Significance: Angiokeratoma corporis diffusum (ACD) is one type of angiokeratomas which are characterized on histology by superficial dilated capillaries with epidermal proliferation. ACD seriously influences patients' appearance and quality of life. Many therapies have been used to solved this problem. However, all the treatments have not been proved very effective. Hemoporfin-mediated photodynamic therapy (Hemoporfin-PDT) was considered recently as a promising treatment for PWS according to the principle of targeted photodynamic destruction of the vascular wall of the lesion.
Approach: APPROACH: A 27-year-old male patient diagnosed with angiokeratoma corporis diffusum (ACD) by skin tissue biopsy has undergone pulsed dye laser for times, but the result was unsatisfying. After evaluating and obtaining the patient's agreement, we utilized Hemoporfin-PDT with 530 nm LED green light to treat ACD. When followed up in the 1 year after 2 treatments, the patient was pleased with the efficacy that most red papules on his face disappeared.
Results: The patient achieved great improvement after two treatments.
Conclusions: Hemoporfin-PDT could be used to treat ACD.
