Discoid lupus erythematosus - A Brief Discussion



Discoid lupus erythematosus is a benign disorder generally seen in younger females. It very rarely progresses to systemic lupus erythematosus (in less than 5% of cases).

Discoid lupus erythematosus is characterized by follicular keratin plugs and is thought to be autoimmune in etiology.

Clinical Features

  • erythematous, raised rash, sometimes scaly
  • may be photosensitive
  • more common on face, neck, ears and scalp
  • lesions heal with atrophy, scarring (may cause scarring alopecia), and
  • pigmentation

Management


  • topical steroid cream
  • oral antimalarials may be used as second line e.g. hydroxychloroquine
  • avoid sun exposure
