Abstract:
In normal hurnan dermis, factor XIIIa positive dermal dendrocyte are located in the papillary areas closely associated with blood vessels and the upper reticular dem These cells represent a specific type of bone marrow derived dermal cells, distinct from Langerhans cells having some features in common with rnonocyte/macrophage lineage and with potential antier presenting activity. Although the significance of these cells has not yet been fully established, it been suggested that they play a major role in skin immune iesponses, in collagen synsthesis regultic and in wound repair. We report a case of acaqired fibrokeratoma which is studiec conventional histopathology and immunohistochemistry. Histopathologic findings of this case showed ovascular proliferation and the increased presence of fibroblast like cells as a common fe;ture of these benign tumors. Immunohistochemical staining with anti factor XIIIa antibody deiaoi strates increased numbera of positive dendritic cells in the upper dermis. There finding supports the fat that some fibroblagt like cells in the upper dermis of acquireid fibrokeratoma may be factor XIIIa positive dermal dendritic cells.
