The details of the 11 DC cases (plus this case report) who had both pulmonary disease and HSCT are listed in Table 3. All ages are reported in years. Triad denotes the classic triad of DC and consists of nail dystrophy, oral leukoplakia, and lacy reticular pigmentation.
Abbreviations: HSCT, hematopoietic stem cell transplant; CT, computerized tomography; DC, dyskeratosis congenita; DLCO, diffusion capacity for carbon monoxide; F, female; M, male; UIP, usual interstitial pneumonitis.
