What type of lesion on the face should be treated with Mohs micro surgery?

• A. Low-risk lesions
• B. Large face lesions
• C. Trunk lesions
• D. Extremity lesions

Answer: (B)

Mohs micrographic surgery is particularly indicated for certain types of lesions due to its precision in excising cancerous skin while preserving as much healthy tissue as possible. The technique is especially beneficial for lesions on the face because of the complex anatomy and vital structures present in this area.

Large lesions on the face pose a significant challenge, as they are more likely to invade deeper layers of skin and surrounding tissues. Mohs surgery allows for the immediate and thorough examination of the excised tissue to ensure clear margins, reducing the chance of recurrence. This is crucial for larger facial lesions, where traditional excision methods could increase the risk of incomplete removal and potential cosmetic complications.

In comparison, low-risk lesions, trunk lesions, and extremity lesions might not require the same level of meticulous tissue preservation and margin control because they either have a lower likelihood of aggressive behavior or are located on areas where the anatomical structures are not as intricate as on the face. Therefore, for larger lesions specifically located on the face, Mohs micrographic surgery is the preferred treatment choice, ensuring both oncologic control and optimal cosmetic outcomes.
