A capilarite resulta do extravasamento de glóbulos vermelhos de capilares com vazamento para a derme e se manifesta inicialmente como máculas finamente pontilhadas róseas à púrpura, afetando mais comumente os membros inferiores. À medida que o ferro é liberado e convertido em hemossiderina, a pele fica dourada ou marrom. Vários padrões de capilarite foram descritos e receberam nomes separados, dependendo da distribuição, curso de tempo, extensão e grau de pigmentação, e presença ou não de espessamento epidérmico. Os processos subjacentes envolvidos em todas essas variantes são muito semelhantes e de causa desconhecida. A histologia pode mostrar inflamação leve ao redor dos capilares, mas sem vasculite. | |||
