Cutaneous Manifestation	Subtype, if Applicable	Morphology	Additional Clinical Findings
Alopecia	Androgenetic alopecia	Hair loss from the anterior hairline moving posteriorly or thinning at the vertex scalp	Associated with worse clinical outcomes in some studies148,149
	Telogen effluvium	Diffuse hair shedding 2–3 mo after a stressor150,151
Gianotti-Crosti-like rash		Pruritic erythematous papules and vesicles on elbows, anterior thighs, and bilateral popliteal fossa coalescing into plaques.152	Rash started 18 d after onset of symptoms, 13 d after +COVID test, and 3 d after resolution of all respiratory and systemic symptoms.
SDRIFE-like		Erythematous rash on bilateral axillae and antecubital fossae, which subsequently extended to trunk and inner thighs153,154
Grover-disease-like		Red papules and papulovesicles distributed on the trunk155 Note: some evidence suggests clinical overlap with vesicular, or “varicella-like” eruptions
Erythema elevatum diutinum-like		Firm symmetric smooth nodules on extensor surfaces, particularly joints156
Reactive infectious mucocutaneous eruption (formerly known as Mycoplasma-induced rash and mucositis)		Shallow erosions of the vermilion lips, hard palate, periurethral glans penis.157	Reported patient with +COVID PCR 1 wk before rash onset, and again positive at rash onset. Mycoplasma PCR negative, IgM negative, IgG positive (consistent with past exposure).
Enanthems (eruptions of the mucous membranes)		83% (5 patients) with petechial enanthem ± macular enanthem158	Recorded from a group of 21 patients with COVID-19 and skin rash ranging from papulovesicular, purpuric periflexural, and erythema multiforme-like.
Oral lesions		Aphthous-like, ulcerations, and macules, tongue depapillation, angular cheilitis, ulcers, blisters, white plaques, dark pigmentations.159	Etiology postulated to be multifactorial. Hypotheses include direct action of SARS-CoV-2 on oral mucosal cells, coinfection, immunity impairment, or adverse drug reactions160
Acute genital ulcers (Lipschütz ulcers)		Necrotic ulcers with raised, sharply demarcated borders of the labia minora with no evidence of “kissing lesions.”161	Single oral aphtha was also observed, with no cutaneous involvement
Transient rash in newborns		Transient “rash” (morphology not described) in babies born to mothers with COVID-19.162 Mottling noted in a neonate with sepsis and +COVID-19.163
