Rheumatology Research Lead, Sura Biosciences Division
Dr. Miguel Antonio Mesa is a rheumatologist and internist, currently working as the rheumatology research line lead at Sura Biosciences Division. He also leads the microcirculation study group at the Colombian Association of Rheumatology. His academic interests focus on capillaroscopy and the use of advanced therapies in autoimmune diseases.
Contributed cases and studies (4)
Normal Pattern: Representative Case
Complete capillaroscopy study with preserved density, regular morphology, and no scleroderma-pattern features.
Systemic Sclerosis with anti-U3 RNP: Late Microangiopathy
Patient with systemic sclerosis, anti-U3 RNP antibodies, and severe microvascular disease with features of the late Cutolo pattern.
Anticentromere-Positive Systemic Sclerosis with Inter-Digit Pattern Heterogeneity
A 61-year-old Latin American woman with long-standing Raynaud phenomenon and recently diagnosed anticentromere-positive systemic sclerosis, showing markedly different capillaroscopic patterns across digits.
Mixed Connective Tissue Disease with an Unclassifiable Scleroderma-Like Pattern
A patient with mixed connective tissue disease, strongly positive anti-RNP antibodies, and a scleroderma-like capillaroscopic pattern featuring megacapillaries and arborizing forms.

- Field of view (W × H):
- ≈ 1.68 × 1.26 mm
200x capillaroscopy image showing a giant capillary with a coiled or ball-of-yarn appearance.
- Magnification:
- 200×
- Device:
- Inspectis Digital Capillaroscope
- Field of view (W × H):
- ≈ 1.68 × 1.26 mm
Unusual capillaroscopy image contributed as a personal reference case, showing widespread capillary thrombosis in a critically ischemic digit. The contributor highlighted the rarity of this finding and recommended clinicopathologic correlation.
- Magnification:
- 200×
- Device:
- Inspectis Digital Capillaroscope
- Field of view (W × H):
- ≈ 1.68 × 1.26 mm
A field from the normal reference study, showing the distal row of narrow loops. Use the full study to compare density and shape across fingers.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.35 × 1.32 mm
Irregular enlarged loops in the anti-U3 RNP case. Although giants remain present, the final report classifies the overall microangiopathy as late.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.39 × 1.34 mm
A disorganized field with enlarged loops and surface reflections from the inter-digit heterogeneity case. Other fields differ markedly; inspect the full study and its image-quality caveats.
- Magnification:
- 250×
- Device:
- Smart G-Scope
- Field of view (W × H):
- ≈ 2.32 × 1.31 mm
Irregular and branching forms in the anti-RNP-positive mixed connective tissue disease case. The source report describes a scleroderma-like pattern without an assignable Cutolo subtype.
