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