Professor of Medicine, University of Zaragoza
Dr. Borja del Carmelo Gracia Tello is an internist and academic director of the Unidad de Enfermedades Autoinmunes Sistémicas (Systemic Autoimmune Diseases Unit) at Hospital Clínico Universitario Lozano Blesa (Zaragoza), and Professor of Medicine at the University of Zaragoza. After completing his specialist training in Internal Medicine, he undertook a research fellowship with Prof. David Isenberg at University College London, where he gained advanced expertise in systemic autoimmune diseases and lupus. His clinical and research work focuses on microvascular involvement and connective tissue diseases, with a particular interest in systemic sclerosis, biomarkers of disease activity, and imaging-based tools to improve early diagnosis and risk stratification.
Dr. Gracia Tello has coordinated and participated in multiple national and international research projects, including studies on systemic sclerosis–associated pulmonary arterial hypertension, sarcoidosis, giant cell arteritis, and COVID-19. He is the lead inventor of a project on the digitalisation and automated analysis of nailfold capillaroscopy, developed through the GEAS (Grupo Español de Enfermedades Autoinmunes Sistémicas) of SEMI (Spanish Society of Internal Medicine), and co-author of the CAPI-Score and CAPI-Detect algorithms for quantitative videocapillaroscopy. As Chair of the Scientific Advisory Board, he provides strategic and scientific oversight for Capillaroscopy.com, ensuring that all educational content is rigorous, up-to-date, and aligned with international standards of care.

Coiled apices, simple hairpin loops and broad tortuous capillaries. An elongated brown hemorrhagic deposit lies above the center-right.
Recorded diagnosis: Buerger disease
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.34 × 1.32 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 11–38 µm. These are automated estimates, not manually validated measurements.
Enlarged capillaries with rounded apices and tortuous limbs. A faint brown mark lies above the center.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.33 × 1.31 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 20–48 µm. These are automated estimates, not manually validated measurements.
Capillaries with rounded apices, mild tortuosity and a folded central loop. A small brown-red microhemorrhage lies near the right edge.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.25 × 1.27 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 11–23 µm. These are automated estimates, not manually validated measurements.
Two giant-appearing capillaries with thick rounded apices, mixed with finer loops. Brown hemorrhagic deposits lie above the row.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.29 × 1.29 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 16–56 µm. These are automated estimates, not manually validated measurements.
Several giant-appearing capillaries with broad rounded or angular apices. Dense dark hemorrhagic deposits lie above them.
- Device:
- Optilia
- Field of view (W × H):
- ≈ 1.71 × 1.28 mm
The field of view uses the supplied Optilia calibration. Giant-capillary morphology is a visual assessment; the ≥50 µm diameter criterion has not been confirmed by individual measurement.
Capillaries with paired or accessory apices, especially near the center-right. Blue-black surface fragments lie above the row.

- ≈ 2.23 × 1.25 mm
For nonbranching apices with stable automated measurements, estimated widths span approximately 13–35 µm. These are automated estimates, not manually validated measurements.
A giant-appearing capillary near the center, surrounded by narrower hairpin loops. Dense hemorrhagic deposits lie above the left side.
- Magnification:
- 200×
- Device:
- Optilia Digital Capillaroscope
- Field of view (W × H):
