[Microangiopathic changes and functional disorders of nail fold capillaries in dermatomyositis].
We report on a 70-year-old female patient with dermatomyositis. The connective tissue vascular bed was studied with capillaroscopy to evaluate morphological and functional changes of skin capillaries. Capillaroscopic findings showed morphological alterations such as rarefication of capillaries, avascular fields and tortuosity of nailfold capillaries. In addition, fluorescence-videomicroscopy showed pathologically increased transcapillary diffusion of dye in the apex region of nutritive skin capillaries. Increased capillary leakage probably contributed to the development of oedema in our patient. Immunosuppressive therapy combined with intensified manual lymphatic drainage was successful.
