Nonneural granular cell tumor treated with Mohs micrographic surgery

This is the authors' abstract. We don't add key points for this paper.

Nonneural granular cell tumor (NNGCT) is a rare neoplasm first described in 1991 by LeBoit et al.1 NNGCTs differ immunohistochemically from classic granular cell tumors (GCT), lacking expression of markers of neural differentiation (eg, S-100 and SOX-10). The histopathologic characteristics suggest nonneural differentiation; however, the precise lineage of NNGCT is currently not clear. Unlike GCT which is considered benign, NNGCT typically has benign behavior but can exhibit greater nuclear atypia and mitotic activity, with potential for lymph node metastasis.
