Proximal nailfold microhemorrhage events are manifested as distal cuticular (eponychial) hemosiderin-containing deposits (CEHD) (syn. Maricq sign) and can aid in the diagnosis of dermatomyositis and systemic sclerosis.

CONCLUSIONS AND RELEVANCE: CEHD are in fact hemosiderin-containing deposits that can reflect the active inflammatory phase of microvascular injury occuring in autoimmune disorders such as DM and SSc. CEHD can be visualized and documented at the bedside with tools commonly available to any dermatologist (portable dermatoscope and compact digital camera). PMID: 27267184 [PubMed - in process]
