Imaging features of granular cell tumor in the breast: Case report

Granular Cell Tumor of the Breast: Understanding the Cancer Mimic through a Series of Three Cases

Granular cell tumors of breast are rare neoplasms, majority of which are benign. Their imaging appearances are often indistinguishable from breast cancer. They may demonstrate a few differentiating features and unlike breast cancer, typically follow a benign course. Histopathology and immunochemistry form the cornerstone of diagnosis of granular cell tumor. In this article, we presented a series of three cases of granular cell tumors with variable presentations. Our goal is to increase familiarity for these neoplasms and for the readers to be able to distinguish them from the more common entity of breast cancer, as their prognosis and management differ.

Granular cell tumour of the breast: A case report

INTRODUCTION

Breast granular cell tumour (GCT) is a rare but usually benign lesion.

PRESENTATION OF CASE

We report a case of a woman with breast GCT.

CONCLUSION

Clinically and radiologically, GCT may mimic breast carcinoma. A conclusive diagnosis is made after a histopathological examination of the lesion. The treatment of choice is surgery.

Contrast-enhanced ultrasound of granular cell tumor in breast: A case report with review of the literature

Granular cell tumor is an infrequent, predominantly benign tumor originating from Schwann cells. Granular cell tumor of the breast (GCTB) can simulate breast malignant carcinoma on the clinical assessment. We herein present a rare case of GCTB which recurred in the contralateral breast. We believe the contrast-enhanced ultrasound (CEUS) findings of GCTB have never been described. The high similarity of breast malignant carcinoma makes its differential diagnosis difficult on the clinical and radiological features. In this report, we present the CEUS findings from a rare case of GCTB, explore the possible value of CEUS in differential diagnosis between benign breast lesions and malignant ones, and briefly review the literature.
