Cellular schwannoma of the breast: A case report and review of literature

Schwannoma of breast is a relatively uncommon disease characterized by painless and slow growing. We report a case of a 28-year-old female who present a mass of the right breast. Ultrasonography revealed a well-circumscribed and inhomogeneous hypoechoic mass under the skin of the breast. Then a biopsy and immunohistochemical analysis were performed. The results were suggestive for cellular schwannoma of breast. The tumour was removed successfully and the patient has been followed-up for six months with no evidence of recurrence. Cellular schwannoma is a rare benign neoplasm without metastasis. Distinction cellular schwannoma from other malignant tumours is very important. It is necessary to combine strict criteria on histological, immunohistochemical analysis, biological behavior, image examination and clinical features for the final diagnosis.
