A 30-year-old non-smoking man was referred to our hospital for the further examination of abnormal shadows revealed by chest X-ray. He had mild shortness of breath. Chest computed tomography revealed a fine-grained dendritic shadow with diffuse calcification in both lungs and as well as emphysematous changes in the upper lung lobes. A surgical lung biopsy histology revealed diffuse pulmonary ossification complicated with lung laceration, vascular disruption, hemosiderosis, and emphysema, suggesting vascular Ehlers-Danlos syndrome (vEDS). However, the patient had no external physical signs or family history of vEDS and no COL3A1 gene mutations. We are closely monitoring this patient in the clinic.
