Granular cell tumor, also known as Abrikossoff's tumor, is a rare benign tumor of neural origin, which can arise at any part of the body; however the tongue (30%) is the most commonly affected site. Its clinical behavior is usually benign although malignant and multifocal forms are also known to occur. CASE REPORT: A case of granular cell tumor in a 33 year old female who presented with a firm hyperpigmented nodule on the lateral aspect of the left upper arm. CONCLUSION: This case is quite rare: only a few cases were presented in literature with hyperpigmentation.
