Deposição dérmica de hemossiderina causa uma descoloração marrom-amarelada ou bronzeada da pele. A deposição pode ser focal, como observado subsequente a extravasamento repetido de glóbulos vermelhos (p.ex., em associação com hipertensão venosa ou vasculite crônica) ou por sobrecarga generalizada de ferro (p.ex., hemocromatose). A hemossiderina pode estimular a melanogênese e, portanto, a cor se deve a proporções variáveis de hemossiderina e melanina. | |||

Dermal haemosiderin deposition causes a yellowish-brown or bronze discolouration of the skin. The deposition may be focal as seen following repeated extravasation of red blood cells (e.g. in association with venous hypertension or chronic vasculitis) or from generalised iron overload (e.g. haemochromatosis). Haemosiderin may stimulate melanogenesis and thus the colour is due to variable proportions of haemosiderin and melanin. | |||
