S100 negative granular cell tumor of the oral cavity: dermoscopy and surgical approach

We report the case of a 47-year-old male patient with S100 negative granular cell tumor of the oral cavity, focusing on dermoscopic features as well as surgical approach, not previously reported in the literature. The study contributes to the literature on dermoscopy and surgical treatment for this tumor and provides a practical approach to differentiating non-neural granular cell tumors and granular cell tumors.
