Abstract:
A 29-year-old man visited our department with an orange-colored patch on his right cheek. A skin biopsy confirmed the diagnosis of nevus sebaceous. As surgical excision was considered too destructive, photodynamic therapy (PDT) was proposed. Sixteen sessions of PDT was performed in total. There was a definitive but transient decrease in sebum production and destruction of the sebaceous glands. Overall, we were not able to achieve long-lasting clinical improvement after PDT.
