Granular cell tumors – pro
Granular cell tumor develops on any skin or mucosal surface, but occurs most commonly on the tongue( 40%). Other names for this rare caner are: Abrikossoff’s tumor, Granular cell myoblastoma, Granular cell nerve sheath tumor, and Granular cell schwannoma. It is now believed to be a neopalstic process. It is called granular because of the accumulation of secondary lysosomes in the cytoplasm. The literature is based on case reports and series and presents the impression that radiation and chemotherapy are not needed for benign lesions and are not effective for malignant lesions.
