Subacute cutaneous lupus erythematosus (SCLE ) is a clinically distinct subset of cases of

skin lesions that are scaly and evolve as poly-cyclic annular lesions or plaques similar to those of plaque psoriasis.[1]

Characteristically the lesions appear in sun-exposed areas such as the vee of the

Therapy generally involves sun avoidance and protection and topical

immunosuppressants such as methotrexate are also used.[3]

Lesions of SCLE may have an annular (shaped like a ring) configuration, with raised red borders and central clearing.[4][5]

Signs and symptoms

The lesions of systemic lupus erythematosus are characterized by their distribution, which can be either annular with central clearing or papulosquamous. The lesions normally heal without atrophy or scarring, and these two forms can happen at the same time. While telangiectasia or hypopigmentation may occur, most patients' skin returns to normal.[6] Serologic abnormalities, musculoskeletal complaints, and mild illness are common in patients with SCLE.[7] SCLE typically avoids the face and is more common in sun-exposed areas such as the neck, shoulders, chest, and extensor surfaces of the arms.[6]

Causes

The etiology of systemic lupus erythematosus is not well understood. Sunlight exposure is the traditional precipitating factor in patients with immune dysregulation and an aberrant milieu of genetic predisposition. There have also been reports of drug-induced SCLE. Angiotensin-converting enzyme inhibitors, anticonvulsants, beta-blockers, and immune modulators, such as TNF alpha inhibitors, are frequently used medications that have been linked to SCLE. Case reports of SCLE developing in cancers have been published.[6]
