Successful treatment of a giant keratoacanthoma-like squamous cell carcinoma in the eyebrow using surgery combined with photodynamic therapy: A case report.

Abstract Keratoacanthoma (KA)-like squamous cell carcinoma (SCC) is inclined to be diagnosed as KA due to its resemblance to KA in appearance. A giant facial KA-like SCC has aggressive growth and malignant metastasis, and seriously affects health and aesthetics. Prompt and appropriate treatment is extremely crucial and is a great challenge. Herein, we report a case of surgery combined with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in the successful management of a giant KA-like SCC in the left eyebrow of an elderly woman, providing reference for more efficient disposal of such cases in clinic.
