Scwannoma is a slowly growing benign tumour that originates from Schwann cells of the nerve sheath. It is rarely detected in breast tissue and only 30 cases have been published in English literature until now. The tumour often localize single and remains asymptomatic for years before diagnosis. The tumour size ranges from 0.7 to 22 cm. Although the clinical and radiological features of the tumour reveals a mass of a benign nature, differential diagnosis should be made from well-circumscribed malign lesions of breast such as fibroadenoma and medullary carcinoma. Fine-needle aspiration or core biopsy may be helpful for differential diagnosis. However, an excisional biopsy will likely be required to make a differential diagnosis. Radical excision should be performed in treatment to prevent recurrence. Herein, we report a case of schwannoma localized in the breast that was detected, followed by excisional biopsy in a patient with a breast mass.
