title: CD4+ CD56+ hematodermic neoplasm.
abstract: We report a case of a 75-year-old man with a cutaneous CD4+CD56+ hematodermic neoplasm. CD4+CD56+ hematodermic neoplasms are rare and commonly present as cutaneous lesions. This is an important diagnosis in the differential diagnosis of cutaneous hematologic malignancies because of the extremely poor prognosis.
