Abstract
- Granular cell tumors were originally described in 1926 by Abrikossoff as myoblastic myomas. They usually occur as solitary tumors but can be multiple in about 10% of cases. They have a predilection for the head, neck and tongue, but also occur in many other organs. Authors experienced a 37 year-old male patient with a granular cell tumor which exhibited the distinctive histopathologic appearance on light microscopy and electromicroscopy Also, granular cells were S-100 protein, vimentin and CD68 immunoreactive, but desmin and GFAP showed negative immunostaining. This finding suggests a neural origin for grenular cell tumors.
