Granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. Occurrence in limbs is even rarer. These tumors account for approximately 0.5% of all soft tissue tumors. Granular cell tumor can also affect other organs including skin, breast, and lungs. Local recurrence and metastasis is potentially higher in malignant forms with poor prognosis in respect to the benign counterparts. The average diameter of the tumor is usually about 2-3 cm. We report a granular cell tumor in the leg with an unusual size.
