Following publication of the original article [1], it was reported that there was an error in the caption for Fig. 1A.
The caption previously read: “Fig. 1A US image showing patchy mild changes in echogenicity with hypoechoic areas and corresponding subcutaneous echogenicity in the vastus lateralis (cross-section) in a 26-year-old with Anti-NXP2.”
The correct caption is: “Fig. 1A Mild increased echogenicity in the vastus lateralis (cross section) and subcutaneous tissue with patches of hypoechogenicity in a 26-year-old with Anti-NXP2 DM.”
The article also contained several typographical errors, which have been corrected.
The original article [1] has been updated.
