Acne-like eruptions induced by PUVA-treatment

Area of Science:

• Dermatology
• Photobiology

Background:

• Photochemotherapy, utilizing psoralen and long-wave ultraviolet light (PUVA), is a common dermatologic treatment.
• Known side effects include nausea, pruritus, and erythema.

Observation:

• Acneiform eruptions have been recently reported in patients undergoing PUVA therapy.
• This study observed dermatologic side effects in patients treated with 8-methoxy-psoralen and UVA irradiation.

Findings:

• Four out of 80 patients (5%) developed perioral dermatitis.
• Two of these patients also experienced acneiform eruptions on the forehead.

Implications:

• These findings highlight potential adverse dermatologic reactions to PUVA treatment.
• Clinicians should be aware of these side effects when prescribing photochemotherapy.
