Granular Cell Tumor in the Sartorius Muscle

Abstract

Granular cell tumor, a soft tissue neoplasm that originates in the nervous system, is a very unusual tumor. Granular cell tumor appears as a solitary painless lesion, which can arise at virtually any body site, but is mainly found on the skin, oral cavity, respiratory tract or digestive tract. However, an intramuscular granular cell tumor is very rare. We report on a case of a granular cell tumor in the sartorius muscle in a 71-year-old male patient along with a review of the literature.
