Abstract

Padmapriya Jaiprakash, Kanthilatha Pai

Granular cell tumor (GCT) is a rare neoplasm of the breast, accounting for <0.1% of breast tumors. GCT may mimic a malignant tumor clinically and radiologically, thereby causing overtreatment in a few cases. We present a case of a 28-year-old woman who presented with a breast lump of short duration, which was highly suggestive of malignancy radiologically. Wide local excision of the lump showed histological features suggestive of GCT, which was confirmed by immunohistochemical studies.
