Correct answer: D — Basal cell carcinoma – Mohs micrographic surgery

A pearly, telangiectatic, slowly-growing nodule on the nose is classic for nodular basal cell carcinoma. For facial BCCs (especially nose, periorbital, periauricular), Mohs micrographic surgery provides the highest cure rate with maximum tissue conservation. Standard excision with 3–4 mm margins is acceptable for low-risk BCCs in other locations.
