Dermatomyositis with giant and ramified capillaries
25-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.
