Two cases of halo scalp ring

Area of Science:

• Dermatology
• Neonatology
• Pediatrics

Background:

• Halo scalp ring (HSR) is a rare, non-scarring form of alopecia affecting newborns.
• This condition is characterized by annular hair loss on the scalp.
• HSR is understood to be a consequence of caput succedaneum, often caused by prolonged fetal head compression against the cervix during delivery.

Observation:

• This report details two new cases of halo scalp ring observed in full-term newborns.
• The infants presented with the characteristic annular alopecia shortly after birth.

Findings:

• The two cases presented align with the established pathophysiology of halo scalp ring.
• These findings reinforce the association between perinatal pressure and the development of HSR.

Implications:

• Understanding the etiology of HSR is crucial for accurate diagnosis and parental reassurance.
• This report contributes to the limited case literature on halo scalp ring, aiding clinicians in recognizing this benign neonatal condition.
