Abstract
Mutations in the surfactant protein C gene (SFTPC) are responsible for hereditary interstitial lung disease (ILD), which is a rare disease. We herein report a patient with a clinical history of endogenous lipoid pneumonia in infancy who developed diffuse progressive pulmonary fibrosis in adulthood associated with SFTPC mutations. A surgical lung biopsy and genetic sequencing revealed fibrotic interstitial pneumonia and two SFTPC mutations (c.215G>A and c.578C>A). Based on these findings, we diagnosed the series of lung diseases as sporadic ILD caused by SFTPC mutations. Physicians should suggest genetic sequencing in patients with early-onset ILD.
