Diagnostic Considerations

Also consider the following:

  • Discoid lupus erythematosus - Demonstrates dyspigmentation, dilated follicles, and atrophy
  • Seborrheic keratosis - Greasy, brown crusts; sharply demarcated borders; nonerythematous base; may occur in nonexposed areas
  • Bowen disease - A larger plaque with a sharp outline
  • Invasive squamous cell and basal cell carcinomas - Indurated nodular lesions, more rapid growth, eroded or ulcerated surface [8, 9]
