Systemic Sclerosis with anti-U3 RNP: Late Microangiopathy
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.
Recorded measurements
- Capillary density
- 4.87capillaries/mm
- Enlarged capillaries
- 66.55%
- Giant capillaries
- 14.91%
- Hemorrhages
- 0.55/mm
Values from the saved analysis: density and hemorrhages per total analyzed length; percentages of the total capillary count. These are not measurements of an individual image and may differ from averages across fields.

Irregular enlarged loops in the anti-U3 RNP case. Although giants remain present, the final report classifies the overall microangiopathy as late.
