The main macroscopic features of 4 cases presented here are erythroderma-like lesions and solid papules. The former covers extensive areas over entire trunk and extremities, especially extensor surfaces. The latter is observed mainly on flexor surfaces of extremities and around the former. The axillae, inguinal regions, cubital and popliteal fossae, and big furrows on abdomen are spared from these lesions. Rashes appear first as papules and form erythroderma-like lesions through their assembly and confluence. Histologically, both show almost the same findings. Patients are older males with no general symptoms except itching. Although the course is chronic, lesions improve slowly and heal only after years.
