Background

Drug induced Lupus is a reaction resembling lupus that occurs after exposure to a drug. 

The time between drug exposure can range anywhere between 1 month and 10 years, often leading to difficulty identifying the offending agent.

Drug induced Lupus (DIL) is categorised into three subtypes:

• Drug induced systemic lupus erythematosus (DSLE)
• Drug induced subacute cutaneous lupus erythematosus (SCE)
• Drug induced chronic cutaneous lupus erythematosus (CCLE)

The focus of this chapter will be cutaneous manifestations of drug-induced lupus e.g. SCE, CCLE.
