Granular cell tumor presenting as an axillary mass: A case report

Abstract

Granular cell tumor (GCT) is a tumor that can arise at virtually any body site. About 5 to 15% of the cases occur in the breast, and it is relatively rare in the axilla. %1-2 of granular cell tumors are malignant. The clinical symptoms and imaging examinations of breast GCTs are non-specific and can easily be confused with malignant tumors. Most are benign and reportedly malignant cases are rare. We report a 59-year-old male with granular cell tumor in axillary region existed approximately 2 years. The palpable mass was around 15mm in diameter and felt clinically suspicious of malignancy. Tru-cut biopsy of the mass showed granular cell tumor features and surgical excision was performed. Early diagnosis and complete resection of the tumor remains the best treatment method.
