We report a case of a 55-year-old African American woman who developed intensely pruritic papules and plaques on bilateral hands. Histological examination demonstrated acute spongiotic dermatitis with lymphocyte exocytosis into the epidermis. Taken together, a diagnosis of lichen planus–like atopic dermatitis was made. This case serves to highlight that lichen planus–like atopic dermatitis can develop on hands and that it presents as spongiotic dermatitis with lymphocyte exocytosis into the epidermis. Correlating the clinical presentation with histopathological findings will assist in establishing the diagnosis and guiding appropriate management. Copyright © 2019 Wolters Kluwer Health, Inc.
