“…In the main group ‘primary skin disorders linked with mental health’, the pathophysiological link with psychological stress was documented in the following disorders: some autoimmune bullous dermatoses (pemphigus vulgaris), 46 acne, 47 alopecia areata, 48 atopic dermatitis, 49 chronic spontaneous urticaria, 50 dermatomyositis, 51 hyperhidrosis, 52 infectious diseases (herpesviruses and warts), 53,54 lichen planus, 55 lupus erythematosus, 56 psoriasis, 57 rosacea, 58 systemic sclerosis, 59 seborrheic dermatitis, 60 telogen effluvium 61 and vitiligo 62 . These primary dermatoses are also associated with secondary psychiatric comorbidities which is a relevant aspect in other primary dermatoses that do not seem to present a pathophysiological link with stress, such as some examples of autoimmune bullous dermatoses (dermatitis herpetiformis, IgA bullous dermatosis), androgenetic alopecia, hidradenitis suppurativa, lichen sclerosus, toxic epidermal necrolysis, Stevens–Johnson syndrome, genodermatoses and cicatricial alopecias, particularly, primary neutrophilic cicatricial alopecias, such as folliculitis decalvans and dissecting cellulitis of the scalp 63–66 .…”
