Efficacy of narrow-margin excision of well-demarcated primary facial basal cell carcinomas

Narrow margins (1-3 mm) are inadequate for the excision of small, well-demarcated, primary nodular BCCs of the face. To avoid repetitive operations and the risk of recurrence in anatomically sensitive areas, these tumors should be treated with standard wide margins (eg, 4 mm), or have Mohs micrographic surgery for histologic margin control.
