Multiple cutaneous granular cell tumors in childhood.
We have described two children with multiple cutaneous granular cell tumors (GCT) and have reviewed the literature. Multiple tumors of the skin are relatively rare, especially in children, with only 18 pediatric cases previously reported. Surgical excision of rapidly growing or symptomatic lesions is the treatment of choice. In these two children with multiple GCT, three lesions were excised. Specific stains for enolase and S-100 protein clearly demarcated tumor margins after surgical excision. Despite intensive investigation, the histogenesis of this tumor is still in dispute. The most tenable theory at this time is that these tumors are derived either directly from Schwann cells or from undifferentiated cells developing neural characteristics.
