Muscle biopsy has been used for a long time for diagnosis of muscular, nerurogenic and systemic disorders with muscle involvement, because only very few of these disorders show sufficient specific clinical features for definite diagnosis. Since the presence of difficulties in the screening of numerous genes, muscle biopsy could be a time and cost effective procedure for solving the diagnostic problems. The aim of this article is to mention the importance of muscle tissue in the evaluation of primary and secondary muscle diseases, special consideration of how to biopsy, handling the specimen and performing the special staining, and the microscopic findings in order to have better interpretation results.
