In patients with thickened ASM mass only in the central bronchi, they observed ASM hyperplasia without hypertrophy, whereas in patients with thickened ASM in the entire airway tree, they observed the predominance of ASM hypertrophy, with mild hyperplasia localized only to the bronchi, the airways available to us for endobronchial biopsy in the children in our report (5).
