Granular cell tumor of the breast: a report of the three cases

Granular cell tumors (GCT) of the breast are uncommon benign neoplasms that are usually indistinguishable from breast cancer with respect to their clinical and radiological presentation. FNAB can be a usefull diagnostic tool, but histological examination is essential for the correct diagnosis. This benign tumor should be considered among the diagnostic possibilities in the presence of a lesion with mammographic and ultrasonographic indications of highly probable malignancy. We present three cases of breast GCT that mimicked primary breast cancer. Benign neoplasm was diagnosed and local excision was carried out rather than mastectomy and lymphadenectomy. (Author) 9 refs
