Chronic relapsing vesiculosquamous dermatitisĬhronic relapsing vesiculosquamous dermatitis is a common pattern of palmar and finger dermatitis, in which episodes of acute vesicular dermatitis are followed by chronic scaling and fissuring. It is likely this form of dermatitis is triggered by sweating ( hyperhidrosis) such as in hot and/or humid weather and with emotional stress. Vesicular hand dermatitis is also known as pompholyx. Intensely itchy crops of skin-coloured blisters arise on the palms and the sides of the hands and fingers. Other sites of the body may or may not be affected. Discoid eczemaĭiscoid eczema ( nummular dermatitis) tends to affect the dorsal surfaces of the hands and fingers as circumscribed plaques.
Patients will typically have signs of atopic dermatitis elsewhere such as in the flexures. It may manifest as a discoid or vesicular pattern of eczema. It usually involves the backs of the hands and around the wrists.
Skin pronlems with blisters that weep skin#
Ītopic hand dermatitis is due to impaired skin barrier function and is triggered by contact with irritants. Ĭontact allergy is a delayed hypersensitivity reaction with elicitation and memory phases involving T lymphocytes and release of cytokines. In atopic dermatitis, a deficiency in or defective function of the filaggrin protein in the stratum corneum leads to barrier dysfunction resulting in water loss and easy penetration by irritants and allergens. Water loss and inflammation lead to further impairment of barrier function. These can damage the outer stratum corneum, removing lipids and disturbing the skin’s barrier function. Irritants include water, detergents, solvents, acids, alkalis, cold, heat and friction. Hand dermatitis is frequently caused or aggravated by work when it is known as occupational dermatitis.
