Anti-U3 RNP systemic sclerosis: irregular loops
Irregular enlarged loops in the anti-U3 RNP case. Although giants remain present, the final report classifies the overall microangiopathy as late.
Source study context
There is marked capillary loss (4.9/mm), architectural disorganization, frequent dilations, giant capillaries in 14.9% of capillaries, and abnormal or ramified forms. This pattern was classified by the CAPI-Detect algorithm as active; however, due to the frequent features characteristic of late-stage involvement, it was ultimately classified as such in the final report.
Measurements and classification refer to the described study or visit; they are not new measurements of this image.

Teaching point
Review several fingers before concluding that density is low or the pattern is abnormal.
Clinical caveat
