Example of haemosiderin deposits taken into account when calculating the NEMO score. (A) Two micro-haemorrhages of relevant size are evident in the cuticle border, as a result of erythrocyte extravasation following the rupture of capillaries. The consequent haemosiderin deposits assume a round form; (B) numerous synchronous micro-haemorrhages are observed aligned in the distal row of the cuticle. Synchronicity of events is defined by the presence of haemosiderin deposits in the distal row of capillaries aligned at the same level [16]; (C) a haemosiderin deposit that mirrors the shape of a capillary loop is shown. This aspect is considered indicative of a micro-thrombosis [19]. NEMO, number of micro-haemorrhages.
