Sucking pads in infancy: A physiologic finding – A case report

Sucking pads are benign, self-limiting skin findings that develop on the red lip in infants as a result of repetitive suction and pressure during feeding. Although well described in pediatric dermatology, documentation of these lesions in infants with skin of color is limited, which may cause diagnostic uncertainty. We present a case of a 41-day-old infant with skin phototype V and a 2-week history of progressive fixed darkening and mild scaling of the lips. The mucosal areas were spared and there was no evidence of central cyanosis, clinically consistent with sucking pads. This case highlights the importance of recognizing sucking pads as a cause of lip dyspigmentation in infants across all skin phototypes and understanding normal physiologic variations among diverse populations. Increased representation of pediatric skin of color in educational resources is critical to ensure equitable and accurate clinical assessment.
