A case of photosensitivity reaction after photodynamic therapy for biliary papillomatosis / 대한내과학회지

ABSTRACT

Photodynamic therapy has been widely used in the treatment of various cancerous diseases. However, photodynamic therapy with a photosensitizer can cause a photosensitivity reaction on the skin. We report a case of a 64-year-old woman diagnosed with photosensitivity reaction after photodynamic therapy using the photosensitizer, porfimer. She presented to the emergency room with a skin rash on her face, neck, and both upper and lower extremities nine days after the photodynamic therapy. She denied any outdoor activity during that period. After administration of systemic corticosteroid and anti-histamine, her skin lesions resolved completely within seven days.
