Introduction: For the first time, Abrikossof described granular cell tumor in 1926. It was firstly believed that this tumor originated from skeletal muscle but using electron microsc...
Background and purpose: Mast cells as the multi-functional and complex cells play a key role in tumor progression. Due to the higher malignant potential of Oral Squamous cell carcinoma (OSCC) compared with cutaneous squamous cell carcinoma (cSCC), the purpose of this study was to compare the mast cells count in squamous cell carcinoma of the skin and oral cavity and evaluate their correlation w...
