Teaching point

Is the image affected by pressure, reflections, cuticular trauma, or poor focus?

Measurements and calibration

For the subset of apices with stable automated measurements, estimated widths span approximately 20–33 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.
