Pathology · single question

All of the following are features/complications of herpes zoster (shingles) EXCEPT:

  1. Bilateral lesions crossing the midline
  2. Unilateral dermatomal distribution
  3. Postherpetic neuralgia
  4. Painful vesicular eruption
Show answer and explanation

Correct answer: A. Bilateral lesions crossing the midline

  • A. Correct (the exception). Zoster characteristically follows a single dermatome and STOPS AT THE MIDLINE — bilateral lesions crossing the midline are NOT typical (and would suggest immunocompromise/disseminated disease).
  • B. Unilateral dermatomal distribution is the hallmark of shingles.
  • C. Postherpetic neuralgia is a well-known complication.
  • D. Painful grouped vesicles are typical of the acute eruption.
