This case describes a 12-year-old girl with a lifelong, patterned cicatricial alopecia arising shortly after birth, ultimately diagnosed as halo scalp ring (HSR). The alopecia formed a large, semi-annular band extending from the temporal to occipital scalp, corresponding to areas affected by neonatal caput succedaneum complicated by residual necrosis and ulceration. HSR is a rare, likely underreported perinatal pressure-induced alopecia caused by ischemic injury from prolonged pressure of the cervix during delivery. While most cases are transient and non-scarring, severe ischemia can result in permanent cicatricial alopecia, as in this patient. Diagnosis is primarily clinical, supported by dermoscopy showing white scarred areas with erythema, and relies heavily on birth history. The condition is benign, requires no systemic workup, and management is typically reassurance, with surgical options considered for cosmetic concerns.
