Abstract: A 72-year-old female presented with intranasal mass for more than 3 years. Physical examination showed a peanut-sized black papule in the left nasal cavity, with rupture and ill-defined boundaries. The tumor occupies about two-thirds of the nasal cavity. Pathological diagnosis was basal cell carcinoma. The tumor site of this patient was special, and the wound after enlargement resection was difficult to repair, which was easy to cause organ deformation and scar. We removed the depth of the lesion to the superficial dermis, then the photodynamic therapy after operation was given, once a week, a total of 3 times. Twenty-eight days after operation, the lesions were completely repaired without obvious scar, and there was no recurrence of the  lesion after one year follow-up.

Key words: basal cell carcinoma, surgery, photodynamic therapy
