Preserved capillary density with anticoagulation-related hemorrhagesA 74-year-old male with no rheumatologic history, on apixaban for permanent atrial fibrillation. Nailfold video capillaroscopy of the right fourth finger demonstrates preserved capillary density without capillary dropout. There are no giants or enlarged capillaries. Hemorrhages are present, related to chronic anticoagulation.
Dermatomyositis with giant and ramified capillaries25-year-old male with anti-TIF-1γ antibody-positive dermatomyositis. Nailfold video capillaroscopy demonstrates significant microvascular architectural abnormalities characterized by enlarged and giant capillaries and multiple ramified (bushy) capillaries consistent with neoangiogenesis. No microhemorrhages are identified.
