Large facial basal cell carcinoma treated with multimodal combination therapy.

Large basal cell carcinomas (BCCs) with mixed intratumoral histology can present treatment challenges. Although a single treatment modality may be appropriate for some portions of the tumor, it may prove to be inadequate or overly aggressive for others. We describe a patient with a large facial BCC who was referred to our clinic for Mohs micrographic surgery. Biopsies revealed both noduloinfiltrative and superficial patterns. To excise the tumor completely would have been disfiguring, and topical therapy alone would have been inadequate. A multimodal approach using Mohs micrographic surgery to excise the central nodular portion and topical imiquimod to treat the surrounding superficial portion resulted in an excellent clinical outcome. This approach, which minimizes morbidity by capitalizing on the benefits of various techniques, can be applied to any BCC demonstrating distinct nodular and superficial portions.
