5-aminolevulinic acid photodynamic therapy and excision surgery for nevoid basal cell carcinoma syndrome with multiple basal cell carcinomas and PTCH1 mutation.

Abstract This report describes a PTCH1 c.1804C > T (p.Arg602*) mutation causing a Chinese nevoid basal cell carcinoma syndrome (NBCCS) with multiple basal cell carcinoma (BCC) phenotype. Multiple modalities including microwave ablation, photodynamic therapy, and excision surgery have a good respond to the NBCCS. The current results broaden the spectrum of PTCH1 mutations responsible for NBCCS.
