DLE lesions that develop very thick scale (hyperkeratosis) are called verrucous (wart like) lesions or hypertrophic (thickened) lesions. Mucosal discoid lupus is lesions affecting the mucous membranes in the mouth, nose and eyes. If lesions occur on the hands it is called Palmar DLE and Plantar DLE on the feet. Chilblain Lupus is also a variant of DLE.
Eleven criteria have been established for the diagnosis of SLE: Malar (over the cheeks of the face) “butterfly” rash, Discoid skin rash, Photosensitivity, Mucus membrane ulcers, Arthritis, Pleuritis/pericarditis, Kidney abnormalities, Brain irritation, Blood count abnormalities, Immunologic disorder (abnormal immune tests include anti-DNA or anti-Sm (Smith) antibodies, falsely positive blood test for syphilis, anticardiolipin antibodies, lupus anticoagulant, or positive LE prep test), Antinuclear antibody (positive ANA antibody testing).
