[READINESS SEED] Which eyelid malignancy is correctly matched to its recommended clinical excision margin?
Show the answer and explanationAnswer and explanation
Answer: A. Eyelid melanoma — up to 10 mm
Clinical margins scale with invasiveness — nodular BCC ≥2 mm, infiltrative BCC 3 mm, SCC 5 mm, eyelid melanoma up to 10 mm — so only the melanoma–10 mm pairing is correct. The tempting near-miss is nodular BCC–5 mm, which borrows the SCC figure.
Clinical pearl: Compound tumor-plus-margin options force you to hold the whole ladder in mind, not just one number.
