A 57-year-old woman with a diagnosis of antisynthetase syndrome (ASSD) underwent a nailfold videocapillaroscopy (NVC) showing a scleroderma pattern. Alterations in capillary morphology have been reported in adults with inflammatory myositis (IM) but only recently have the differences in NVC findings between these two diseases been established. ASSD is currently classified as a subset of IM, for which reason only a few studies in literature evaluate its specific hallmarks, showing nonspecific features of NVC in patients with polymyositis and dermatomyositis (DM) and antisynthetase antibodies. To our knowledge, this is the first description of ASSD capillaroscopy features, and the first report of NVC in ASSD with evidence of scleroderma pattern. Further studies are needed to define clearly frequency, typical features, and possible correlation with clinical and serological data of NVC changes in ASSD, differences between microangiopathy in ASSD and systemic sclerosis or DM.
