Transient cutaneous hypomelanosis after cryoanesthesia.

Area of Science:

• Dermatology
• Aesthetic Medicine

Background:

• Superficial skin abscesses require effective treatment.
• Cryoanesthesia is utilized for pain management during minor surgical procedures.

Purpose of the Study:

• To report a case of hypopigmentation following cryoanesthesia with tetrafluoroethane spray.
• To highlight potential risks associated with this technique in specific patient populations.

Main Methods:

• A young Black female patient underwent incision and drainage of a skin abscess.
• Tetrafluoroethane spray was used for cryoanesthesia prior to the procedure.

Main Results:

• Post-procedure, a hypopigmented area was observed at the site of cryoanesthesia.
• Complete repigmentation of the affected skin occurred within four months.
• No similar cases have been previously reported in medical literature.

Conclusions:

• Cryoanesthesia with tetrafluoroethane may lead to transient hypopigmentation, especially in individuals with darker skin tones.
• The technique should be employed with significant caution due to the risk of prolonged or permanent skin color alteration.
