Malignant Granular Cell Tumor of the Lower Extremity in an Adolescent Male.
Granular cell tumors (GCTs) are extremely rare soft tissue tumors, with only 2% of tumors being malignant. Malignant GCTs are more often seen in women between the ages 40 and 60. There has been no case reported of a malignant GCT in a pediatric patient. We present a case of a 14-year-old male who presented with a large mass in his left lower extremity. After being biopsied, the mass was diagnosed as a malignant GCT. The tumor was completely excised with wide margins and close follow-up with the patient continued.
