Benign myoepithelioma of the salivary glands: a true entity?

abstract：AIMS:Due to its limited availability there has been very little research on the mesenchyme of the nail unit. Recently, we discovered specialized mesenchymal cells beneath the nail matrix and proposed to call them onychofibroblasts. The purpose of this study was to further delineate more precisely by histology and immun...
