Abstract and Remark
That is attention-grabbing and positively extra examine is required. My concern right here is that dilated blood vessels will be non particular and infrequently discovered when analyzing the scalp. However, there might be one thing necessary right here to review.
It might be that the dilated vessels are intently linked to the trichodynia that sufferers really feel. Many sufferers with COVID associated hair loss have uncommon signs like burning, tingling, buzzing.
A examine by Willimann and Trueb (in 2002) confirmed that dilated blood vessels seen within the scalp have been strongly related to trichodynia. One wonders whether or not the hyperlink between COVID and capillarectasia is the dilated blood vessels.
