Nail dermatoscopic (onychoscopic) features of nail lichen planus: A cross‐sectional study

Description of the most severe signs in nail lichen planus: a strategy to contribute to the diagnosis of the severe stage

“…and Grover et al. such as nail bed dyschromia and lunula changes, including stippled erythema, homogeneous erythema, flame‐shaped lunula, or yellow lunula, exist 3 . Onychomadesis can also occur.…”

“…Gavilanes-Coloma et al 10 Evidence on features and classification of NLP remains scarce but has helped identify involvement in a significantly larger number of nails as compared to clinical examination alone. 3 In this study, we sought to provide data for an updated classification for the severe stage of NLP, based on the characteristics of patients with NLP and its relation to anonychia and dorsal pterygium.…”

“…2 NLP diagnosis is mainly clinical, but diagnostic confirmation with histopathological analysis is recommended, especially in early-stage patients, being mandatory for monodactylous NLP. [3][4][5] In recent years, dermoscopy has emerged as a useful noninvasive imaging tool used at the time of physical examination of the nails, allowing a more careful assessment of NLP signs. 6 The manifestations of NLP are typical and suggestive of the disease in most patients and depend on the time of diagnosis and the affected anatomical site, including the matrix (proximal and distal), nail bed, and in some cases, the periungual tissues.…”

“…2,5,8,9 Other findings described by Kharghoria et al and Grover et al such as nail bed dyschromia and lunula changes, including stippled erythema, homogeneous erythema, flame-shaped lunula, or yellow lunula, exist. 3 Onychomadesis can also occur. Nail bed involvement can be associated with onycholysis, splinter hemorrhages, and mild subungual hyperkeratosis.…”
