Lichen planus pemphigoides (LPP) is a very rare autoimmune blistering disease associated with lichenoid skin changes. Unna-Thost palmoplantar keratoderma (PKK) is a type of diffuse palmoplantar keratoderma that mostly affects the palms of the hands and soles of the feet. It usually begins in early childhood. We present a unique case of coexistence of LPP, Unna-Thost PPK, and atopic dermatitis (AD). To our knowledge, there are three reported cases of both LPP and Unna-Thost PPK and a few reports of coexistence of Unna-Thost PKK and AD.
