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.

Two giant-appearing capillaries on the right, one oval and one with a rounded enlarged apex, beside fine hairpin loops.
- Magnification:
- 250×
- Device:
- Smart G-Scope
No recorded physical calibration is available. Giant-capillary morphology is a visual assessment; the ≥50 µm diameter criterion is not confirmed.
An oval giant-appearing capillary right of center and another enlarged apex on the left, among finer hairpin loops.
- Magnification:
- 200×
- 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.
Several elongated giant-appearing capillaries on the right, with thick rounded apices and limbs. Finer and irregular loops lie to the left.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.40 × 1.35 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 14–109 µm. These are automated estimates, not manually validated measurements.
A giant-appearing capillary with a broad rounded apex on the left, beside smaller coiled and crossed loops.
- Magnification:
- 200×
- Device:
- Optilia Digital Capillaroscope
- 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.
Enlarged hairpin capillaries, some with tortuous limbs, especially on the left.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.27 × 1.28 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 23–42 µm. These are automated estimates, not manually validated measurements.
Two enlarged central apices, one rounded and one angular, surrounded by narrower capillaries.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.36 × 1.33 mm
For the subset of apices with stable automated measurements, estimated widths span approximately 13–51 µm. These are automated estimates, not manually validated measurements.
Several enlarged rounded capillary apices with relatively slender limbs, especially near the center-left and right edge.
