Which pairing correctly matches the behaviors?
[READINESS SEED] Two eyelid tumors are compared: one is locally invasive but almost never metastasizes, the other is less common but more prone to nodal and perineural spread. Which pairing correctly matches the behaviors?
Show the answer and explanationAnswer and explanation
Answer: A. The first is basal cell and the second squamous
Basal cell carcinoma is common and locally invasive but rarely metastasizes, whereas squamous cell carcinoma is less common but more likely to spread to nodes and along nerves. Matching behavior to tumor type guides how aggressively each is staged and followed.
Clinical pearl: This behavioral contrast is why node palpation and perineural assessment matter for squamous (and sebaceous) carcinoma but seldom change basal-cell management.
