Abstract
Granular cell tumor (GCT) is a rare, benign neoplasm of Schwann cell origin. GCT is composed of cells with eosinophilic granular cytoplasm. GCT presents as a solitary painless nodule. Because of their subtle clinical presentation, GCTs are often misdiagnosed. This report of a 47-year-old woman with an auricular GCT serves to highlight that complete excision and histopathological evaluation should be attempted even in apparently benign cases, to ensure complete cure.
