Abstract

Since that first description of the so-called granular cell myoblastoma by Abrikossoff in 1926, it has been reported as occuring in many sites. This tumor is an unusual but not rare tumor. From the number of reviewed case reports(550) upto now, it appears that the occurence of multiple granular cell tumors (36) is much more common (7-16%) than traditionally believed. The precise histogenesis of this tumor is open to question. Most of this tumor is benign, but malignant ones have been reported. A case of malignant granular cell myoblastoma which was histologically proven and metastasized to the coracoid process of left scapula, the lung, and the skull, is presented with a brief of the literature.
