  • 2. Clinical Case. Annular lesion on the breast.
    • A 60-years-old women.
    • The patient was referred to us for the assessment of a chronic radiodermatitis secondary to radiotherapy for breast carcinoma.
    • Physical examination
      • Slight Annular Lesion.
  • 3.  
  • 4.  
  • 5. Superficial basal cell carcinoma on chronic radiodermatitis.
    • THE KEY TO THE DIAGNOSIS
    Leaf-like areas Dermoscopy revealed many brown structures with a leaf-like configuration located at the periphery of the lesion. This was typical of leaf-like structures, also called maple leaf-like areas .

  • 9. Superficial basal cell carcinoma on chronic radiodermatitis.
    • Chronic radiodermatitis occurs with chronic exposure to doses of ionizing radiation over a prolonged period.
    • Producing varying degrees of damage to the skin and its underlying parts after a variable latent period of several months to several decades.
  • 10. Superficial basal cell carcinoma on chronic radiodermatitis.
    • Development of skin neoplasms is the most important complication of radiation therapy.
    • Squamous cell carcinomas are considered the most frequent tumors arising on chronic radiodermatitis areas.
    • Squamous and basal cell carcinomas may develop months to years after radiation exposure.
