Granular cell tumor: importance of histopathology in determining malignant potential
Abstract
Granular cell tumors (GCTs), sometimes called Abrikossoff tumors, are rare and typically benign soft tissue tumors. Malignant GCTs, which are even rarer than benign GCTs, can occur and must be detected early given their high mortality rate. Distinguishing between benign and malignant GCTs is difficult clinically; however, histologic evaluation plays an essential role in this endeavor.
