A granular cell tumor of the breast parenchyma is a rare tumor accounting for 5-6% of all granular cell carcinoma and are mostly benign in nature. The malignant granular cell tumour is rare tumor that comprise 1-2% of all granular cell tumors. This is a case of a 35-year woman who presented with a palpable mass in the right breast.

Summary

Introduction

Granular cell tumour [GCT] or Granular Cell Schwannoma of the breast is a rare benign tumour of the neural cells. A diagnosis of benign granular cell carcinoma was made. With a disease free interval of one year, she developed local recurrence and she underwent simple mastectomy with adjuvant radiation therapy. This is one such case where histologically confirmed to be benign, but the clinical behaviour of the tumour favoured malignant variety.
