What about subacute cutaneous lupus erythematosus?

The ring erythema type begins with edematous papules, gradually expands to the surrounding areas, and the skin lesions subside in the center. The peripheral areas are slightly infiltrated edematous erythema, with smooth surface or covered with a little scales, but no obvious hair follicle and corner plug. It is often in ring, multi shape or irregular shape. After healing, there is no scar, or temporary pigmentation, or persistent telangiectasia and depigmentation. The lesions were mainly distributed on the face, ears, upper chest back, shoulder and hand back.

Patients often have different degrees of systemic symptoms, such as joint pain, low fever, fatigue, myalgia and so on. Photosensitivity is also common. Generally, kidney and central nervous system are less damaged. The papule scale type starts as a small papule and gradually expands into a plaque with a little scale, which can be psoriasis like or pityriasis like.

The main rash type was discoid lupus erythematosus. In the early stage, it showed one or several flat papules or macular lesions, which gradually extended to the surrounding areas, forming a ring or irregular red plaque with micro protuberance, with adhesive scales on the surface, some with mild edema and obvious inflammation; In the later stage, the color of the plaque became dark, the center was slightly atrophic, the color became light, and adhesive keratinous scales could be seen at the atrophic area, which was not easy to peel off; After forced removal, the expanded hair follicle mouth can be seen at the base, and there are cutin plugs at the bottom of scales. Atrophic scars will be left after plaque healing. If it occurs at the hair site, it will cause permanent hair loss;

matters needing attention

Do not eat or eat less food with enhanced light sensitivity: such as fig, milk vetch, rape, yellow mud snail and celery, etc., should avoid sunlight after eating. Mushrooms such as mushrooms, Lentinus edodes, some food dyes and tobacco also have the potential effect of inducing systemic lupus erythematosus, so we should not eat them or eat them less.
