Abstract
- Granular cell tumors are rare disease can be which found in virtually any body site, including the tongue, skin, subcutaneous tissue, breast, rectum and vulva. However, they are rarely seen on the scalp. We report here on a rare case of granular cell tumor on the scalp. A 55-year-old woman presented with a non-tender, firm papule on the scalp. We removed the papule with excisional biopsy. Histopathologic examination showed well-circumscribed, non-capsulated nodule that consisted of large polygonal cells with abundant eosinophilic granular cytoplasms. The tumor cells were positive for S-100 protein staining. We diagnosed this case as granular cell tumor.
