Abstract

Two patients suffering by a granular cell myoblastoma are presented. Symptoms were present from some months and principally consisted of the presence of a painless mass. Local surgical excision was successful in two patients. The histogenesis of the tumor is still discussed although recently light and electron microscopic study and histochemical ρrocedures have been shown a Schwann cell origin.
