Immunopathological studies on rosacea.

Seven patients with papulo-pustular rosacea were investigated with immunofluorescence (IF) techniques. Indirect IF has been performed also with antibodies eluted from circulating lymphoid cells. Besides confirming the data in the literature on the positivity of the basal zone, anticollagen antibodies were found, and eluted antinuclear antibodies were detected against nuclei of cells in the epidermis and dermis, namely, scattered dermal, endothelial and eccrine duct cells.
