Nummular dermatitis

Nummular dermatitis, also referred to as discoid eczema, is a chronic, relapsing inflammatory skin disease characterized by discrete, coin-shaped (nummular) or oval eczematous plaques It predominantly affects the integumentary system of middle-aged and older adults, though it can occur at any age, most frequently involving the extensor surfaces of the lower and upper extremities and less commonly the trunk Pathophysiologically, it is driven by epidermal barrier dysfunction, xerosis, and immune-m...

Nummular dermatitis, also referred to as discoid eczema, is a chronic, relapsing inflammatory skin disease characterized by discrete, coin-shaped (nummular) or oval eczematous plaques Lesions classically manifest with intense pruritus and transition from clustered erythematous papules and oozing microvesicles into crusted, scaling, and lichenified plaques

It predominantly affects the integumentary system of middle-aged and older adults, though it can occur at any age, most frequently involving the extensor surfaces of the lower and upper extremities and less commonly the trunk Pathophysiologically, it is driven by epidermal barrier dysfunction, xerosis, and immune-mediated cutaneous inflammation, which may present as an idiopathic disorder or as a morphological variant of atopic dermatitis Lesions classically manifest with intense pruritus and tr...
