Can polymorphic light eruption treatment give you lupus?

PMLE: The exact cause of polymorphous light eruption isn't well understood. The rash appears in people who have developed a sensitivity to ultraviolet (uv) radiation from the sun or other sources, such as tanning beds or tanning lamps. This sensitivity results in sunlight-induced immune system activity that produces inflammation and a rash. No patients with pmle have progressed to lupus.
