A man with a vesicular rash in the distribution of the ophthalmic division of the trigeminal nerve has a lesion at the tip of the nose. What is the significance of this finding and the management?
Answer and explanation
Correct answer: D. It suggests nasociliary involvement
- Step 1: Shingles of the ophthalmic division can involve the eye. Step 2. A lesion on the tip of the nose, Hutchinson's sign, indicates involvement of the nasociliary nerve, which also supplies the cornea, so keratitis and uveitis are at risk. Answer: It suggests nasociliary involvement. Why not the others: It is not benign because eye complications may threaten vision. The rash is a viral dermatomal eruption, not impetigo. Steroid cream would not treat the infection.
