Perivascular mast cells in urticaria pigmentosa.

abstract：BACKGROUND:The cell origin of dermatofibroma (DF) has not been clarified satisfactorily. This study was undertaken to assess the distribution of fibroblasts and the relationship between fibroblasts and other constituent cells in DF by 47-kDa heat-shock protein (HSP47), a cell marker for skin fibroblast. METHODS:Immuno...
