متن کاملThe Immunohistochemical Patterns of the β-Catenin Expression in Pilomatricoma
Background: Pilomatricoma is a benign follicular tumor that is composed of basaloid cells, transitional cells and shadow cells. β-Catenin is a 92-kDa protein, and it plays important roles in cell-cell adhesion at the cell membrane and signal transduction in the nucleus. β-Catenin has recently been shown to play an important role in the formation of hair follicle-related tumors, including piloma...
