What is the recommended treatment for a low-risk basal cell carcinoma on the trunk or extremities?

• A. Mohs micrographic surgery
• B. Surgical excision
• C. Electrodesiccation and curettage
• D. Radiation therapy

Answer: (C)

In the context of treating low-risk basal cell carcinoma (BCC) on the trunk or extremities, electrodesiccation and curettage is recognized as a suitable treatment option. This technique involves scraping away the cancerous tissue with a curette after using an electrical current to desiccate the tumor. It is particularly effective for superficial BCCs and offers several advantages including minimal scarring and the potential for quick healing.

Electrodesiccation and curettage is often chosen for low-risk lesions because it is less invasive compared to more extensive surgical options, making it an appropriate alternative for patients who might prefer a less aggressive treatment approach. This option is especially advantageous when the tumor is small and well-defined, allowing for a high rate of local control while minimizing the risks associated with larger surgical procedures.

In treating BCCs, other methods such as Mohs micrographic surgery and surgical excision are indeed effective, but they are typically reserved for high-risk lesions or those located in cosmetically sensitive areas where precise margins are crucial. Radiation therapy may be utilized in specific contexts but is not considered a first-line treatment for low-risk BCC. Thus, the selection of electrodesiccation and curettage aligns with both the nature of the tumor and
