Spectrum of Lung and Cardiovascular Diseases in Association with Pulmonary Interstitial Glycogenosis

“Pulmonary Interstitial Glycogenosis (PIG) associated with a spectrum of neonatal pulmonary disorders”, reported by Cutz et al represents one of the largest series published to date. The report included twenty-eight cases of lung or cardiac disorders with coincident diffuse, patchy, or focal PIG reviewed in Division of Pathology, The Hospital for Sick Children. The authors focused on reporting a spectrum of disorders associated with PIG and described four clinicopathological subgroups including imaging, ultrastructural findings, and clinical outcome. The present paper highlights the main findings reported by Cutz et al, and a review of literature is also presented.
