Abstract

Some basal cell carcinomas (BCCs) are indistinguishable from nevi based on clinical manifestations. Therefore, it is often difficult for the excision margins of the initial surgical treatment to achieve radical removal of the malignancy. This study was a comparative analysis of the clinical results of aminolevulinic acid (ALA)-photodynamic therapy (PDT) or secondary surgery after the primary excision. In total, 20 patients with preoperative clinical diagnoses of nevi underwent in situ resection. The postoperative pathological diagnoses confirmed all cases were BCC. Ten patients received PDT twice after the primary excision, and 10 cases received extended resection after the primary excision. Patients were followed up for 8 months at least, and the 2 groups did not show statistically significant differences in the recurrence rate, while the PDT group had better results in terms of economic burden, healing period, and cosmetic satisfaction than the group with secondary surgery. Our study demonstrates that ALA-PDT can sever as a considerable remedial treatment for the BCC patients who have not accepted radical resection due to primary clinical misdiagnosis.
