Abstract: Six cases of lupus erythematosus profundus(LEp)were reported, Aftet reviewing, 60 cases of LEp in the literature the authors found 3 types of trans-formation in these 66 cases of LEp.They are; (1)remained unchanged for a long time(8/66),(2)intertransformable between DLE or SLE under certain conditions(46/66),(3)two or three.types of them could occur at the same time(12/66), Therefore we take this 3 types of LE as different manifestations of the disease, DLE and SLE are polar types and LEp is the intermediate type. If LEp appears first, it map transform into DLE of into SLE under certain conditions. Finally the authors put forward a suggestion on the spectrum of LE expressed diagrammatically.
