Journal of Dermatology 2017; 44: e336-e337 type DM and either malignancy or interstitial lung disease remains unclear. Some studies reported that more than half of Wong-type patients develop malignancy, 1 while other studies suggest a risk for interstitial lung disease. 4 Serum anti-MDA5 antibody was detected in a previous case but without malignancy. 5 In another case, malignancy was detected 5 years after the diagnosis. 3 It has yet to be elucidated whether Wongtype DM is significantly associated with malignancy; therefore, thorough examinations and careful follow up are necessary in cases of this type DM.
