*Neonatal lupus erythematosus, a rare disease affecting babies born to women with SLE, [[Sjögren's syndrome]], or sometimes no autoimmune disorder. It is theorized that maternal antibodies attack the fetus, causing skin rash; liver problems; low blood counts, which gradually fade; and heart block, leading to [[bradycardia]].<ref name="niams" />
*Childhood systemic lupus erythematosus, the pediatric variant of systemic lupus erythematosus.
*[[Drug-induced lupus erythematosus]], a drug-induced form of SLE; this type of lupus can occur equally in either gender.
*[[Lupus nephritis]], an inflammation of the [[kidney]]s caused by SLE
*Complement deficiency syndromes

Lupus may be classified into several subtypes according to clinical features which include: systemic lupus erythematosus, cutaneous lupus erythematosus, drug-induced lupus, and neonatal lupus. Systemic lupus erythematosus (SLE) itself may be classified into several subtypes based on glomerulonephritis and dermatologic manifestation. SLE may be classified according to dermatologic manifestations into 4 subtypes: acute cutaneous lupus erythematosus (ACLE), subacute cutaneous lupus erythematosus (SCLE), chronic cutaneous lupus erythematosus (CCLE), and intermittent cutaneous lupus erythematosus (ICLE). SLE may be classified according to glomerulonephritis into 6 subtypes: minimal mesangial lupus nephritis (class I), mesangial proliferative lupus nephritis (class II), focal lupus nephritis (class III), diffuse lupus nephritis (class IV), lupus membranous nephropathy (class V), and advanced sclerosing lupus nephritis (class VI).
Classification
Lupus may be classified into several subtypes according to clinical features which include:
Systemic lupus erythematosus (SLE)
Cutaneous lupus erythematosus (CLE)
Drug-induced lupus
Neonatal lupus
Based on this classification, SLE is a subtype of lupus that can be classified into different subclasses as well. CLE can be presented with or without systemic symptoms of the disease.
Systemic lupus erythematosus (SLE) may be classified into several subtypes based on glomerulonephritis and dermatologic manifestation.
SLE classification based on dermatologic manifestations
SLE may be classified according to dermatologic manifestations into 4 subtypes:[1][2][3]
