Which breast development finding is typical of a preterm newborn?

• A. Flat Areolae Without Palpable Breast Buds
• B. Abundant Lanugo
• C. Smooth Pink Skin With Visible Veins
• D. Deep Creases On Soles

Answer: (A)

Understanding how gestational age affects newborn anatomy helps explain this finding. In preterm infants, breast tissue is immature, so the areola remains flat and there are no palpable breast buds. This lack of breast development is a normal sign of prematurity, reflecting overall underdeveloped glandular tissue at earlier gestational ages. Other features listed relate to maturity in other ways but aren’t about breast tissue. Abundant lanugo is a general prematurity clue, not a breast finding. Smooth pink skin with visible veins points to thin, low-fat skin often seen in preterm babies but again not a breast-specific sign. Deep creases on the soles increase with maturity and aren’t a breast indicator either. So the description that best fits a preterm newborn regarding breast development is flat areolae without palpable breast buds.
