Answer

The lesion is uncommon. Exact figures are unavailable. Much of the literature on granular cell tumors consists of reports of single cases.

Granular cell tumors appear to be more common in black persons. Multiplicity of lesions is definitely more common in black persons. Up to 10% of granular cell tumors are multiple (ie, two to four lesions).
