Clinical-pathological correlates of congenital subglottic hemangiomas.

One hundred thirty-six cases of subglottic hemangioma in infants have been reported in the English -language literature; four additional cases are reported here. The clinical presentations, diagnostic work-ups, treatments, and outcomes are analyzed. Twenty-one patients died, 17 of whom underwent autopsy. The histology of the laryngeal pathology from seven of these patients was reviewed by the authors. Possible correlation between the pathological findings and the clinical presentation is made. Approaches to diagnosis and treatment are suggested based on these findings.
