Teaching point
Subpapillary venous plexus: it may be seen in healthy individuals, so it does not define pathology by itself.
Measurements and calibration
For the subset of apices with stable automated measurements, estimated widths span approximately 9–27 µm. These are automated estimates, not manually validated measurements.
Clinical caveat
This image illustrates a visual finding and should be interpreted with acquisition quality, distribution across fingers, clinical context, and serology when relevant.
