  2. Atypical PEAR: This type is less common and can manifest as blisters, pustules, or other unusual skin reactions.

Causes of PEAR

  1. Radiation Exposure: PEAR occurs as a side effect of radiotherapy, which uses high-energy rays to target cancer cells. Sometimes, the surrounding healthy skin can be affected.
  2. Skin Sensitivity: Individuals with sensitive skin or a history of skin problems may be more prone to PEAR.
  3. Radiation Dose: The higher the radiation dose, the more likely PEAR may occur.
  4. Treatment Duration: Longer courses of radiotherapy may increase the risk of PEAR.
  5. Location of Treatment: PEAR is more likely to develop in areas of the body that receive radiation treatment.
  6. Individual Factors: Your genetic makeup and overall health can play a role in your susceptibility to PEAR.

Symptoms of PEAR

  1. Skin Rash: The most common symptom is a rash that can appear as red, pink, or even purple patches.
  2. Itching: The affected skin often becomes itchy and uncomfortable.
  3. Blisters: In atypical cases, fluid-filled blisters may develop on the skin.
  4. Swelling: Some individuals may experience swelling in the radiation-treated area.
  5. Pain: The skin may become painful, tender, or sore.
  6. Peeling: Skin may peel, resembling a sunburn.
  7. Scabbing: In severe cases, scabs may form on the affected skin.
  8. Changes in Skin Color: Skin color may change in the affected area.
  9. Dryness: The skin may become excessively dry and flaky.
  10. Fever: Rarely, fever may occur if the condition becomes severe.

Diagnostic Tests for PEAR

  1. Clinical Examination: A healthcare provider will visually inspect the affected skin to diagnose PEAR.
  2. Patient History: Information about your medical history and radiation treatment will help with diagnosis.
  3. Biopsy: In some cases, a small sample of the affected skin may be taken for further analysis.
  4. Blood Tests: Blood tests may be done to rule out other potential causes of skin problems.

Treatments for PEAR

  1. Topical Creams: Applying moisturizing creams or ointments can help alleviate dryness and itchiness.
  2. Corticosteroids: These anti-inflammatory medications can reduce swelling, itching, and redness.
  3. Antihistamines: These drugs can be taken to relieve itching and discomfort.
  4. Pain Relief Medications: Over-the-counter pain relievers like ibuprofen may help with pain and discomfort.
  5. Cool Compresses: Applying a cool, damp cloth to the affected area can provide relief.
  6. Avoid Irritants: Avoid using harsh soaps or perfumed lotions on the affected skin.
  7. Rest: Resting and avoiding friction on the affected area can help prevent further irritation.
  8. Wound Care: For more severe cases, proper wound care may be necessary to prevent infection.

Drugs Used in PEAR Treatment

  1. Hydrocortisone Cream: A mild steroid cream that reduces inflammation and itching.
  2. Prednisone: A stronger steroid medication that may be prescribed in severe cases.
  3. Antihistamines (e.g., Benadryl): These can help with itching and allergic reactions.
  4. Pain Relievers (e.g., ibuprofen): Over-the-counter pain medication to manage discomfort.
  5. Antibiotics: If there is a risk of infection, antibiotics may be prescribed.
  6. Emollients (e.g., Aquaphor): Moisturizing creams to keep the skin hydrated.
