Dermoscopy of Pigmented Purpuric Dermatoses (Lichen Aureus): A Useful Tool for Clinical Diagnosis

Dermoscopy of Targetoid Hemosiderotic Hemangioma: A Morphological Study of 35 Cases

“…The second most common pattern was composed of a reddish-violaceous or reddish-brown homogeneous area that occupied the whole lesion, most often with vascular and white structures, found in 8 cases (22.8%). This pattern has also been described to be rarely associated with some vascular tumors (microvenular hemangioma [11] and retiform hemangioendothelioma [12], to name a few), aneurysmatic dermatofibromas [13], purpuric dermatosis [14], and some amelanotic melanomas [15,16]. Menzies et al [15] found that some of the most positive predictors of amelanotic or hypomelanotic melanomas were irregularly shaped depigmentation (white structures), the presence of more than one shade of pink (reddish homogeneous pigmentation), and peripheral light brown structureless areas (reddish-brown homogeneous areas), and therefore nontargetoid THH can be considered a mimic of melanoma [7,15].…”

Dermoscopy in General Dermatology

“…From 1955 to January 2005, we found 61 dermoscopy articles reporting a variety of different indications in the context of NPSD [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61]. Preferentially we did not include dermoscopy articles in which the differential diagnosis to pigmented skin tumors was discussed.…”

Blue-gray blotch: A helpful dermoscopic finding in optimal biopsy site selection for true vasculitis

“…However, dermoscopic findings of purpuric lesions have rarely been reported, and then only in studies of single or small numbers of cases. [2][3][4][5] The aim of the present study was to identify characteristic dermoscopic features that would help select the optimal biopsy site for diagnosis of true vasculitis.…”

“…Dermoscopic variables were adopted from previous literature describing the dermoscopic features of inflammatory purpuric lesions. [2][3][4][5] Fifteen cases of true vasculitis and 15 cases of vasculopathy were included in this study. Statistical analysis was performed using Fisher's exact test.…”
