Characterization of factor XIIIa+ dendritic cells in dermatofibroma: Immunohistochemical, electron and immunoelectron microscopical observations

The FXIIIa+ dendritic cells might be an essential cell of DF, and might have potential to develop HHF35+ fibroblastic or CD68+ histiocytic cells, under appropriate stimuli. The FXIIIa+ dendritic cells might be originated from DDC.
