Granular cell tumours (GCTs) are uncommon rare neoplasms that may occur in any part of the body. Approximately 5-8% of granular cell tumours occur within the breast. Although nearly always benign in behaviour, granular cell tumours of the breast can often mimic breast malignancies both clinically and on the basis of imaging techniques. This article reports five cases of benign granularcell tumours appearing in the breast, mimicking a malignant breast lesion. In addition to reporting the cases, the relevant literature was reviewed.
