An infant presents with a mucous-like patch on the palate. No image is provided. What is the most likely diagnosis?

  1. Natal teeth
  2. Epstein pearls
  3. Congenital syphilis (mucous patch)
  4. Bohn's nodules
Show answer and explanation

Correct answer: D. Bohn's nodules

  • A. INCORRECT — Natal teeth are teeth present at birth, not mucous patches.
  • B. INCORRECT — Epstein pearls are epithelial inclusion cysts found at the midpalatal raphe in newborns. They appear as white/yellow midline papules. Although the distinction is subtle, Bohn's nodules appear on the alveolar ridges/lateral palate while Epstein pearls are midline. Source notes Epstein pearls was not offered as an option.
  • C. INCORRECT — Congenital syphilis mucous patches are greyish, slightly elevated lesions containing treponemes; they occur in older infants/children with syphilitic infection.
  • D. CORRECT — Bohn's nodules are mucous gland remnants (keratin-filled cysts from minor salivary glands) found on the alveolar ridges and palate of newborns. They appear as small white/yellowish mucous-like lesions on the palate. Per the source, Epstein pearls was not an answer choice in the original question.
