Glomerular VesselsThis glossary term has not yet been described.[1]

Glomerular vesselsThis glossary term has not yet been described. are the dermoscopic manifestations of tortuous, dilated capillaries. They are named as such because their morphologyThis glossary term has not yet been described. is reminiscent of the convoluted capillaries that comprise the glomerular apparatus of the kidney. Glomerular vessels are larger than dotted vesselstiny pinpoint vessels flat melanocytic lesions inflammatory diseases Bowen disease and can be positioned in clusters throughout the lesion. Histologically these vesselsThis glossary term has not yet been described. correlate to dilated capillaries in the dermal papillae and papillary dermis (Felder et al., 2006). Most commonly, glomerular vessels are associated with SCCs, in which the glomerular vessels are prin- cipally distributed focally in clusters and at the periphery of the lesion together with hyperkeratosis (i.e., scaly surface). In a study of BowenThis glossary term has not yet been described.’s disease (BD), 80% of pigmented BD and 100% of nonpigmented BD displayed glomerular vessels. In another study, glomerular vessels were seen in 81.2% of BD cases with a PPV of 61.9%. In contrast, glomerular vessels were seen in only 1.3% of melanomas, 12.2% of SKs, and 7.1% of invasive SCCs. Glomerular vessels can also be seen in CCA where the vessels will be arranged in a string of pearlsCoiled or dotted vessels arranged in lines clear cell acanthoma distribution, in psoriasisThis glossary term has not yet been described. where the vessels are distributed throughout the lesion in an organized pattern, and in stasis dermatitisThis glossary term has not yet been described. where these vessels will be visible in normal appearing skinThis glossary term has not yet been described.. Lastly, glomerular vessels can also be seen in melanomaThis glossary term has not yet been described., especially within metastatic foci.
