We report two cases of granular cell tumors (GCTs) arising on rare sites, namely, the nape and umbilicus. While GCTs have a very characteristic histology, their clinical signs and symptoms are non-specific. Therefore, it is extremely difficult to make a diagnosis of GCT on the basis of clinical findings only. The two cases reported here were clinically similar to hypertrophic scars and keloids, respectively. Skin surgeons should remember that GCTs are an important differential diagnosis from hypertrophic scars and keloids.
