Psoriatic erythroderma
Published in Biju Vasudevan, Rajesh Verma, Dermatological Emergencies, 2019
Dull nails, ridging, thickening, and distal onycholysis are seen. Sometimes shedding of the nails in the form of onychomadesis is also present. Nail pitting commonly seen in psoriasis can also be seen in reactive arthritis and other eczematous disorders like atopic dermatitis. Salmon patch or oil drop sign is fairly specific for psoriasis. In the acute type of erythroderma typical nail changes might not be present, and the nails might just show Beau lines (Figure 14.4) or onychomadesis [3].

Onychomadesis is an acute non-inflammatory condition affecting the nail matrix that results in spontaneous separation of the nail plate from the matrix starting at the proximal end. A severe systemic illness or trauma may cause spontaneous separation of the nail plate from its matrix, which may be due to decrease in the blood supply.
Peeling, and hand, foot, and mouth disease
Published in Alisa McQueen, S. Margaret Paik, Pediatric Emergency Medicine: Illustrated Clinical Cases, 2018
Hand, foot, and mouth disease is a common viral illness caused by coxsackie A16 and enterovirus D71, as well as other species in the Enterovirus genus. The typical disease presentation includes fever, painful oral ulcers, and a rash that frequently involves the palms and soles. Onychomadesis, or shedding of the nails, has been reported as a complication of the illness, typically presenting about 4 weeks after initial symptoms resolve (Bracho et al., 2011; Wei et al., 2010). Subsequent nail growth is normal.

Although onychomadesis has been previously reported following KD,10 this is the first time onychomadesis has been reported in association with coronavirus-associated KD. Onychomadesis results from complete toxicity of the nail matrix and presents with shedding of the nail or a proximal sulcus that splits the nail plate into two parts.11 Onychomadesis has been associated with hand, foot, and mouth disease and typically occurs within 2 months of the infection.11 A recent report of a child who presented with onychomadesis was found to have a previously missed KD diagnosis upon further investigation.12 Our report suggests that physicians should be suspicious of undiagnosed KD and potentially coronavirus in a patient presenting with onychomadesis of unknown cause.
Optimal diagnosis and management of common nail disorders
Published in Annals of Medicine, 2022
Onychomadesis is defined as a complete separation and eventual shedding of the nail plate (Figure 10(B)). It is a more extreme presentation of Beau’s lines and develops about four to eight weeks after the initial insult [132]. Complete loss of continuity with the matrix can occur when the inciting event is severe enough to cease nail production. If the subsequent depression that develops reaches a maximum depth, the nail plate will separate from the matrix [125,133]. As the proximal nail plate grows out, it undermines the distal plate, wedging it upward. Over time, the distal nail plate will shed [115]. In severe cases, inflammation and granulation tissue can be noted in the lateral nail folds [132].
