A 50-year-old male patient presented to our hospital with multiple plaques and maculopapular lesions on his face and trunk for more than 20 years. A skin biopsy revealed a number of discrete nests of basaloid cells in the dermis where the peripheral cells are arrayed like a palisade. Multiple odontogenic keratocysts and falx cerebri calcification were found. The diagnosis of NBCCS was made. We treated this patient with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) with red light activation, 5% imiquimod cream and surgical excision for the basal cell carcinomas. All the skin lesions on his face improved substantially after eight sessions of red-light ALA-PDT from clinical observation. Red-light ALA-PDT proved to be a good therapeutic method for NBCCS in this case.
