Primitive non-neural granular cell tumor is a rare tumor of uncertain lineage that clinically presents as a solitary painless nodule most typically on the extremity or trunk of an adult. We report the case of a 20-year-old man with a small reddish papule on the abdomen, measuring about 2 x 3 mm, surrounded by a faint erythematous halo. Dermoscopy examination shows diffuse red color and weak whitish striae. However, only histological and immunohistochemical evaluation allowed us to perform the correct diagnosis.
