities used in the diagnostics of breast lesions, excisional or core needle biopsy is suggested for the definitive diagnosis of schwannoma.
